DST- Engines What type of coupling did you use? It seem like the turbofan is not directly on the shaft.
Great work man. It looks beautiful! 😁👌
The fan is directly driven :)
I've wondered why most RC Jet motors don't have air bypass or if they do, they're not fan driven (Iike it was just chance in the mounting). Nice job. In full size, I think as much as 60% of thrust is bypass.
@@DSTEngines Why do we hear the turbine spin up on startup while the fan is stationary? The compressor must be linked to the turbine, right? I think this must be dry humor :)
I also noticed you had the engine mounted on spring loaded rails. Can you reveal static thrust measurements?
@@frankhage1734 big airliner engines: the fan spools up later top. Because the core engine must build up enough gas pressure to the low pressure turbine. Thats normal.
Amazing, the world's first jet powered kitchen door.
:)))))
LOL!!!!!!!
😹😹😹
🤣😆😄
I think it’s the fascia for a dishwasher door. This is my contribution to the Internet for 2022.
Did anyone notice that it produces enough thrust to make the vegetation move, which are on the other side of the pond? Amazing.
I wonder how much thrust that is?
LusoiHardware yeah I see that too.... that is a lot of thrust!!!
Yes, it was really moving some air.
It really sucks down the fuel as Well.
I was thinking the same thing! That’s pretty bad ass.
Absolutely insane that the trees all the way in the back were swaying from such a little engine.
I absolutely love turbine starting noise, i like every "stage" of acceleration.
This thing is so little, but produces so much power and is so loud lol.
Who else was watching the fuel go down in the bottle?
KROOK3R yap i noticed and the thrust on the other side Of The pond as well.
All the time mate
#metoo lmao =)))
Yup, that thing just drinks doesn't it.
Yeah, all I seen dollar signs disappear.
I am impressed. This is actually an engine, making significant useful thrust.
Thank you for your comment. :) im glad to see you here.
If agentjayz is impressed who am i not to be.
I agree, I bet this could power a full size glider or Sonex
Correction first high by pass ratio engine on RUclips
@AgentJayZ Collab?
Very impressive. I think it's also incredibly fuel efficient for the amount of thrust it produces. Just look at those tree branches fly around!
I tell you!
A specific fuel consumption of ~1.25 (kg/h)/daN , it's only 3 times more than the best turbofan existing.
Really great job!
A turbofan on sealevel VS midair
Considering modern turbofans have much higher bypass ratios, FADEC fuel controls, controlled turbine casing clearances, and modern annular combustion chambers, this is fairly efficient
@@Taydrum I mean... even if you built it to the exact same standards as a commercial aircraft powerplant, it would never be anywhere near as efficient and that's purely down to compressor and turbine tip-to-case clearances. They _need_ to be a certain size, no matter how big the engine is.
That said, engines used in airliners kinda cheat, at least with their turbine casings, where instead of super precise manufacturing, they use abradable seals cut into by the tips of the turbine blades (usually with an abrasive coating of their own). That's as tight as it could ever possibly get.
@@Taydrum It's still less efficient than a Kolibri T-32 microengine.
How not to love this engine? It looks and sounds EXACTLY like a full sized high bypass turbofan!
Truly amazing
@Abr 123 lol
The amount of thrust that creates is amazing, and it's pretty cool that we can visibly watch it consume the fuel.
Did anybody noticed the way fuel level dropped ? And the vegetation behind moving due to thrust 🔥🔥😮
only the vegitation
Yeah
Sure did. If you watch the fuel for a while, you will see it dropping when the engine is on full thrust. Very nice engine though!
Damn....this thing is poetry in motion. LOVING the twin spool design, imagine it with a variable stator stage!!!
Now all you need is to mount a few to a broom and you can fly around town like a witch!!! Best Halloween costume EVER!!
The trees blowing in the background shows how much air this thing moves!! Awesome!!
dang i thought you were joking but you arent
Your neigbours are really happy you got a jet engine in your garden
HA!! 🤣
hahahahaha
Now if he put an electric generator along the axle, his neighbours could probably really happy to have him during the blackout.
I would
I'd be popping my head over the fence asking how much thrust it puts out 😋
It's amazing to see the rig inching forward every time the engine spools up! Not to mention the fuel vanishing from the bottle, and the trees moving in the back.
