This *Huge ENGINE* Will Change The Aviation Industry FOREVER!
HTML-код
- Опубликовано: 9 май 2024
- What is the World’s largest jet Engine? If you said the General Electric GE9X then you'd be wrong, but it’s close. The world’s largest jet engine is actually the supersized Rolls-Royce Ultra-fan.
Although the engine may still be in its demonstrator phase, Rolls-Royce has already tested it at maximum power. And looking at what this massive engine could offer to aircrafts, it’s safe to say that we might well be looking at the future of aviation.
So just how big is the Ultra fan engine? How does it operate? How does it compare to other large and powerful engines? And finally, what are its prospects in the aviation industry?

It's Aircraft not aircrafts. whoever made this video sucks !!
Have just done the same.
They also pronounced “triple” TRY-PULL.
Here here.
Anally retentive 😂
It’s a computer generated voice IMO
RR, the epitome of UK engineering.
Yup. The rest of the western world is ahead.
Playing catch up to the US as always. XD
@@ImpendingJoker... boo hoo. Cry yourself to sleep.
@@ImpendingJoker
Yes, just like they did when the RR Merlin was built under licence for Mustangs to protect those brave US bomber boys over Germany in WW2. GE's first turbo jet engine was British and built under licence BTW. Every day is a history day...😀😀...
lol you got owned@@ImpendingJoker
Every time I hear “aircrafts” I switch off. Aircraft is the plural of aircraft.
You are clearly upset easily then ❄️❄️
@@justinmcdaid2594 saying "Aircrafts" is ignorant... especially when this is not only the topic of the Video - but of the whole CHANNEL.
Yep, it triggers me too, smacks of illiteracy
yes, and they cost even more moneys
damn u now i cannot unhear it
Very informative for the layman, being British I am very proud of RollsRoyce.
Lousy computer speech reading. When do you pronounce the word “triple” as “try-ple”.
😂👍🏿...I heard it too🤦🏿♂️
Gotta admit it’s pretty darn good overall. It’s come a long way.
@@suspicionofdeceit
No, it's not.
It’s an AI vid. To be expected
Also, the way it pronounces PRAATT and whitney. Still, it's pretty good, sounds very natural otherwise.
Lol the narrator is an AI bot 😂😂 "Pratt... Pause Whitney" 😂😂😂 this channel is a hoax
PRATT……..
WHITNEY
Too many of such channels popping up these days
HOUSTON… We have a problem
I really fear that this is just the beginning. What if 5+ years from now this is the new normal? AI voices are _nearly_ indistinguishable from human now, all thats needed to catch up is AI faces (aka Max Headroom). Once those are believable, we'll have new "hosts" that don't even exist, just testing new AI algorithms to grab our attention and maximize engagement. An unknown number of YT comments are fake thanks to LLM. Fake Plastic Trees man...smh.
Tufan , that RR ceo has an appropriate name .
This engine is clearly the Rolls Royce of turbofan engines. Pun intended!
You mean it's based on an old BMW 7 series?
"Aircrafts" is among many factual errors. Stock footage and a desktop editor are no replacements for expertise. SMH
Thanks for your insight and knowledge
Surprisingly, quiet are these large turbo duct fan engines.
An early day turbo fan of this much power if it had ever been built would have broken your ear drums upon take off along the runway
"Used cooking oil" This Net Zero insanity is becoming more dystopic, if that`s possible!
Awesome Video 😊
A350Neo would be nice!
Correct me if I’m wrong but you stated that the combustion temperatures were reduced by running a leaner combustion ratio - not in my book. This apparently reduces Nox emissions but I thought it went in the opposite direction. Normally, increases of combustion temperature makes engines more efficient but increases the Nox.
Efficiency is limited by the max allowable inlet temperature of the turbine. The flame temperature is significantly higher and lowering this does not necessarily bring down the efficiency but reduces NOx emissions effectively.
The combustor cans and blades are protected with cooling air shields resulting in lowering the hot gas temperature after the combustion at the turbine inlet.
So, a turbojet core driving large fan blades. Seems to be approaching the original turboprop engine concept.
Bring it on .... Baby!
The ge9x has already been tested. So I don’t know where the part on the “ge9x not being tested” came from.
Great Video.
It won't be long until someone makes an engine that makes 150,000 LBS of thrust
It will. There's no need for it. The market has moved away from the hub and spoke model, thus super jumbo's are a thing of the past. Fuel savings goes way ahead of extreme power. The Ultrafan is an example of exactly this.
