NOTHING WRONG WITH SU-57 VIDEOS! 4 videos are not too much! we like it. give us content. we see it. we love it. you win views. thanks for your videos and merry xmas!
It's completely unusual and not real, that static pictures show no movable control surfaces on the nozzles to execute the supposed 3D TVC compared to the animation.
@@kermittoad even if the roots are static, the fact that the nozzles are placed on an angle and not completely horizontal makes them 3D capable. simple maths summing 2 vectors that aren't parallel will result in a vector in another direction. obviously, this way will result in a less efficient thrust in the resulting direction, but when needed even 50% is still better than 0.
People don't realize Russia were the first nation to implement flat nozzles on there 1970's vtol yak-38/41 program, only for testing purposes of thrust vectoring are they mentioned, Quote from yakovlev: "a flat two-axis nozzle was designed in the second half of the 1970s for the Yak-41 vertical take-off and landing (VTOL) deck fighter. An original solution was used for its rotation - the nozzle was divided into three segments, which, rotating in opposite directions relative to each other, provided a deflection of the thrust vector in the vertical plane to an angle of 95° (at VTOL mode). For short takeoffs, the nozzle was set to 62°. This solution made it possible to use afterburner both in horizontal flight and in vertical mode"
@@paulroberts7429 yes but because of the geopolitical rivalry that persists to this day, technological innovation spearheaded by Russians (or the USSR of old) is evidently not allowed to be celebrated or even acknowledged 😂 Outsiders that just love aviation and aviation tech find this kinda weird. Jerry: "The Chinese copied our homework with the F-35!" Timmy: "Well, didnt Lockheed Martin get some F-35 homework from the Soviet Yak-41 program? They got all the blueprints when the USSR collapsed." Jerry: "Wait.. what?"
@@scroopynooperz9051 A couple of problems with the suggestion that the F-35 copied anything from the Yak-41. First, like its predecessor, the 41 had two small vertically mounted jet engines behind the cockpit to provide vertical lift. The idea of sticking vertical engines in the airframe to provide takeoff and landing lift was well known by everybody - it just wasn't used much because the problems it introduced nullified the benefits. The F-35's lift fan brings fewer problems with it and even solves a big problem that previous VTOL fighters - including the Yaks - had. Second, work on what would eventually be called the JSF program actually started way back in 1983 when the USMC approached DARPA for a supersonic, stealthy replacement for the Harrier. Lockheed's Skunk Works were already developing the required technologies when DARPA awarded them a classified contract in 1987, four years before Lockheed started cooperating with Yakovlev.
@@scroopynooperz9051man I thought the name Jerry was reserved for the Germans. Also Yak 41 might have been inspiration for the F-35 but that’s it, Yak 41 has a completely different system to vtol, and no stealth implementation, or the kind of tech that the F35 has. So when you say the Americans copied it you are literally just saying that because that’s what you want to believe.
Then purchased by Lockheed Martin for use in the F-35 program, no this is not an internet conspiracy. All data and some production pieces all exported legally years before the deep state made Russia the Pariah the complex needs to get it's funding. The JSF may have started work in the 80's but you do NOT pass up the opportunity to get your hands on all that research data, production pieces and potentially a couple of prototype examples of the Yak-41. LM won the competition with an outstanding design that Boeing couldn't match doing altitude VTOL tests while Boeing struggling at sea-level equivalent, even the program engineers knew they were in trouble. You can watch all about it on this platform, including why LM didn't just copy the Russians and all the relevant documentation. Hat's off to the Russian engineers who got this working with paper and pencil.
@@scroopynooperz9051 Yakovlev helped Lockheed with x35 vs x32 Boeing and harrier, I have Lockheed internal memorandums, Yakovlev built titanium fusalage and vtol mode flight suite, Soyuz built the 2 Rybinsk (RKBM), 1 Tumansky R-79V-300 afterburning vectoring-nozzle turbofan, with afterburner they helped Pratt and Whitney, and Zvezda built ejection seat, all 3 worked with Lockheed on x-35, 2yrs later Lockheed bought 100 Russian RD-180 closed cycle rocket engines for Lockheed atlas 3/5 and today powers Boeing/ULA Starliner, US engineers were terrible at rockets and vtol that is why they needed help.
You are the best english-speaking channel talking about Su-57 and Su-75. You combine expertise, good observability, willingness to research the topic you're talking about, and most important of all - objectiveness.
А вот тут вы заблуждаетесь... я про объективность! Объективность это не только не предвзятость это совокупность большинства субъективных мнений... ну то есть мнение или точка зрения одного человека априори не может быть объективной! А вот большинство совпадающих мнений и точек зрения и называют объективностью... вот только проблема еще в том что и большинство этих мнений может ошибаться! Простой пример: во времена Джордано Бруно его точка зрения была субъективной а мнение всех остальных объективной... но как показало время... совершенно не верной! Так что ваш довод в сторону объективности здесь совершенно не работает... Мне как человеку живущему в городе где строят самолеты... интересно наблюдать за догадками и ходом мысли автора канала, но пока он в большинстве своих исследований как слепой котенок ищет сиську мамы-кошки... истины в его выводах как молока с кошки... вроде бы и есть, но толку мало! А в некоторых вопросах он не может нас, русских, понять потому что менталитет совершенно другой, он изначально начинает искать или думать в неверном направлении... но из за соображений безопасности моей страны я ничем ему не могу помочь... просто наблюдаю и это забавно!)
Just an addendum: VKS(VVS as that time) always intended the PAK-FA to have "flat" nozzle with *ejector*. the problem with earlier Saturn design patents is it added length and weight that would have shifted the COG further back. The reason why they've only done this now is the availability of large scale metal DMD 3D printers in Russia for mass production. having the nozzle additively manufactured vastly reduces the number of components and they're able to shape the flow such that it minimizes thrust losses. with this comes a reduction in overall length and weight while incorporating an ejector nozzle system giving it 3 air passages for different cruising configuration (this improves its subsonic efficiency for long flights). also, one of the compromises with a less efficient nozzle is heat build up which became a problem with F-22 where its supersonic cruising duration was limited to avoid structural damage in its rear spar between the engines. the ejector also serves as secondary cooling much like in rocket nozzles with hollow bells. aside from the flat nozzle shown, there was another design patent where the nozzle shifts up to form an S bend that completely blocks the turbine from behind. Of course, design is always compromise so it's expected to be used on applications that don't require enormous thrusts. reference picture: www (dot) ausairpower (dot) net/VVS/NPO-Saturn-51_0_sheme_gg (dot) jpg
the reason is that they hit the thrust requirements from the engine to allow them play with different nozzles. and that's why the engine took so long to develop (the one we saw in 2017 was a first stage prototype) in 2024 (7 years later) we get a prototype of the final engine config with the final nozzle
@@tunisiandom9318 there's also the early requirements for PAK-FA to have relatively high cruising speed which led to high dry thrust requirements which would ideally be achieved with the ejector nozzle design. it's really a culmination of everything coming together at this time even though it's kinda late. But yeah, they incrementally added stuff to product 30 which also consequently delayed it. there's also the emergence of photonic radars which would really define the 6th gen features of Su-57M.
"The reason why they've only done this now is the availability of large scale metal sintering 3D printers in Russia for mass production." they already had it many years ago. it's nothing new. also in the quantities they are producing it's no serial production. I'm sorry but that part makes no sense. they could have made it years ago if 3D printing was an issue.
@riskinhos actually, their largest mass production DMD printers were only unveiled this May in St. Petersburg Marine Tech University. Rusmelt series printers were only first made available last year for mass production. What you thinking of are the pilot batches from years ago starting 2014-2016. The main point is the scale of printers. They were only available for 300x300x370mm back then and only getting to 600x600x600mm for commercial printing. What UEC needed ofc is much bigger to fit a 1.28m diameter nozzle as a one piece part which is where DMD comes in. Rosatom's unit that was introduced last year is capable of printing 2.2m diameter with 1m height which also coincides when they made static tests for the nozzle.
su57 is basically one of the most beautiful airframes ever build.....in my opinion a prime example of looks right, flys right.... I mean it looks like the FCS can make it do quite amazing stuff.
Lo mas sorprendente de un avion de 5ta generacion es ver a sus enemigos siempre con suficiente anticipacion para lanzarles 2 o 3 misiles. Las acrobacias son solo para desfiles en la plaza roja
All it has is looks... That's literally the only reason anyone likes it. It's just another Su-27 but they copy-pasted some F-22 in there and then squished it all flat. It is not 5th gen and likely never will be.
@@RedTail1-1 to be devil's advocate, cost of operating F22s is astronomical, any country can invest in RnD to get the latest chips, but that doesn't equate to a combat capable jet fighter. It just further widens the asymmetrical warfare aspect of it. Like Soviet Hinds vs RPGs/Manpads of the mujahedeen hidden in valleys.