I have been getting quite a few questions on one of my turbine videos about the feasibility of the turbofan. Very nice to see one build, well done!
Who else was watching that behind distanced plants and grasses were shivering ??
Amazing thrust prower
I saw it 😊😊😊 powerful thrust.
If it powerfull, why the desk doesnt move
@@djimanufacture7682 for the same reason that the plane can full throtle the engine just holding weel brakes lol
Wow that's true
Lolz .. the jet engine is also bigger in size than it looks
Hopefully I’m not the only weirdo who loves the sound of a Jet’s engine. 🤪🤪
I love the noise of the Jet and piston aircraft engine ✌👌👍
And the smell...
I love the sound of a jet engine it just makes my blood pressure high
No your not alone
I love talk over the noise of jet engines, and being able to hear myself.... yeah I'm tat guy! ;D
If you had one of these next door, I would consider you my best friend:
ruclips.net/video/uFquXyoeojQ/видео.html
Very well done, and designed! Not your typical rc turbine model, with only a centrifugal compressor and single stage turbine! Excellent!💯👍
It *is* that though - but dressed up to look & act like the real thing. This isn’t some multi-compressor set-up - it’s a normal single-stage engine in there. But the moving front blades is a fantastic touch - but they can’t be directly connected - even Rolls Royce would struggle to come up with a blade ‘that big’ & spin at 140,000 RPM. In real plane engines, I think they only get to about 12,000 RPM - surprisingly ‘slow’. There will be some blow-by for sure - but the majority of that thrust that you can literally see, is from the engine nozzle.
That's absolutely brilliant and sounds let alone looking like it performs extremely well especially how clean the combustion is and the amount of thrust it appears to be making is incredible stuff! 👏 🤯 that make one bad ass RC jet liner!
This is awesome. I've seen a lot of home made turbojets but never a turbofan, especially not one this amazing. The way it's blowing those trees is just ridiculous.
Bloddy hell ! I never noticed that!
I know , very clever, really fantastic kit 👌👌👍👍
As a 19 year kid that’s studying aircraft engineering, this is amazing! First of its kind that’s not electric. Good job you guys!
Thank you :)
@@DSTEngines Speaking of non-electric, can your jet engine run on E-85 or 100% biodiesel? Can you do a thrust test of that? I love alternative fuels, as long as they are ethically grown. :)
@@thatguyalex2835 if its possible to get E-fuels, I will use them every time for test runs.
@@DSTEngines Awesome. That would be amazing. :) E-fuels are even better. Porche is working on some E-fuels (for cars) as well as an aviation fuel company (for planes)
That looks powerful dayum
Look at the bushes behind, and the fuel decreasing whoa
What a awesome work man! The sound is incredible! Great to see the thrust on the backyard. Seeing your project comes in mind the GENx engines. Congratulations
Loved watching the fuel level drop! Awesome piece of machinery!
It's amazing to see the rig inching forward every time the engine spools up! Not to mention the fuel vanishing from the bottle, and the trees moving in the back.
Amazing engine!
The trees in the background moving that thing is powerful
This is incredible! Outstanding work!
you ever see something crazy enough to just make you laugh out loud? seeing that fuel disappear did it for me
Didn't expect to see you here
you
Some people like JAZZ MUSIC... classical music... rock music..... I LIKE TURBOFAN!
You've forgot to mention EDM and Turbofan... that's a whole new category. xD xD
Now to build a scale model of a GE 90 and really piss off the neibours.
I like turbofan, turbojet, rocket, AND jazz :)
Impressive. With two of those engines, your Maximum takeoff weight for the aircraft could be 85Kg and be a comparable power to weight ratio of a Boeing 747-300.
Funnily, the engines remind me that of the classic 747s.
@@bmc9504 weren't those a lot skinnier?
747 used the first high bypass turbofans…they looked fairly similar, at least proportionately.
@@SolidBlueBlocks early ones were thick at the front and thin at back. Now they're just huge.
Very impressive! Loved the way it guzzled the bottle of fuel.
Imagine! You just bought the house next to this guy, and didn't know your neighbor had a hobbie!
i'd get into his hobby!