You need a Aircraft manufacturer to build a aircraft to use that power and multiple airlines to buy it. Thats the problem for engine manufacturers, the have to be clairvoyant!
I can't see any future aircraft, needing 150k LBS thrust per engine. Unless the A380 was re-configured to a twin engine aircraft where two 150k LBS thrust "might" be needed....... but thats never gonna happen.
I won’t fly on an airplane that doesn’t have that JP-4 kerosine smell.
I just visited the US Air Force Museum in Ohio. The jet engines on large transport aircraft during 1970 to 2020 seem tiny by comparison to today’s new engines. My question is: How much heavier are the high bypass engines?
Literally a friend of Aviation Future
CFM and GE have the most efficient turbine prop
It's very reasuring to know that so many aircraft engine manufacturers are competing to produce eco-friendly engines. With global warming increasing constantly, this revolution will be vital for human survival in years to come.
Maaate, it's an aircraft and many aircraft. Aircrafts is not a word. Doh!
i want to see it on an a380
4 of them. And 6 on the AN 224
you never know when this can hold enough power for 6 engines when there are 4 of them🫠
@@hardbugemon1017 Sensation, "A380 went supersonic, created a sonic boom which flattened half of New York" :-)
@@hardbugemon1017 you don't need 6 engines
@@stefanweilhartner4415 yea thats what im trying to say (:
literally just gone back to turboprops. Turbojets have RPM limitations since once blade tips start hitting supersonic, bad things happen. So, we're left with just making the prop bigger and bigger
Let's get a few things straight. These are turbofans, not turbojets. A turbojet is a jet engine with no bypass.
Secondly, many turbofan engines have fans where the tip speed goes far above the speed of sound. Take the GE90 115B for example. At full take-off thrust for heavy loads, the blade tips hit about Mach 1.66 depending on climate conditions.
The idea that turbofans have the same kind of issues with going supersonic as a turboprop, is way, way wrong.
The industry is interested in slow moving fans with a lot of pitch because it moves more air slower, thus creating less noise. As for the PW RISE engine, we'll see.
The next step is to include an Induction Motor in the rotor fan system that can power the fan silently with electric only, along with the development of a start-stop system in the bypass engine that can fire up instantly. That would create a kind of hybrid Prius version of a jet engine and reduce fuel use further, as well as resulting in silent landings.
Yes, make it adaptable to be a hybrid. Battery technology is improving greatly. Safe solid state is going along nicely. By the time an electric motor is incorporated into the unit battery technology will have advanced.
@@johnburns4017 You guys have each got yourselves a job! Turn up on RRA Derby doorstep first thing Monday morning!
Seriously, it's a bit of nostalgia for me when I watch this, being a retired engineer who worked for a sub-contractor to RRA, but on the UK nuclear sub fleet.
Batteries are way too heavy for putting in aircraft, their energy density compared to fossil fuels sucks.....
@@chrissmith2114
At the moment batteries are heavy. They are advancing at a phenomenal rate. Even right now they are suitable for landing an aircraft over built up areas. There are few battery planes around.
@@johnburns4017 If you want a plane that can carry a battery and little else, build a battery plane.. If you want a plane that can carry passengers and freight - build a plane powered by kerosene...
A target introduction into the market in 2030!!! That's just in time for the huge backlog of airliner orders to be pushed out and over with.
When they rebuild the An-225, six of these would be a good idea.
Hrrrm,.. Lean running engines generally run hotter, not colder.
Covid didn't affect Roll's big engine, the bearing failures leading to A380's having holes through the wings when the fans around the bearings let go, that affected the bottom line.
RR. Buy four, keep two in the air.
It's "aircraft", not "aircrafts". 'Aircraft' is both singular and plural.
I think that may be a Britishism.
@@markkinsler4333
Nah. It's AI.
6" size difference gives rise to an increase in thrust...and an increase in performance.
Not when the fan is geared it does not. Geared fans achieve efficiency by having larger fans running slower and lose out on thrust.
This really feels like advertising... not a critical engineering discussion
Clean fuel can be made from the fisher tropic process Using Cole
Oh dear. Clean coal has been a fraught subject here in Appalachian coal country. I'd thought they'd given up.