@@RedTail1-1 Просто добавили немного F-22, правда считаете, что это просто? А монокристаллические лопатки турбин в российских истребителях, наверное, тоже очень просто :)
I think you missed the part, where the flat nozzle can be moved around, as if it was on an axisymmetrical coupling, which means you only sacrifice thrust, while keeping maneuverability and stealth. plus i think it was said in that video, that the nozzle could be switched out for a circular one and vice versa in the field
@@alpenfoxvideo7255 yes. but this plane is T-50-2 and also the nozzle is a prototype. I would imagine they would change it 50 times over before installing it live
I have said this before and I will repeat it....This is by far the best channel about aviation on youtube and I am advertising it often,suggesting to viewers who are interested about aviation. in fact i did it 20min ago
The flat nozzle will be a lot more stealthy than the round one. Even if you have the sawtooth edges on the round one it still has A LOT bigger RCS than a flat one. Plus the round one must be solid steel to withstand the heat while the flat one has cooling with the vents on the edges meaning you can incorporate some RAM materials to reduce the RCS even further.
It would be really interesting to see the finalised version of the Su-57. It already looks promising with the proposed new helmet, square nozzles, the AL-51 engine which will give the Su-57 its much needed supercruise ability, and perhaps AI? People are never going to stop bashing the Su-57 due to their bias, so we need more of your videos to drown them out.
There is nothing magically wrong with the aircraft. The problem is that doing it right is VERY expensive. The Russian economy was the same size as Italy before the war. The principals of stealth are more widely understood now therefore, the Russians can make to the 57 a great aircraft, as soon as someone pays for it.
@@JosephKlacik According to World Bank, Russian economy is 4th largest 2023, when measured in PPP(only real way to measure economies in different currencies). Secondly, Russian MIC is purpose driven, not profit driven like in US. Third(ly), Russians have all the resources they need to develop industries around avionics, raw materials and STEMs.
@@Tony-cs5hq Russia 5th largest sitting betweeen Germany and Japan in 2022 when it started, now it's 4th slightly ahead of Japan. But considering how they are running a War economy it really doesn't mean much comparing them to big social welfare economy states. It is also WAY below the other economies above it by HUGE margins so it's 4th place is more a technicality. Russia does have the resources to build and develop Industries around avionics materials wise, but it severly lacks in STEMs. Brain Drain is a huge Problem and the Population is aging so more and more experienced Engineers and the like are retireing whilst newer Generations of STEMs are leaving the country in significant amounts (easily 300'000+, many more if they could afford to). This might not be a problem right now but it will be in the future, alongside the War Economy and Russia's spending. Russia will be able to finish the Su-57 but all that know-how is going to get lost considering the huge demographic shift away from russia.
It wasn't that we wanted to see an Su-57 video again. We just wanted to NOT see another fricking video on his bad assessments milking the oreshnik. I unsubbed because he kept milking that instead of staying in his lane and looking at aircraft.
Lol i was thinking of starting with an Su-35 first - my starter fighter jet 😂 Seriously though, the closest we will probably get to flying these beautiful warbirds, will be DCS in VR mode - pretty damn amazing sim.
"i will buy one" Who wouldn't? Just think what kind of performance you could get if you just use it optimised as an aerobatics flier. (as demonstrated at Zhuhai among others)
This is the only channel where i gain some in depth information about foreign jets. Some American channels will dunk on Russian jets and make ridiculous claims on how American jets are 30 years ahead in technology without providing any meaningful facts.
Bro, I thought those flat engine nozzles were fake at first. Yeesh, the SU-57 is turning into something very different than I anticipated. Those angled flat nozzles look really cool vs what you see on the F-22.
Resta comunque inalterata la fama dei Mig 29,31,35 ,arei straodinari di enorme potenza e agilità malgrado alcuni di essi siano piuttosto grandi come il mig 31,una straordinaria evidenza della capacità ingenieristica e progettuale dei russi.😊
The SU 57 is definitely a very interesting fighter and I have a feeling its flaws are being overestimated and its potential underestimated. Great tie/shirt/handkerchief combo by the way!
Look the fact is the Russians are notorious for sensationalizing their military tech. Once the Americans get their hands on any Russian tech, they quickly find its completely mediocre where the claims made about it are nowhere near the truth, and the Americans find themselves having made their own aircraft overkill under the assumption the Russians were being honest about their claims.
It does a lot of the important things of an airframe well, and it does a few things of stealth not so great but quite easily corrected. As for the below par engines, anyone recall the panavia tornado?
I think that the Su-57 is a stop gap measure for the VKS. It may have not started that way, but it seems that the Russians are killing two birds at once: 1) have a complement to the Su-35 and MiG-35 (the latter allegedly being green lighted for larger production runs) 2) Have a potent Design platform for their 6th Gen Aircraft and also the MiG-41! Lastly, Russia is slow rolling the Su-57, because it also needs to have more matured technologies for both its massive drone wingman and the Su-75 Checkmate. I think that in the next 10 years or so, the VKS will be much better positioned that it even been since the mid 80s. This is without them having their wing stealth strategic bomber. I fear that the war, or special military operation in Ukraine, will undoubtedly created a revived and more lethal VKS, which has now seen and tasted some weapons and tactics of NATO in real combat situations.
Its not.. Mig41 its suppose to be show next years. And all info of it point out as substitute for mig31. Su-75 is not in the class of Su-35/Su57 and its more in the line of mig29/mig35 sustitute.
Don't forget that current geopolitical situations heavily dictate the direction of RnD of Government agencies. It's still very possible they'll decide to put this whole project on the bench so they can spend money on things they need right now. Going 6th gen when you don't have mature 5th gen aircraft is going to leave you with a lot of lacking experience and other problems, so they might just decide to focus on getting 5th gen up and running before going for 6th. It's honestly interesting to see what russia is going to do with their money, considering they are currently splashing it everywhere.
The MIG-35 is the new carrier and naval aviation plane it is not for the airforce or army aviation well only the export version might be for either of them but in Russia it is a separate plane for the renewed naval aviation component.
I mean they aren't at all testing against NATO aircraft. The F16 hasn't been delivered to the US Air Force in 20 years. It's a great aircraft but it's not an example of what it would be like to go up against US aircraft. The US does have a lot of F16's still but they are reserve fighters used for things like domestic airspace defense cause they are cheap to operate, used as enemy aircraft in training operations, airshow ponies etc. The US
It’s possible that the entire nozzle is able to rotate (note that the base mounting is still circular). This would achieve full 3D thrust vectoring while preserving the stealth benefits of flat nozzles.
They're angled for a reason. Only 2 of the 4 petals can move. That's why they angled it to achieve 3D vectoring. Otherwise there's no reason to angle them.
@@Shubhabratabanerjee One perfectly good reason would be to avoid revealing the full capabilities of the nozzle. Showing them locked in one unusual position - angled - means they can still talk freely about “3D vectoring” capability without throwing up red flags. This is just hypothetical of course but there are plenty of good reasons why a military would not disclose certain features and capabilities.
Probably worth mentioning that Russia also introduced the new Izd.177S engine in Zhuhai. It does looks like "older" Izd.30 design, with serrated nozzle petals, and probably will be some sort of combination of technologies implemented on both AL-41F1 and AL-51F1. It is intended to be installed on all Flanker models, as well as export versions of Su-57 and Su-75.
Probably using the improvements developed with the -51 yeah. Lighter, stronger, more durable, lower fuel use, and much lower maintenance, that's a lot of very desirable traits if they can make it work well enough.
@nooonanoonung6237 Most likely a replacement for old AL-31 engines, for both domestic (Su-35S, Su-30SM, Su-34) and export Flankers (Su-30MKI, Su-30MK2), without any secret tech used in AL-51.
Recently Indian parliamentary standing committee suggested Indian airforce to get 5th generation aircraft in its fleet on urgent basis. So this might be the reason for SU57 being pitched.
India already had a close relationship with the Su--57. They were originally intending to purchase over 200 airframes, they believed that the PAK FA program had not yielded an aircraft to meet their needs and fully pulled out of the project in 2018. They're now working on their own 5th generation fighter with the AMCA program. It's highly unlikely that India will ever consider the Su-57 again or any Russian aircraft for that matter.
@@BahomaVidyaChannel Exactly. All this hype about SU-57, and even the hope it will finally find an export market, but they completely forget to remember that the primary export market it was meant for, India, already flat out and unconditionally rejected this aircraft.
@@thunderxgod01 The reason India pulled out didn't have that much to do with the jet more to do with everything around it India's main issues with it were Russia's unwillingness to share the technology in the su-57 with India They believe that Russia did not have the ability to produce the SU57 in the numbers and time the they wanted and concerns over the AL41 engines the SU57 is getting a new engine so the AL41 is no longer a problem Russia seems more willing to share technology than they were previously and production may still be a problem but the Su-57 is at least further in its development timeline than before And India's predicament it just got a lot worse than what it was in 2017 now China has hundreds of 5th Gen stealth fighters at least over 300 Pakistan is soon going to receive the J35 given access to 5th Gen fighters and India still doesn't have any if you've seen any reports in Indian media recently they're very positive about the SU57 not only was there the parliamentary investigation recommending the purchase of the Su-57 but there was also a Indian general who recommended it India purchasing the SU57 really does not seem that far fetched.
Have you ever looked at the Embraer Super Tucano? I know it's development goes back 30 years but a lot of people only want to talk about the best and most expensive but taking a look at practical mission scope and developing affordable solutions seems to be an innovation in itself for combat aircraft and something that no one else is doing.