If you build working model turbofans.....you dont need neighbors any more.....
He'd be the best neighbor ever!!!!
I'd be over all the time asking him dumb questions and trying to help 😂
If only my neighbor was like this.
I never get the cool ones lol.
As a former Army helicopter turbine engine repairman, I will say... I am impressed.
Turbine engines are mostly all the same. But much more complicated than a jet engine. Turbine engines have one shaft for the compressor turbine and one for the power turbine. Two completely separate yet related necessities.
Jet engines are so much simpler, they don't deal in torque... just temperature and thrust.
Turbine engines are where the efficiency is though, they waste much less of the heat energy.
I assume you mean turbofan engines rather than turbine engines as all jet engines; turbojet, turboshaft(your helicopter), and turboprops are turbine engines as they harness the enegry of expanding gases via one or more turbines. As you stated the complicated portion of this engine is the dual concentric shafts running from a high and subsequent low pressure turbine to the compressor and finally the fan. What an awesome little machine!
A jet engine IS a turbine engine. I jet engine needs a turbine to drive the compressor. The turbofan, of which this is obviously has two shafts with a power turbine to turn the fan.
the tree in the back moving with the thrust. Incredible!
I love watching the trees move in the background. You could move some air with this thing.
Wow..... the amount of air / thrust that turbine engine generates is incredibly.
Incredible! you managed to make a realistic twin spool high bypass turbofan engine! that's an insane level of precision required !
Gorgeous! Now hang that baby under a RC Dreamliner!
That would be magnifique!
I was thinking the same thing! The chevrons look great
Palmeiras na tem mundial
It's powerful ! You can see the trees in the far behind is swaying like hell while this thing is at full throttle. And the fuel tank is like leaking.
I love that growling noise from 2:15 - 2:34. That noise comes from the tips of the fan blades going supersonic, which is just incredible.
I didn't hear any buzz
The growl is somewhat similar to actual sized engine as well,which tell us that this engine will kick asses
Sorry for the necro. I didn't hear a growling noise. If i missed it, it's not the fan tips going supersonic. 200mm fan at 15,000 RPM is nowhere close to supersonic.
mustang50driver around 314 m/ s is still wicked
@@abnayr8440 except your math is wrong. It's half that at 157 m/s tip speed
Ok I need 4 of these and a personal ridged wing suit
Jetman Yves Rossy was looking at using two turbofans because near the same thrust as four turbo Jets but with better fuel economy which equals longer flight times.
And a brain!
Uriah Siner probably only 2 to sustain level flight. But hovering... :)
A swing suit like Falcon
Search gravity industries and have a look at what they are doing with some minijets
Awesome!!! you can actually see the gas level dropping rapidly as you throttle up and the trees behind are in a CAT 5 tornado! Nice work!
Thank you😊
That's Amazing! I like how the fuel decreased so fast...
wicked! i had a similar albeit much smaller testbench setup a few years back :) great job and very nice and clean setup you got
You walk behind the exhaust to film us the best view. Thanks so much.
Já vir esse vídeo várias vezes e todas as vezes eu vejo até o final como se fosse a primeira, achei muito legal esse motorzinho ...
My god that engine drinks like a fish. The fuel tank gets emptied quick. What a fantastic engine you have made there! Many congrats.
Imagine this, you’re testing an engine with your group and you hear someone say “BIRDS!”
Starting the APU
Amazing power. Love the fuel consumption in the bottle hshs
Absolutely amazing. Great job!
Okay, that was ridiculously impressive
I absolutely love this thing! Here, take my subscription
Wow! Quite impressive. As a pilot, I know the tolerances on these things are extra slim
First time to see a turbofan engine model, great!!
The jet blast of this thing blown my mind!
That's really cool! Wish my neighbours had a jet engine, I'd be right over for a beer! 😂😂😂
So cool, its the coolest mini jet engine that i've ever seen 😍
Thank you :)
DST- Engines so... how much for 4 of them? I’d love to build a super light jet to fly around in. Imagine laying prone inside a mini F111....
Wicked cool! Shocked at the rate of fuel consumption. Dude the neighbors must love you!
The fuel consumption is amazing!