What aircraft will this engine go on?
More dire tripe, where are the antigravitic engines being used on the TR3bs??????
Airbus is leaning toward GE Snecma unducted fan for the narrow body replacement. It’s very telling if Boeing swings toward a superfan for the competition. It will be an all in bet and Boeing has not been making great decisions for a while.
So, let me get this correct. We move the seats even closer together, charge more, and then put bigger engines on it to handle the weight of the extra passengers. OK, I thought that's what you said. Next, remove all the seats and have shoulder harnesses holding everybody in.
Have you seen that Finnair has begun weighing passengers? You think boarding is bad now, wait until large families have to weigh each child. Does a passenger weighing 200 pounds count as two passengers.
@@mosulman7773 it's voluntary
@@mosulman7773 Weighing passengers is nothing new. Way back they used to weigh the passengers and their luggage all the time. Some plus-sized passengers insist on getting two seats for the price of one. Does a skinny passenger pay less for using only half a seat? People in general are getting heftier and this affects the aircraft's weight and balance. Think of it as a safety feature. FWIW, I am retired USAF and did flight training so I know a little about this. They also know how much fuel is on board by its weight, not by quantity. Hope this helps.
So, the GE9X is the world's largest production engine.
0:53 aircraft not aircrafts an aeroplane is aircraft, lots of aeroplanes is still aircraft. Aircrafts, that word does not exist.
"Aircraft", like "sheep", forms its own plural.
The most powerful engine today is the General Electric GE-90. It generated and sustained 125,000 lb of thrust on a test stand; as deployed on a 777-200 or -300, it generates 110,000 lb of thrust. Unless the Ultrafan is rated to produce more than 110,000 lb of thrust, it is NOT the most powerful (although the fan diameter might be larger). The Ultrafan is Rolls Royce's version of a Geared Turbofan. This engine is very late in coming, which is why it was not available to the Airbus A340 when that airplace came out. Instead, the A340-300 was left underpowered, using CFM-56 engines instead.
The 777-200 does not run the 115B.
@@AB-80X So only the -300?
@@ronaryel6445
Yep
Thumbnail says "huge engine", not biggest. And the very idea that the UltraFan should have been developed in 1987 along with the A340, is ridiculous. Its not late in coming, it more advanced than what its competitors can claim for R&D. Ever since the success of the A350 with its RR engines, there's a campaign led by some against RR, based on 'hard cheese'. Get over it bud, just because American airlines except Delta are investing in GE for w/ bodies, doesn't mean the rest of the world needs to. The A350 will continue with exclusively RR engines until at least 2030, and then hopefully extended. GE might like to buy their way on to the programme then, assuming the B777X is not certificated by that date still😀, but Airbus will probably be producing a NEO option then anyway........
@@artrandy Read my comment more carefully. Rolls Royce is late on the Ultrafan in relation to Pratt and Whitney's GTF. It wasn't the Ultrafan back in 1987; it was an earlier version of GTF technology, and that engine fell badly behind schedule and ultimately failed. And Airbus was expecting it for the A340. The Ultrafan is Rolls Royce second attempt at making a GTF.
All part of the plan to make air travel unaffordable for ordinary people.
stupid comment from a stupid ordinary person.
quite the opposite if you look at the aviation industry over the last 40-50 years. Flying has never been cheaper. You can book a one way flight with Ryanair, Wizzair, Easyjet etc from £15...... basically the price of a UK packet of cigarette. I doubt that was the case 30/40/50 years ago. Ordinary people have never had it so good, choice and price of food from all over the world, choice and range of cars, aviation, booking an Hotel, Airbnb, hostel online cheap AF, cost of high speed internet, cost of satellite (starlink), cost of clothes, cost & availability of everything has got better due to technology, economies of scale and globalisation, the "ordinary" people are doing just fine today compared to the 1940s 50s 60s 70s lol
Even the tile tells you it's BS. We all agree.
"Inches", "Feet"? In the 21st century?
Typical Americans, they like to be confusing and different from the rest of the world. Just like the sports they play. American football, Baseball, Basketball........ 3 sports NOBODY else in the world plays hahahaha