If you look closely at the video excerpt with the changing size of the nozzle, you can see that the nozzle does not just open the flaps, they move apart, while maintaining the parallelism of the flaps. This design not only changes the diameter of the outlet, increasing or decreasing the gas flow, but also shifts the center of the force vector relative to the longitudinal axis of the engine. A very interesting and unusual idea.
О каких недостатках средств у России вы пишите? Вы серьёзно? Прежде чем писать глупость, почитайте об экономическом росте, приведённые хотя бы данными МВФ.
That has always be the case. Mig1.44 was a monster of plane but too expansive. In Tank its also the same. Obj187 was an amazing tank. But they end using T-90 because it was cheaper.
I recall reading way back before the 2008 US housing crisis that BAE was developing thrust vectoring nozzles for the Eurofighter. The project was cancelled due to the economic turmoil at the time but they said that despite making the engines heavier and thus the aircraft also but that the control of the engine exhaust more than compensated for the weight gain and improved the plane's performance. Could be one reason why Russia likes to use thrust vectoring in it's planes.
They also realized that the rear part of the Eurofighter fuselage would be very prone to cracking in several places… there were never any funds released to deal with that.
Due to the flat slider segments, the angle in which the thrust can be directed increases largely while at the same time, the actual nozzle has not to be moved that much.
The nozzle seemed to have better movement than the F22 2d vector. It looks like they have developed a 3d vectoring probably a little more limited in movement than the 41. But of you have more thrust it should compensate for the slight loss in movement. The flat nozzle and limiting the IR is needed for a dogfighter. As most Fox2 are IR missles. You already beat the fox 4s for eith reduced signature and mobility.
It makes sense. It was already overpowered, and now they get a 20% thrust increase with AL51F... It is one of the rare occasions where stealth is more pragmatic, as it reduces maintenance and simplifies the design at a slight cost of >0.95x1.2 = >14% more thrust than now. At some point one could ask, what should be done with all the excess thrust? Well, here we see one answer. And the potential loss of the flat nozzle is *up to* 5%, so it's very marginal. Also interesting how the new and more powerful engine is also easier to maintain than the older one.
4:33 Ehhh we do know what such features will be , infact it has been stated by Sukhoi. Those features are centered around network centric warfare / drone wingman and AI. Drone wingman has already been tested on Su-57 and it is safe assumption that it will become a standard feature on Su-57M .
In aviation design there is rarely stupid things done, without actual thinking the compromised factors. When an aircraft is designed, it is done for specific tasking and it rules everything. One can't make a perfect aircraft for everything, there comes some compromises for something. Question is just that is the compromises shifted to some other area that are not meant to be performed by the given airframe, hence is it such mission capable or not. There are lot of new challenges that are seeked for and searched solutions. It requires research and development time. And sometimes it is just better to start production with current design, and then later on come up with the new variant that improves or changes something that was known to be needed be changed. Great example is the Su-27 as in T-10-1, that was transformed to something totally new for the Su-27S, the first serial production, from T-10-1 to T-10S-1. A major redesign in very early prototyping phase that then was started later on, years later. Similar is with F-35, and before that the F-22 that is limited to its existing problems as it is not in production for long time so no fixes there. And before that the F-16 that has been altered to completely different performing aircraft, sacrificing the original design benefits with designed restrictions that was to stop F-16 becoming what it became. Sukhoi has nice addition with the Su-75 to get more freedom to seek other objectives that Su-57 can't be changed anymore.
Millennium 7, If you watch the video (The Lord of the Sky), at 8:37 you can hear the main Su-57 designer say "Since the angle of installation is kept the same it was on the axisymmetric nozzle (!!!) all supermaneuverability capabilities are preserved" No RuAF fighter has 3d thrust vectoring, that's simply unnecessary since the slanted differential deflection gives pretty much the same moments as one 3D TVC nozzle. Moreover, that's confirmed by the pilots who fly the Su-35S
Well it is not exactly the same some loss will be there from the different shaped nozzle but about 90% of the freedom of movement is maintained and the extra 40% thrust will do the other 10%.
@@xanovaria Ok sure fine you believe the 30 billion dollars propaganda global news machine that alla of them say the same things at exactly the same time and we know for sure that that 60% is either fake or half truth news. We read and research papers and documents from every country first then make formulated assumptions we know nothing for sure, based on science ,past experiences as part of the army and air force and video evidence only not on bribes ,feelings personal opinions and agendas.
The big fan looking thing in the back appears to be a simple de-swirling vane. I believe it's purpose is to stop the swirl of the air leaving the turbine so that it exits the engine axially. It might have some stealth characteristics designed into it, but I don't believe stealth is it's primary purpose.
As a Russian viewer, I am amazed at how biased you are. The Su-57 has never proven supercruise, has never accelerated above Mach 1.4, has never fired its onboard cannon in flight, and has never had 3D deflectable nozzles. The "Grom" guided bomb has no evidence of use or even existence. Even if it exists, its design makes no sense. The rest of the air-to-ground guided weapons consist of a prototype stealth cruise missile. That's all. No smart bombs fit in the bay, because the Russian equivalent of the JDAM is the bulky and outdated UMPK. According to UAC, more than 40 aircraft have already been delivered, and the VKS has not announced even one squadron. Not a single squadron has been formed. You always talk about bolts and crooked panels on the prototype aircraft, but where is the photo evidence that the production models have a normal RAM? So far, all photos of "production" models do not differ from the prototype in terms of coating. Please, find more authoritative sources of information for your videos.
@Millennium7HistoryTech I've been sitting on Russian aviation forums for 10 years, and you haven't. I read Russian news, and you don't. Find refutations of what I wrote. In principle, I understand why you do this. You're tired of stupid Western bloggers who make clickbait for Western normies. But now you make videos for Western normies, only for others. For "not like everyone else" normies.
To be honest, USA is so desperate to sell its aircraft. I feel it will get in talks with India with the offer of the F 35 too and try to find a reasonable deal where India gets full and unconditional support unlike Russia, which promises complete technology transfer full support and the permission to modify the aircraft which the Americans would never not even to their closest allies, except Israel and that too only software and internal hardware not the structure itself. It would be very difficult for the United States to match what Russia is offering currently both are desperate for market of India and India as a desperate customer with fifth generation threats potentially on all of its borders
Allow me to say my own 57 cents about the nozzles: as always when Russians are involved I would adopt an AND/AND instead an OR/OR one approach. We know that they were always poised to adopt the Al-51F1 as their own definitive engine so that they didn't just bothered to develop a serrated nozzle for the 30/40 planes they would adopt with the interim one (but they have presented such one for their legacy Al-31F instead), so now that the new one with round exhaust is ready they would complete the actual order with such ones and keep on to developing the squared one. Once that their own development would be near completion their would evaluate both of them for the Su-57M and successive planes they would adopt, beginning with the ones that will come out from the Su-75 (as this one is not an official VKS designation) private enterprìse program and the two seated Felon they have already announced they would use as a drone air controller.
The Su-57 is stunning and futuristic looking! With angular stealthy lines and a cockpit optimized for maximum pilot visibility, it screams dominance and innovation. AND it has AI! Damn!
A MINOR corrections. The Russians did not say that this flat nozzle is going to be standard on the new engines/planes. They said they needed to develop this just as an option and as well as for international customers of Su-75/57, if they will want it. So the designers did not really change their stance that higher manoeuvrability and resulting thrust is in general better for Russia.
india really wants the 2 seater option. loyal wingman and other drone control is just too much for 1 person in a battle space. if india takes this up, i expect 1st batch of 1 seaters and then a 2nd batch of 2 seaters. vietnam could be interested but see the su75 as being more a fit for them. argentina would like the su75 but the US is shutting that door with a recent sale of f16s.
argentina cant afford su57. su75 on the other hand maybe. it all depends on new engines and how expensive will be to maintain. su75 could sell very very well as its the only (besides f35) single engine 5th gen fighter. also vietnam will probably want su75 just ability to buy more. and india who knows. maybe they are giving up on their own aircraft or know it wont fly for the next 20 years so they really want something right now.
Vietnam also needs big aircrafts for maritime patrol. Su-27/30 usually fulfills this role. The 90s' Su-27 are reaching end-of-life, they want to replace them with Su-57 or Su-35 and create new units with Su-75.
It's pretty much a trade-off between power(and efficiency) and stealth. It sacrifice a bit of power of the engine for thermal and radar stealthiness. It still has 3D vectoring though so it's still good.
How are those many variations of angles and movements being chosen and controlled? By pilot choosing a certain set of nozzle movements or does the computer chose the right package without the pilots input? It seems that specifically Russian jets have a multitude of possibilities.
computer chose all outputs since 1980s, its reading inputs from pilot + environment and adjust it to preprogrammed maneuvers, pilot basicaly only have to contol scale of maneuvering
Excellent video as usual. I'm thinking maybe they will use both nozzles. The flat ones can be used for Su-57s tasked with penetrating airspace, while the round ones can still be used for those tasked with defensive operations.
You can never have to many videos on the best all around 5th generation fighter in world in my opinion. Thanks for another great video. The SU-57's nozzles are not completely rectangular and far less restrictive of the thrust coming from the engine. We can also see that the exit part of the nozzle of the AL-51F1 is not flat, like the one on the F-22 nozzle, but it is angled making it closer to a circular shape, which probably results in less thrust loss, since the plume is not going from the circular to totally rectangular shape like in the case of the Raptors nozzle.
It might be a nozzle for missions that don't require particular maneuverability, thus the aircraft can do whatever it has to do without having to spend so much on maintenance, while the 3d one isn't scrapped but is just used in other cases...
I don't understand the American air combat doctrine that super maneuverability is not particularly useful in modern air combat... even if they believed that BVR spamming of missiles is the be-all and end-all of air combat now, those missiles still have a limited range and kinetic ability that can be exploited (and defeated) by deft maneuvering? Just watch that Russian pilot who did that crazy haul-ass flying when he had like 3 or 4 patriots launched against him and hunting him down. Surely increased maneuvering means increased survivability? What are we missing here?
@@scroopynooperz9051 Super maneuverability is only useful in gun only dogfights tbf, because evading bvr missiles requires speed which supermaneuverability trades for being able to spin around your nose to any position you want. To kinetically defeat missiles you need speed, that's why US weeaboos always talk how useless it is. But it has it's uses outside of battle too, you're less likely to lose your plane to a flat spin or any other difficult situation, so it's quite good in that aspect. That said, having that advantage is like that anecdote about soldiers that fight with a knife: "to have a knife fight you have to not have your ammo, your rifle, your pistol, your grenades, and then you have to find an enemy soldier that's just like you"
That is the central hub of the turbine. It has no place for afterburner there. And no radar shading or cold air mixing. (maybe mixing is done in the previous turbine stage) In B2 & F117, the engine is buried deep in the body, totally masking the turbine and compressor blades from radar signals. also the long exhaust provides enough time for heat dissipation and cold air mixing. - To some degree F-22 also has that feature. F-35 does not have.
This is how the engines were laid out on Rockwell's ATF proposal. Not that mini B-1 looking thing, their actual proposal, it had angled square exhaust nozzles. As I heard it, they did that so they could use a corner of the engine as a narrow corner to match with RCS shaping.
@nickbrough8335 Australia as a start! Israel realises that during the last air campaign they tried to mount with the flying Barn doors, aka F35s, against Iran, they were detected at least 100kms from the border! TBH, even Elon Musk has finally realised that the entire F35 project is a huge scam. Google it! I'm pretty sure all US allies have realised that they've made a huge mistake partnering the USA.

It's good there is diversity; gives some colour to society. I absolutely hate russia - in all aspects; I used to work with russians. Yet I still admire the beauty of this su-57.
I think the flat nozzle provides more benefit than more granular thrust vectoring? What good is maneuvering if you're seen from miles away just cause of heat? Anyone who says it's a down grade is insane? But for the Russians to maintain the flat nozzle and be able to articulate the entire nozzle around to b include the extra dimension of geometry is actually genius thinking! I think that is the most innovative part of all of this, and perhaps that should be emphasized more in the decision? They haven't lost anything by going back to the flat nozzle because they overcome the flat nozzles shortcomings of limited dimensional movement; they also deleted articulation of the side flaps removing a major source of potential fault l failure.....I will presume that the rotational articulation of the nozzle will be designed around a ring gear on a barrel so to speak, meaning that the electronics and mechanical components will be shielded from heat. The US uses linkages on the jet side flaps to remotely articulate those small side flaps, but those linkages are subject to the most intense heat and conducting of heat is unavoidable creating a new source to mask or keep cool. By maintaining the flat 2D control vectoring and substituting by rolling the entire nozzle will provide much more granulator control especially for telemetry and future automated control of systems? For instance individual articulation between the 2 jets could assist in tighter rolls or maneuvers especially if machine learning from pilot data? There could be instances where AI can optimise the thrust vectoring to assist the pilot? I'm waiting to see if we get more monowing vector shapes in next generation air craft that integrate the jet engines more inboard so that the heat signature is more masked by control surfaces such as vertical stabilisers or V tail designs and using more aerospace ceramics to mitigate radiant heat propogation? To put simply that with speed and pulsejet propulsion on the horizon that the typical jet and high-speed maneuverability becomes a low priority over top speed performance. At least the with the flat nozzle design factor allows for "potential" future proofing the air frame, however I think the Russians are more likely to do a complete design shift when they declare their air craft of designated generation? The Russians will like to make a clear distinction between what they consider 4th 5th or 6th generation where America has become wishy washy especially with the blending of 4th to 5th, but i think the confusion is a strategic thing also but who really knows? I'm not pro anything but I'll acknowledge if I think something is a wise decision or not? In my opinion this shift is a wise decision but I'm no military expert, it just makes sense to me scientifically? It's physics. There are also marked times in history where the logic in design makes sense to the physics equations but in reality we discover otherwise or we discover new phenomena at play that wasnt accounted for whilst modelling etc? All kinds of things can go against logic. But scientific process is not about success of 6 failure it's about testing the hypothesis and it's those things that fill in the counter intuitive hypothetical blanks that creates innovation. Logic now says that you shouldn't go so far down a design path that traps you when something revolutionary happens in engineering....... You keep your opinion open for as long as possible. Plasma is the next state of matter that humanity will harness for transmutation of materials and that's when we will see a completely new science arrive. I can't wait for that to occur!
If you look closely in the first video it appears the nozzles also rotate, in the last still photo the nozzle is rotated to the left of the centre axis. ? The still photos also seems to show a barrel joint which would allow this rotation !
Wake up babe, Millennium uploaded another Su-57 Felon video. Jokes aside, I like the Su-57 over the F-22. Hope it gets the good avionics aka stealth feats in the future. Flat nozzles looks dope!
Flat nozzles that can rotate in 180 degree arcs before pitching seem like the ideal. Engineering that would be the clever part. (Just interacting to help the channel, here.)
One obvious advantage Russia has is their availability to titanium which is a very important component in high temperature engine components. The new redesign of the SU-57 engine nozzle (to increase steal profile) a logical move. India's renewed interest in the (now combat proven..) SU-57 is also quite understandable.
You keep asking yourself why they do this ?! Here are a few simple answers : The Americans constantly comparing the 2D exhaust of the F-22 Raptor with 3D exhaust an they said that the 3D vectored exhausts like the ones they tried on the F-16 VISTA have a smaller angle of deflection of, say, 23 degrees, while the 2D exhaust has up to 28 degrees; The Americans also argued that the Russian 3D exhausts have too large an infrared reflection and can be easily tracked by advanced IC cameras; this new form of 3D exhaust should have a stealth shape with a reduced infrared trace that interferes with IC camera tracking; ionization of the exhaust with negative ions can allegedly further reduce IC reflection because negative ions in the air increase the absorption of O2 molecules into the cells of living beings, dissolved O2 is precisely reduced when heating water and air, which leads to the creation of positive ions that are fought against by negative ions; so the negative ions somehow restore the normal properties of the unheated molecules of the atmosphere even though they are heated and bring them to a state before that, which can reduce the IC reflection; this form of 3D exhaust is what I would call an aerodynamically unstable "3D" vectored exhaust which can further increase maneuverability in air combat and attempts to avoid missiles fired at this aircraft. I thought about such exhausts and very similar ones more than 10 years ago and now I have consolations that are decades ahead of this solution. In any case, the Russians are showing the Americans that they can correct what the Americans rightly criticized.
I think it's unnecessary if it tries to reduce radar section from the back if the thrust loss is anything above 10%. Does the AL 51 have more thrust with the loss of square nozzles against an AL 41 with round nozzles? If yes then it might be ok, but only if the Su 57 is capable of supercruise with these nozzles. the Su 57 already showed its stealth capability when it was flying above the frontline at 5000+ meters of altitude when it shot down the S-70 drone after it lost control over it. Any other jet would have been shot down by patriots before it could even get to the front line at such altitude.
The fact that the Russian Ministry of Defense does not want more Su-57s with AL-41s does not mean that they will stop producing them right away. Contracted aircraft with old engines will be produced for another two to three years.
To be fair, the al-41f1s (su-35) never had an a 3d thrust vectoring nozzle. The 3d effect was achieved by tilting the engines along the axis and a certain distance between them, which made it possible to transmit the yaw moment of force. On most of the Su-30 this is also implemented, with the exception of those vehicles that came with Salyut engines that deflect the flow of the supersonic part of the jet stream. On the al-41f1 (su-57) everything is most likely done the same. Apparently, this solution is optimal for twin-engine machines in terms of simplicity, weight, reliability and ease of maintenance. With this flat nozzle, judging by the same inclination, the story will be the same. So in this situation, the choice between a flat and a round nozzle will be a choice between a little more stealth and a little less thrust, and vice versa.
The angled position of the nozzles (2.5D) on the SU 30 MKI is not limited to India as a customer, but a common part of that SU30 MK version used by many other customers, including the Russian airforce in their Su 30SM. Since that Su 30 version is produced in larger numbers than the Su35, that type of nozzle is actually more common than the 3D TVN in the limited number of SU35s that are available. Wrt the loss of manouverability, one has to keep in mind, that unlike the Su35 or the F22, the Su57 has additional LEVCONS and is not limited to the TVNs alone to improve it's turning ability. Going for the more common Su 30MK system, but in an improved version that also seems to be way more beneficial in terms of IR reduction and propably costs, without losing too much in terms of manouverability seems the sensible solution. But then the question must be, why only now and not 10 years ago?