Talks about RR all the while showing GE or CFM engines.
The RR engine is only in testing. Probably no pictures available of the actual engine.

That's an assumption, not a fact.
@AB-80X It's no assumption. The RR gearbox was tested handling the output equivalent to 400 Formula 1 cars continuously through the gears for what would be the equivalent of a D-check. It was fine. Not ONE P&W GTF has achieved that. RR were not rushing any gearbox to market after the Trent 1000 debacle.
@@nathd1748
The fact that you use that kind of silly comparison, tells me a lot.
Who is serious and uses such a comparison. What torque, at what RPM, at what temps, for how long etc.
What you are completely missing is the fact that nothing is proven until it sees an actual work environment. There has been a lot of engines and components tested for various things over the years, which during tests looked remarkable. Then when put into service, they did not work.
When someone tells you something along the lines of "The torque of 400 F1 cars", they are doing nothing more than trying to present impressive comparisons to lay people. The P&W GTF is in service, and a much smaller engine. The Ultrafan is not, and obviously a bigger engine has a bigger gearbox. Not a big surprise I'm sure we can agree.
@AB-80X Since you don't know, the Ultrafan gearbox is designed to be scaled down to 25,000lb just bu reducing fan and compressor blade architecture.
Had to give up - spoilt by intrusive background noise. Great shame.
If it hasn’t flown yet on a jet then it’s not the largest.
Is this a robot voice? Why does he/it say 'aircraftS'? and "emissions would more than trYple".
Maybe the engine would bring standard jets MACH 1.0.
Present engines could do it with some modification. It's the airframe that needs to be altered and reinforced. But we earthlings would have to deal with the sonic boom.
If you take an A320, 737 or 787 etc. to Mach 1, the plane will tear itself apart.
Just ask Lauda Air.
@@markkinsler4333 Reinforcement? Not even remotely enough.

Yet carbon dioxide is only 0.04% in the atmosphere and mankind's contribution combined is only 3$. So, if carbon dioxide drops below 0.02%, everything dies. While making things more environmentally friendly is what we should strive for, the "global warming" due to carbon emissions sounds far fetched and just may be a way for billionaires to make more billions from government subsidies. Otherwise, all scientists would agree that mankind is responsible but there is not 100% consensus.
No it’s really not, if you understand thermodynamics you will know that heat retention du to CO2 is a real thing. And tbh all real scientists do agree that global warming is a thing
The semi-literate "aircrafts (sic)" man or program needs booting out of the narration job.
Likewise the script writer needs another job where he/she will learn that AGW has nothing to do with CO2. The scam has very little time left.

Why is there competition between the voice and stupid music tracks?
and the equally daft "woosh" noise when changing scenes....
The current largest PRODUCTION jet engine is the GE9x.
The Ultrafan isn't in production yet.
That PROBABLY will change in 5-10 years - if it finds an aircraft to mount it on.
RR almost went bust years ago over a new engine development and the government had to bail them out, they need to be careful this does no happen again
No chance of happening. The new design is already developed and paid for

You lost me at "tripe-all". Come back when you can listen through your text to speech and edit errors.
That was more irritating than informative.
Is this an ad for Rolls Royce, hate to tell you Pratt already has a Geared Turbo Fan and GE already has a Composite Fan Blades.
Hate to tell you that RR was originally a 50% shareholder in the PW Geared Turbofan programme but decided the gearbox was a pile of shite and withdrew. How correct they were??!! 400 aircraft grounded with P&W lump of shit GTF.
This sounds a lot like an Republican American, in complete denial of climate change!
Fuel efficiency is all about revenue for the shareholdets, and renewable oíl does not help in any way because, unlike food and water, the oíl reserves are not a problem.
'Sustainable fuel' = chopping down rainforest to grow crops that instead of being fed to humans, get fed to aircraft engines = madness.....
An engine looking for a plane ! RR needs a single isle engine bad management

Geared engine will be its downfall. GE is still the best powerplant
What when the gearbox has been tested for 6 years continuously? And the UF is knocking out 110k thrust at double digit fiel savings over the GE9x?
There is no plane in the pipeline for this engine.
Because UltraFan can be applied to RR`s range of engines it`s thought that A350, B787 could benefit in the future. The demostrator engine is at the very top-end of size & power, there`s speculation that if RR decide to design a narrow-body engine then UltraFan could be incorporated. My opinion is they`ll put the first one on the A350-1000, this will increase it`s range & may lead to a stretched version. It would be sensible to offer something for the Dreamliner too as both these aircraft will be around for many years.
Oh there IS. RR have a scaled variant under build to offer Airbus a 3rd option for the A320 series. Plenty of sales in the programme to grab a slice.
@nathd1748 yes the new tech but not the engine they are building and testing now.
@@geoeneas they are almost finished building a scaled version of this UF. You'll hear about it in about 2 months.
@@nathd1748 I'm wondering (no sarcasm) how this scaling down will turn out. The high bypass ratio of the demonstrator is due to huge fan and very compact core. Can they compact the core even more to get the same bypass ratio with smaller (way smaller) fan that may be feasible for a narrowbody aircraft?