The reason is , india pulled out of joint development project and russia doesn't have money to develop.. all these changes to to impress indian to invest in the program. Indian airforce had identified 52 shortcomings., one of those were round nozzles.
@nighthawk4028 Common misconception especially in the west, the reality was very different. India simply didn't had the money to go for the special version they wanted intially, so they continuesly cut down on their own requirements and numbers within that joint programme, to the point that under the new govt not even sufficient numbers of legacy fighters were procured, let alone NG fighters. The govt hides that lack of funding today, with the claim to support Indian projects, because that delays any costly procument for years. IAF is not allowed to buy even the first Su57 in any useful numbers, simply because it's costly to procure and operate, while there is no funding available.
A thought crossed my mind. They are working on the PD-35 engine with composite fans. What if the 3 LP fans of the AL-51F1 is composite as well? That would potentially reduce RCS.
It makes sense to me... The SU-57 needs better nozzles if it wants "stealth". Thrust and maneuverability are 4th gen focuses that aren't used often when "stealth" is necessary.
Considering how much easier the serrated Low Observable Asymmetric Nozzle (LOAN) of the F-35 are to make and how effective they are I am also rather confused why they would opt to go with the Flat Nozzles. Still they look very cool on the Felon. A most informative video as always.
These aircraft share a single modular platform. This allows for faster production and easier service. The Russian aircraft are also characterised by an open weapons architecture. Each customer can build its own aircraft, for its own armament, without any prohibitions. Thus, the customer will protect himself in the future. It has long been known that the USA imposes sanctions on its partners and thus the purchased planes are transformed into ground museums, new parts cannot be obtained for them and weapons cannot be used.

People don't realize Russia were the first nation to implement flat nozzles on there 1970's vtol yak-38/41 program, only for testing purposes of thrust vectoring are they mentioned, Quote from yakovlev:
"a flat two-axis nozzle was designed in the second half of the 1970s for the Yak-41 vertical take-off and landing (VTOL) deck fighter. An original solution was used for its rotation - the nozzle was divided into three segments, which, rotating in opposite directions relative to each other, provided a deflection of the thrust vector in the vertical plane to an angle of 95° (at VTOL mode). For short takeoffs, the nozzle was set to 62°. This solution made it possible to use afterburner both in horizontal flight and in vertical mode"
@@paulroberts7429 yes but because of the geopolitical rivalry that persists to this day, technological innovation spearheaded by Russians (or the USSR of old) is evidently not allowed to be celebrated or even acknowledged 😂

Timmy: "Well, didnt Lockheed Martin get some F-35 homework from the Soviet Yak-41 program? They got all the blueprints when the USSR collapsed."
Jerry: "Wait.. what?"
@@scroopynooperz9051 A couple of problems with the suggestion that the F-35 copied anything from the Yak-41.
First, like its predecessor, the 41 had two small vertically mounted jet engines behind the cockpit to provide vertical lift. The idea of sticking vertical engines in the airframe to provide takeoff and landing lift was well known by everybody - it just wasn't used much because the problems it introduced nullified the benefits. The F-35's lift fan brings fewer problems with it and even solves a big problem that previous VTOL fighters - including the Yaks - had.
Second, work on what would eventually be called the JSF program actually started way back in 1983 when the USMC approached DARPA for a supersonic, stealthy replacement for the Harrier. Lockheed's Skunk Works were already developing the required technologies when DARPA awarded them a classified contract in 1987, four years before Lockheed started cooperating with Yakovlev.
@@scroopynooperz9051man I thought the name Jerry was reserved for the Germans.
Also Yak 41 might have been inspiration for the F-35 but that’s it, Yak 41 has a completely different system to vtol, and no stealth implementation, or the kind of tech that the F35 has.
So when you say the Americans copied it you are literally just saying that because that’s what you want to believe.
Then purchased by Lockheed Martin for use in the F-35 program, no this is not an internet conspiracy. All data and some production pieces all exported legally years before the deep state made Russia the Pariah the complex needs to get it's funding. The JSF may have started work in the 80's but you do NOT pass up the opportunity to get your hands on all that research data, production pieces and potentially a couple of prototype examples of the Yak-41.

@@maxv1455 Демагогия)
Just an addendum: VKS(VVS as that time) always intended the PAK-FA to have "flat" nozzle with *ejector*. the problem with earlier Saturn design patents is it added length and weight that would have shifted the COG further back. The reason why they've only done this now is the availability of large scale metal DMD 3D printers in Russia for mass production. having the nozzle additively manufactured vastly reduces the number of components and they're able to shape the flow such that it minimizes thrust losses. with this comes a reduction in overall length and weight while incorporating an ejector nozzle system giving it 3 air passages for different cruising configuration (this improves its subsonic efficiency for long flights). also, one of the compromises with a less efficient nozzle is heat build up which became a problem with F-22 where its supersonic cruising duration was limited to avoid structural damage in its rear spar between the engines. the ejector also serves as secondary cooling much like in rocket nozzles with hollow bells.
aside from the flat nozzle shown, there was another design patent where the nozzle shifts up to form an S bend that completely blocks the turbine from behind. Of course, design is always compromise so it's expected to be used on applications that don't require enormous thrusts.
reference picture: www (dot) ausairpower (dot) net/VVS/NPO-Saturn-51_0_sheme_gg (dot) jpg
the reason is that they hit the thrust requirements from the engine to allow them play with different nozzles.
and that's why the engine took so long to develop (the one we saw in 2017 was a first stage prototype)
in 2024 (7 years later) we get a prototype of the final engine config with the final nozzle
@@tunisiandom9318 there's also the early requirements for PAK-FA to have relatively high cruising speed which led to high dry thrust requirements which would ideally be achieved with the ejector nozzle design. it's really a culmination of everything coming together at this time even though it's kinda late. But yeah, they incrementally added stuff to product 30 which also consequently delayed it.
there's also the emergence of photonic radars which would really define the 6th gen features of Su-57M.
"The reason why they've only done this now is the availability of large scale metal sintering 3D printers in Russia for mass production." they already had it many years ago. it's nothing new. also in the quantities they are producing it's no serial production. I'm sorry but that part makes no sense. they could have made it years ago if 3D printing was an issue.
@riskinhos actually, their largest mass production DMD printers were only unveiled this May in St. Petersburg Marine Tech University. Rusmelt series printers were only first made available last year for mass production. What you thinking of are the pilot batches from years ago starting 2014-2016.
The main point is the scale of printers. They were only available for 300x300x370mm back then and only getting to 600x600x600mm for commercial printing. What UEC needed ofc is much bigger to fit a 1.28m diameter nozzle as a one piece part which is where DMD comes in. Rosatom's unit that was introduced last year is capable of printing 2.2m diameter with 1m height which also coincides when they made static tests for the nozzle.

I think you missed the part, where the flat nozzle can be moved around, as if it was on an axisymmetrical coupling, which means you only sacrifice thrust, while keeping maneuverability and stealth. plus i think it was said in that video, that the nozzle could be switched out for a circular one and vice versa in the field
Is there any evidence of that? The footage I've seen doesn't show any rotation of the nozzle.
At this time the nozzle installed on the real plane totally lacks the ball-mount that was in that 3D rendering. Also missing from the leaked drawings.

The flat nozzle will be a lot more stealthy than the round one. Even if you have the sawtooth edges on the round one it still has A LOT bigger RCS than a flat one.
Plus the round one must be solid steel to withstand the heat while the flat one has cooling with the vents on the edges meaning you can incorporate some RAM materials to reduce the RCS even further.

It may have not started that way, but it seems that the Russians are killing two birds at once: 1) have a complement to the Su-35 and MiG-35 (the latter allegedly being green lighted for larger production runs) 2) Have a potent Design platform for their 6th Gen Aircraft and also the MiG-41!
Lastly, Russia is slow rolling the Su-57, because it also needs to have more matured technologies for both its massive drone wingman and the Su-75 Checkmate. I think that in the next 10 years or so, the VKS will be much better positioned that it even been since the mid 80s. This is without them having their wing stealth strategic bomber.
I fear that the war, or special military operation in Ukraine, will undoubtedly created a revived and more lethal VKS, which has now seen and tasted some weapons and tactics of NATO in real combat situations.
Its not.. Mig41 its suppose to be show next years. And all info of it point out as substitute for mig31. Su-75 is not in the class of Su-35/Su57 and its more in the line of mig29/mig35 sustitute.
Don't forget that current geopolitical situations heavily dictate the direction of RnD of Government agencies. It's still very possible they'll decide to put this whole project on the bench so they can spend money on things they need right now. Going 6th gen when you don't have mature 5th gen aircraft is going to leave you with a lot of lacking experience and other problems, so they might just decide to focus on getting 5th gen up and running before going for 6th. It's honestly interesting to see what russia is going to do with their money, considering they are currently splashing it everywhere.
The MIG-35 is the new carrier and naval aviation plane it is not for the airforce or army aviation well only the export version might be for either of them but in Russia it is a separate plane for the renewed naval aviation component.
I mean they aren't at all testing against NATO aircraft. The F16 hasn't been delivered to the US Air Force in 20 years. It's a great aircraft but it's not an example of what it would be like to go up against US aircraft. The US does have a lot of F16's still but they are reserve fighters used for things like domestic airspace defense cause they are cheap to operate, used as enemy aircraft in training operations, airshow ponies etc. The US
The more videos about su-57, the better ... Whenever I watch your videos, I learn something new about avionics. ❤
It’s possible that the entire nozzle is able to rotate (note that the base mounting is still circular). This would achieve full 3D thrust vectoring while preserving the stealth benefits of flat nozzles.
They're angled for a reason.
Only 2 of the 4 petals can move. That's why they angled it to achieve 3D vectoring. Otherwise there's no reason to angle them.
@@Shubhabratabanerjee One perfectly good reason would be to avoid revealing the full capabilities of the nozzle. Showing them locked in one unusual position - angled - means they can still talk freely about “3D vectoring” capability without throwing up red flags.
This is just hypothetical of course but there are plenty of good reasons why a military would not disclose certain features and capabilities.
I like that you decided to take the overture 1812 for that short clip :)
Agree, excellent choice!
Whatever politics aside, Russian history is quite interesting, a country with much beauty and majesty.
Probably worth mentioning that Russia also introduced the new Izd.177S engine in Zhuhai. It does looks like "older" Izd.30 design, with serrated nozzle petals, and probably will be some sort of combination of technologies implemented on both AL-41F1 and AL-51F1. It is intended to be installed on all Flanker models, as well as export versions of Su-57 and Su-75.
Probably using the improvements developed with the -51 yeah.
Lighter, stronger, more durable, lower fuel use, and much lower maintenance, that's a lot of very desirable traits if they can make it work well enough.
The 177s is the export version of all SU-35 and especially the SU-75 ,SU- 57 and SU-70 strategic combat drone systems
Lower perf. for longer service cycles compared to domestic engines?
@nooonanoonung6237 Most likely a replacement for old AL-31 engines, for both domestic (Su-35S, Su-30SM, Su-34) and export Flankers (Su-30MKI, Su-30MK2), without any secret tech used in AL-51.
Recently Indian parliamentary standing committee suggested Indian airforce to get 5th generation aircraft in its fleet on urgent basis.
So this might be the reason for SU57 being pitched.
in 2050 India will buy
India already had a close relationship with the Su--57.
They were originally intending to purchase over 200 airframes, they believed that the PAK FA program had not yielded an aircraft to meet their needs and fully pulled out of the project in 2018. They're now working on their own 5th generation fighter with the AMCA program.
It's highly unlikely that India will ever consider the Su-57 again or any Russian aircraft for that matter.
@BahomaVidyaChannel India is country which can only beg.
@@BahomaVidyaChannel Exactly. All this hype about SU-57, and even the hope it will finally find an export market, but they completely forget to remember that the primary export market it was meant for, India, already flat out and unconditionally rejected this aircraft.
@@thunderxgod01 The reason India pulled out didn't have that much to do with the jet more to do with everything around it India's main issues with it were Russia's unwillingness to share the technology in the su-57 with India They believe that Russia did not have the ability to produce the SU57 in the numbers and time the they wanted and concerns over the AL41 engines the SU57 is getting a new engine so the AL41 is no longer a problem Russia seems more willing to share technology than they were previously and production may still be a problem but the Su-57 is at least further in its development timeline than before And India's predicament it just got a lot worse than what it was in 2017 now China has hundreds of 5th Gen stealth fighters at least over 300 Pakistan is soon going to receive the J35 given access to 5th Gen fighters and India still doesn't have any if you've seen any reports in Indian media recently they're very positive about the SU57 not only was there the parliamentary investigation recommending the purchase of the Su-57 but there was also a Indian general who recommended it India purchasing the SU57 really does not seem that far fetched.
Thanks!
Thank you to you!
Have you ever looked at the Embraer Super Tucano?
I know it's development goes back 30 years but a lot of people only want to talk about the best and most expensive but taking a look at practical mission scope and developing affordable solutions seems to be an innovation in itself for combat aircraft and something that no one else is doing.
The Gripen is famous for being cheaper than the previous generation of fighters, and unique in that aspect.
If you look closely at the video excerpt with the changing size of the nozzle, you can see that the nozzle does not just open the flaps, they move apart, while maintaining the parallelism of the flaps. This design not only changes the diameter of the outlet, increasing or decreasing the gas flow, but also shifts the center of the force vector relative to the longitudinal axis of the engine. A very interesting and unusual idea.
These sophisticated design proves that Russian do posses great ability but lack funds are preventing them to develop greater technologies.
And also corruption
О каких недостатках средств у России вы пишите? Вы серьёзно? Прежде чем писать глупость, почитайте об экономическом росте, приведённые хотя бы данными МВФ.
Расскажи это русским гиперзвуковым ракетам) или лучше американским гиперзвуковым ракетам😂 которых нет
@@EmaSuryani-f1iI wonder who is _really_ corrupt? 🤔. ....yes, it's our favourite little foe, 🇺🇸 !!
That has always be the case. Mig1.44 was a monster of plane but too expansive. In Tank its also the same. Obj187 was an amazing tank. But they end using T-90 because it was cheaper.
I recall reading way back before the 2008 US housing crisis that BAE was developing thrust vectoring nozzles for the Eurofighter.
The project was cancelled due to the economic turmoil at the time but they said that despite making the engines heavier and thus the aircraft also but that the control of the engine exhaust more than compensated for the weight gain and improved the plane's performance.
Could be one reason why Russia likes to use thrust vectoring in it's planes.
They also seem to think dogfights are going to win 21st century air battles
They also realized that the rear part of the Eurofighter fuselage would be very prone to cracking in several places… there were never any funds released to deal with that.
Love the SU-57! ❤
Due to the flat slider segments, the angle in which the thrust can be directed increases largely while at the same time, the actual nozzle has not to be moved that much.
The nozzle seemed to have better movement than the F22 2d vector. It looks like they have developed a 3d vectoring probably a little more limited in movement than the 41. But of you have more thrust it should compensate for the slight loss in movement. The flat nozzle and limiting the IR is needed for a dogfighter. As most Fox2 are IR missles. You already beat the fox 4s for eith reduced signature and mobility.
Terribly written. Try again?
Let's be honest. RU wanted a flat nozzle because the Americans have a flat nozzle on the F-22.
RU has been bashing flat nozzles since the F-22 showed up, now they are doing it lol
It makes sense. It was already overpowered, and now they get a 20% thrust increase with AL51F... It is one of the rare occasions where stealth is more pragmatic, as it reduces maintenance and simplifies the design at a slight cost of >0.95x1.2 = >14% more thrust than now.
At some point one could ask, what should be done with all the excess thrust? Well, here we see one answer. And the potential loss of the flat nozzle is *up to* 5%, so it's very marginal.
Also interesting how the new and more powerful engine is also easier to maintain than the older one.
4:33 Ehhh we do know what such features will be , infact it has been stated by Sukhoi. Those features are centered around network centric warfare / drone wingman and AI. Drone wingman has already been tested on Su-57 and it is safe assumption that it will become a standard feature on Su-57M .
In aviation design there is rarely stupid things done, without actual thinking the compromised factors.
When an aircraft is designed, it is done for specific tasking and it rules everything. One can't make a perfect aircraft for everything, there comes some compromises for something. Question is just that is the compromises shifted to some other area that are not meant to be performed by the given airframe, hence is it such mission capable or not.
There are lot of new challenges that are seeked for and searched solutions. It requires research and development time. And sometimes it is just better to start production with current design, and then later on come up with the new variant that improves or changes something that was known to be needed be changed.
Great example is the Su-27 as in T-10-1, that was transformed to something totally new for the Su-27S, the first serial production, from T-10-1 to T-10S-1.
A major redesign in very early prototyping phase that then was started later on, years later.
Similar is with F-35, and before that the F-22 that is limited to its existing problems as it is not in production for long time so no fixes there. And before that the F-16 that has been altered to completely different performing aircraft, sacrificing the original design benefits with designed restrictions that was to stop F-16 becoming what it became.
Sukhoi has nice addition with the Su-75 to get more freedom to seek other objectives that Su-57 can't be changed anymore.
Millennium 7, If you watch the video (The Lord of the Sky), at 8:37 you can hear the main Su-57 designer say "Since the angle of installation is kept the same it was on the axisymmetric nozzle (!!!) all supermaneuverability capabilities are preserved"
No RuAF fighter has 3d thrust vectoring, that's simply unnecessary since the slanted differential deflection gives pretty much the same moments as one 3D TVC nozzle. Moreover, that's confirmed by the pilots who fly the Su-35S
Well it is not exactly the same some loss will be there from the different shaped nozzle but about 90% of the freedom of movement is maintained and the extra 40% thrust will do the other 10%.
Believing anything RU says is a stretch.
@@xanovaria Ok sure fine you believe the 30 billion dollars propaganda global news machine that alla of them say the same things at exactly the same time and we know for sure that that 60% is either fake or half truth news. We read and research papers and documents from every country first then make formulated assumptions we know nothing for sure, based on science ,past experiences as part of the army and air force and video evidence only not on bribes ,feelings personal opinions and agendas.
The big fan looking thing in the back appears to be a simple de-swirling vane. I believe it's purpose is to stop the swirl of the air leaving the turbine so that it exits the engine axially. It might have some stealth characteristics designed into it, but I don't believe stealth is it's primary purpose.
At last at least one wise western technologist showing correct map
As a Russian viewer, I am amazed at how biased you are.
The Su-57 has never proven supercruise, has never accelerated above Mach 1.4, has never fired its onboard cannon in flight, and has never had 3D deflectable nozzles.
The "Grom" guided bomb has no evidence of use or even existence. Even if it exists, its design makes no sense. The rest of the air-to-ground guided weapons consist of a prototype stealth cruise missile. That's all. No smart bombs fit in the bay, because the Russian equivalent of the JDAM is the bulky and outdated UMPK.
According to UAC, more than 40 aircraft have already been delivered, and the VKS has not announced even one squadron. Not a single squadron has been formed.
You always talk about bolts and crooked panels on the prototype aircraft, but where is the photo evidence that the production models have a normal RAM? So far, all photos of "production" models do not differ from the prototype in terms of coating.
Please, find more authoritative sources of information for your videos.

To be honest, USA is so desperate to sell its aircraft. I feel it will get in talks with India with the offer of the F 35 too and try to find a reasonable deal where India gets full and unconditional support unlike Russia, which promises complete technology transfer full support and the permission to modify the aircraft which the Americans would never not even to their closest allies, except Israel and that too only software and internal hardware not the structure itself.
It would be very difficult for the United States to match what Russia is offering currently both are desperate for market of India and India as a desperate customer with fifth generation threats potentially on all of its borders
Bro googled "generic 80s representation of India music"
It was on storyblocks
That was hilarious. approved.
Generic music with generic video shots
Allow me to say my own 57 cents about the nozzles: as always when Russians are involved I would adopt an AND/AND instead an OR/OR one approach.
We know that they were always poised to adopt the Al-51F1 as their own definitive engine so that they didn't just bothered to develop a serrated nozzle for the 30/40 planes they would adopt with the interim one (but they have presented such one for their legacy Al-31F instead), so now that the new one with round exhaust is ready they would complete the actual order with such ones and keep on to developing the squared one.
Once that their own development would be near completion their would evaluate both of them for the Su-57M and successive planes they would adopt, beginning with the ones that will come out from the Su-75 (as this one is not an official VKS designation) private enterprìse program and the two seated Felon they have already announced they would use as a drone air controller.
merry Christmas and great job!
The Su-57 is stunning and futuristic looking! With angular stealthy lines and a cockpit optimized for maximum pilot visibility, it screams dominance and innovation. AND it has AI!
Damn!

Thanks & wishing you a merry Christmas and a Happy New Year! And to you all as well!
1:41 As an Indian, I was like .... "don't say it!...no... DON'T!"
Why?
A MINOR corrections.
The Russians did not say that this flat nozzle is going to be standard on the new engines/planes. They said they needed to develop this just as an option and as well as for international customers of Su-75/57, if they will want it. So the designers did not really change their stance that higher manoeuvrability and resulting thrust is in general better for Russia.
india really wants the 2 seater option. loyal wingman and other drone control is just too much for 1 person in a battle space. if india takes this up, i expect 1st batch of 1 seaters and then a 2nd batch of 2 seaters.
vietnam could be interested but see the su75 as being more a fit for them. argentina would like the su75 but the US is shutting that door with a recent sale of f16s.
argentina cant afford su57. su75 on the other hand maybe. it all depends on new engines and how expensive will be to maintain. su75 could sell very very well as its the only (besides f35) single engine 5th gen fighter. also vietnam will probably want su75 just ability to buy more.
and india who knows. maybe they are giving up on their own aircraft or know it wont fly for the next 20 years so they really want something right now.
@@jebise1126Nop 2028 india jet ready
Vietnam also needs big aircrafts for maritime patrol. Su-27/30 usually fulfills this role. The 90s' Su-27 are reaching end-of-life, they want to replace them with Su-57 or Su-35 and create new units with Su-75.
Malaysia will buy SU 57 soon in 2028 eventually. It's a strong candidate for winning tender in the air force soon.
It's pretty much a trade-off between power(and efficiency) and stealth. It sacrifice a bit of power of the engine for thermal and radar stealthiness. It still has 3D vectoring though so it's still good.
Merry Christmas and a productive 2025, fellas! : - )
We all thank you and Otis for your time to enlighten our knowledge.

How are those many variations of angles and movements being chosen and controlled? By pilot choosing a certain set of nozzle movements or does the computer chose the right package without the pilots input? It seems that specifically Russian jets have a multitude of possibilities.
I doubt the pilot is choosing anything like that, should be computer controlled.
on the su35 the active nozzle is turned on with one toggle switch and has no settings, as Bogdan said
computer chose all outputs since 1980s, its reading inputs from pilot + environment and adjust it to preprogrammed maneuvers, pilot basicaly only have to contol scale of maneuvering
@@olexp9017 Thanks for your reply! Happy Christmas!
@@alexprost7505 Thanks for your input. Happy Christmas!
Excellent video as usual.
I'm thinking maybe they will use both nozzles. The flat ones can be used for Su-57s tasked with penetrating airspace, while the round ones can still be used for those tasked with defensive operations.
Good Video, Gus. Well explained. Wish you a lovely Christmas time at home...😋😋
Great Indian going with superior technology.
You can never have to many videos on the best all around 5th generation fighter in world in my opinion. Thanks for another great video.
The SU-57's nozzles are not completely rectangular and far less restrictive of the thrust coming from the engine. We can also see that the exit part of the nozzle of the AL-51F1 is not flat, like the one on the F-22 nozzle, but it is angled making it closer to a circular shape, which probably results in less thrust loss, since the plume is not going from the circular to totally rectangular shape like in the case of the Raptors nozzle.
Fantastic episode bro! Thank you for all the great explanations! Merry Christmas!
does India also getting it with the stealthier drone S-70 ?
no one never talking about exporting s70
Just in case this is your last video for the year ... we love you Gus.
We revere your content and how warm you are to your fans.
It might be a nozzle for missions that don't require particular maneuverability, thus the aircraft can do whatever it has to do without having to spend so much on maintenance, while the 3d one isn't scrapped but is just used in other cases...
Maybe it is just a feature. You can order the aircraft with either nozzle?
the reality is that outside airshows this kind of maneuverability is not need anywhere. Its cool but ultimately not that useful in a combat scenario .
I don't understand the American air combat doctrine that super maneuverability is not particularly useful in modern air combat... even if they believed that BVR spamming of missiles is the be-all and end-all of air combat now, those missiles still have a limited range and kinetic ability that can be exploited (and defeated) by deft maneuvering?
Just watch that Russian pilot who did that crazy haul-ass flying when he had like 3 or 4 patriots launched against him and hunting him down.
Surely increased maneuvering means increased survivability?
What are we missing here?
@@JayzsMr well the ability to fly with missing or not functioning controls surfaces is surely useful
@@scroopynooperz9051 Super maneuverability is only useful in gun only dogfights tbf, because evading bvr missiles requires speed which supermaneuverability trades for being able to spin around your nose to any position you want. To kinetically defeat missiles you need speed, that's why US weeaboos always talk how useless it is. But it has it's uses outside of battle too, you're less likely to lose your plane to a flat spin or any other difficult situation, so it's quite good in that aspect.
That said, having that advantage is like that anecdote about soldiers that fight with a knife: "to have a knife fight you have to not have your ammo, your rifle, your pistol, your grenades, and then you have to find an enemy soldier that's just like you"
That is the central hub of the turbine. It has no place for afterburner there. And no radar shading or cold air mixing. (maybe mixing is done in the previous turbine stage) In B2 & F117, the engine is buried deep in the body, totally masking the turbine and compressor blades from radar signals. also the long exhaust provides enough time for heat dissipation and cold air mixing. - To some degree F-22 also has that feature. F-35 does not have.
This engine has more power so thrust loss is negligible
This is how the engines were laid out on Rockwell's ATF proposal. Not that mini B-1 looking thing, their actual proposal, it had angled square exhaust nozzles. As I heard it, they did that so they could use a corner of the engine as a narrow corner to match with RCS shaping.
The Su-75 is the platform for Russia's future supersonic robotic AI fighter. on board 5 missiles with a range of up to 100 miles
The mid bay is just large enough for 3 standard length missiles.
Appreciate the new video. Excited to see that IAF may acquire a few squadrons and as usual a panic buy.
Just imagine the buyers remorse all the US allies are having!
Name them
@nickbrough8335 Australia as a start! Israel realises that during the last air campaign they tried to mount with the flying Barn doors, aka F35s, against Iran, they were detected at least 100kms from the border! TBH, even Elon Musk has finally realised that the entire F35 project is a huge scam. Google it! I'm pretty sure all US allies have realised that they've made a huge mistake partnering the USA.
You're joking right?
This has to be a joke. No country that can afford the F35 is going to pick the SU57. Russia can’t even produce them anymore because of sanctions.

I absolutely hate russia - in all aspects; I used to work with russians. Yet I still admire the beauty of this su-57.
I think the flat nozzle provides more benefit than more granular thrust vectoring? What good is maneuvering if you're seen from miles away just cause of heat?
Anyone who says it's a down grade is insane?
But for the Russians to maintain the flat nozzle and be able to articulate the entire nozzle around to b include the extra dimension of geometry is actually genius thinking!
I think that is the most innovative part of all of this, and perhaps that should be emphasized more in the decision? They haven't lost anything by going back to the flat nozzle because they overcome the flat nozzles shortcomings of limited dimensional movement; they also deleted articulation of the side flaps removing a major source of potential fault l failure.....I will presume that the rotational articulation of the nozzle will be designed around a ring gear on a barrel so to speak, meaning that the electronics and mechanical components will be shielded from heat. The US uses linkages on the jet side flaps to remotely articulate those small side flaps, but those linkages are subject to the most intense heat and conducting of heat is unavoidable creating a new source to mask or keep cool. By maintaining the flat 2D control vectoring and substituting by rolling the entire nozzle will provide much more granulator control especially for telemetry and future automated control of systems? For instance individual articulation between the 2 jets could assist in tighter rolls or maneuvers especially if machine learning from pilot data? There could be instances where AI can optimise the thrust vectoring to assist the pilot?
I'm waiting to see if we get more monowing vector shapes in next generation air craft that integrate the jet engines more inboard so that the heat signature is more masked by control surfaces such as vertical stabilisers or V tail designs and using more aerospace ceramics to mitigate radiant heat propogation?
To put simply that with speed and pulsejet propulsion on the horizon that the typical jet and high-speed maneuverability becomes a low priority over top speed performance. At least the with the flat nozzle design factor allows for "potential" future proofing the air frame, however I think the Russians are more likely to do a complete design shift when they declare their air craft of designated generation? The Russians will like to make a clear distinction between what they consider 4th 5th or 6th generation where America has become wishy washy especially with the blending of 4th to 5th, but i think the confusion is a strategic thing also but who really knows?
I'm not pro anything but I'll acknowledge if I think something is a wise decision or not?
In my opinion this shift is a wise decision but I'm no military expert, it just makes sense to me scientifically? It's physics. There are also marked times in history where the logic in design makes sense to the physics equations but in reality we discover otherwise or we discover new phenomena at play that wasnt accounted for whilst modelling etc? All kinds of things can go against logic. But scientific process is not about success of 6 failure it's about testing the hypothesis and it's those things that fill in the counter intuitive hypothetical blanks that creates innovation. Logic now says that you shouldn't go so far down a design path that traps you when something revolutionary happens in engineering....... You keep your opinion open for as long as possible.
Plasma is the next state of matter that humanity will harness for transmutation of materials and that's when we will see a completely new science arrive. I can't wait for that to occur!

Jokes aside, I like the Su-57 over the F-22. Hope it gets the good avionics aka stealth feats in the future.
Flat nozzles looks dope!
Flat nozzles that can rotate in 180 degree arcs before pitching seem like the ideal.
Engineering that would be the clever part.
(Just interacting to help the channel, here.)
I think it's to make it more attractive to the export market. One of the criticisms of the Su-57 engine nozzles are not stealthy
One obvious advantage Russia has is their availability to titanium which is a very important component in high temperature engine components. The new redesign of the SU-57 engine nozzle (to increase steal profile) a logical move. India's renewed interest in the (now combat proven..) SU-57 is also quite understandable.
You keep asking yourself why they do this ?! Here are a few simple answers : The Americans constantly comparing the 2D exhaust of the F-22 Raptor with 3D exhaust an they said that the 3D vectored exhausts like the ones they tried on the F-16 VISTA have a smaller angle of deflection of, say, 23 degrees, while the 2D exhaust has up to 28 degrees; The Americans also argued that the Russian 3D exhausts have too large an infrared reflection and can be easily tracked by advanced IC cameras; this new form of 3D exhaust should have a stealth shape with a reduced infrared trace that interferes with IC camera tracking; ionization of the exhaust with negative ions can allegedly further reduce IC reflection because negative ions in the air increase the absorption of O2 molecules into the cells of living beings, dissolved O2 is precisely reduced when heating water and air, which leads to the creation of positive ions that are fought against by negative ions; so the negative ions somehow restore the normal properties of the unheated molecules of the atmosphere even though they are heated and bring them to a state before that, which can reduce the IC reflection; this form of 3D exhaust is what I would call an aerodynamically unstable "3D" vectored exhaust which can further increase maneuverability in air combat and attempts to avoid missiles fired at this aircraft. I thought about such exhausts and very similar ones more than 10 years ago and now I have consolations that are decades ahead of this solution. In any case, the Russians are showing the Americans that they can correct what the Americans rightly criticized.
I think it's unnecessary if it tries to reduce radar section from the back if the thrust loss is anything above 10%. Does the AL 51 have more thrust with the loss of square nozzles against an AL 41 with round nozzles? If yes then it might be ok, but only if the Su 57 is capable of supercruise with these nozzles. the Su 57 already showed its stealth capability when it was flying above the frontline at 5000+ meters of altitude when it shot down the S-70 drone after it lost control over it. Any other jet would have been shot down by patriots before it could even get to the front line at such altitude.
The fact that the Russian Ministry of Defense does not want more Su-57s with AL-41s does not mean that they will stop producing them right away. Contracted aircraft with old engines will be produced for another two to three years.
They did this for airshows, like many Flanker variants.
To be fair, the al-41f1s (su-35) never had an a 3d thrust vectoring nozzle. The 3d effect was achieved by tilting the engines along the axis and a certain distance between them, which made it possible to transmit the yaw moment of force. On most of the Su-30 this is also implemented, with the exception of those vehicles that came with Salyut engines that deflect the flow of the supersonic part of the jet stream. On the al-41f1 (su-57) everything is most likely done the same.
Apparently, this solution is optimal for twin-engine machines in terms of simplicity, weight, reliability and ease of maintenance. With this flat nozzle, judging by the same inclination, the story will be the same. So in this situation, the choice between a flat and a round nozzle will be a choice between a little more stealth and a little less thrust, and vice versa.
Glad to see you my friend, you’re looking well
All the best to everyone
I just wondered why they were canted like that by 45 degrees. are they correct? do they rotate too?
IAF will soon enough will look like museum. With all these varients of different aircrafts.
The angled position of the nozzles (2.5D) on the SU 30 MKI is not limited to India as a customer, but a common part of that SU30 MK version used by many other customers, including the Russian airforce in their Su 30SM. Since that Su 30 version is produced in larger numbers than the Su35, that type of nozzle is actually more common than the 3D TVN in the limited number of SU35s that are available.
Wrt the loss of manouverability, one has to keep in mind, that unlike the Su35 or the F22, the Su57 has additional LEVCONS and is not limited to the TVNs alone to improve it's turning ability. Going for the more common Su 30MK system, but in an improved version that also seems to be way more beneficial in terms of IR reduction and propably costs, without losing too much in terms of manouverability seems the sensible solution. But then the question must be, why only now and not 10 years ago?
The reason is , india pulled out of joint development project and russia doesn't have money to develop.. all these changes to to impress indian to invest in the program. Indian airforce had identified 52 shortcomings., one of those were round nozzles.
@nighthawk4028 Common misconception especially in the west, the reality was very different. India simply didn't had the money to go for the special version they wanted intially, so they continuesly cut down on their own requirements and numbers within that joint programme, to the point that under the new govt not even sufficient numbers of legacy fighters were procured, let alone NG fighters. The govt hides that lack of funding today, with the claim to support Indian projects, because that delays any costly procument for years. IAF is not allowed to buy even the first Su57 in any useful numbers, simply because it's costly to procure and operate, while there is no funding available.
A thought crossed my mind. They are working on the PD-35 engine with composite fans. What if the 3 LP fans of the AL-51F1 is composite as well? That would potentially reduce RCS.
Thanks for the 2D Vs 3D thrust vectoring, Looking for it for many days but didn't find any video useful.❤
Welcome back Mr. Millennium 7*!
Not having anything from you from days was excruciating!
Above all THOSE DAYS...
It makes sense to me... The SU-57 needs better nozzles if it wants "stealth".
Thrust and maneuverability are 4th gen focuses that aren't used often when "stealth" is necessary.
Considering how much easier the serrated Low Observable Asymmetric Nozzle (LOAN) of the F-35 are to make and how effective they are I am also rather confused why they would opt to go with the Flat Nozzles.
Still they look very cool on the Felon. A most informative video as always.
This is probably the engine that will be used on the Okhotnik and they are testing it on the Su-57
It`s can be a just flying stand. Remember, the same engine can use LFI Su-75 "Checkmate" and UAV S-70 'Okhotnik'.
These aircraft share a single modular platform. This allows for faster production and easier service. The Russian aircraft are also characterised by an open weapons architecture. Each customer can build its own aircraft, for its own armament, without any prohibitions. Thus, the customer will protect himself in the future. It has long been known that the USA imposes sanctions on its partners and thus the purchased planes are transformed into ground museums, new parts cannot be obtained for them and weapons cannot be used.
Su-57. We need more Su-57! He's awesome!
Most of the time I haven't really got a scooby what the hell you're talking about but I still always click & enjoy the videos. Ever thought of a side hustle - a 2nd channel "The adventures of Otis"? 😅😅
Русскую технологию"стеллс" можно прикрепить на любой самолёт, а в остальномСу-57 -лучший в мире!