This prototype consumes more fuel than a 5.7L V8 350 engine - still fun to watch how fast the fuel disappear :)
well did you see the power lol probably push my car...
Too close to call
"5.7 liter V8 350"... you must have worked for the Department of Redundancy Department?
Push that 5.7L to the limit non stop and see how much it consumes...
That jet engine will propel the car to higher speeds than that V8
Looks like a mini GE90 or GEnx engine... Amazing!
The engine is fantastic, but the garden is absolutely gorgeous
Laf, thought the same thing. Nice landscaping, pond…dog paradise.
Impressive. Nice linear bearing test setup.
Another member of the clever buggers club that's awesome
Right now is the best time to be an RC enthusiast! So much is changing for us its awesome!! Welcome to the future!
It's pretty obvious you weren't with us 50 years ago so how would you know?
@@bobmustari6087 His point still stands, whether he was around 50 years ago or not. Of course, some might argue that while technology is advancing public opinion/government is regressing, but it's still pretty awesome. While developments like jet engines are out of reach of the average modeler, we can all enjoy the other advancements: 2.4ghz computer radios; electric power systems from sub-ounce to giant scale; cheap gasoline engines; etc.
@@maeflower5108 It's pretty obvious that you weren't in the hobby 50 years ago either. You're both making comparisons to times (probably) before you were born. Even if your conclusions were valid (they're not) you should leave such observations to those qualified to make them. Being an engineer I do appreciate the tech however I miss actually building my own models. Today, anybody with a sufficient bank account can call himself a modeler. It doesn't really matter though because it's just a matter of time until abuses by drone "pilots" will have made this hobby extinct.
@@iamram16mustari67 Not all drone pilots are irresponsible. I fly drones but i have my AMA and i registered with the government. I only fly at sanctioned fields. A few idiots ruin it for everybody. Some people get dwi tickets does that make all drivers bad...No! Ignorant comments like yours are almost as bad as the "idiots" who do dumb stuff with drones.
@@Bluembuna79 Maybe you should read my post before ragging on me. I didn't say anything about "ALL" drone pilots. Like most things in life a small minority has an enormous effect because of the degree of irresponsibility. If you want to be pissed off at someone there's plenty of blame in your own brotherhood. Go rag on them.
This was so impressive and relaxing to watch! Very awesome!
Thank you verry much ☺
Just... WOW, some people's hobbies are more work than some people's jobs!
Congrats on getting it to work! I can only guess that this engine produces much more thrust for a given fuel consumption than pure turbojets.
I like that it's powerful enough to move the trees in the background.
Glad someone else noticed...
Just a light local 500m/s breeze... :-)
Dual shaft model turbo engine, Hats off. Great piece of work.
Thank you :)
The tree behind it is catching hell. Very cool!
Looks like he had huge cr jet fighter in his house!!! love that!!!
Coolest thing I've seen all day. Throw a TR on there, and you'll be my RC hero!
Sorry, Wrong person...
Hell yeah!!! Thrust reverser would make it awesome!!!
Fuel consumption, N1, N2, Air mass flow dato to calculate specific power would be of interest.
First time I’ve seen a scale twin spool axial flow, I’m impressed
That’s gonna be one hell of an RC plane.
Next step : make the table fly.
I think he had to put some serious effort into not letting the table fly.
danmit!!! love that Air being propelled. amd it sound just like the real thing.
Wilson Chin how does it sound like a computer processor?
All it needs now is adding thrust reversers for landing. Looks really impressive.
Awesome. You can actually watch the fuel level dropping. Thirsty little bugger. Totally cool. Congratulations!!!!!!!!!!!

That is very impressive. You've done the work of multiple engineering teams.
Would you mind me asking how many hours you spent on it? And what you would estimate the sale value at? Just being curious.
Also wondering, have you done any fuel efficiency measurements? (as in energetic efficiency)
As a longtime turbocharger (snowmobile, off-road, vehicle) builder and gearhead, I love coming back and watching this....just because. Keep watching for an update.
ممكن سؤال
@@user-ug6sz1pb2t Right!!!! 🙇🏻
Don’t know what’s cooler the engine or the fuel disappearing at a quick rate.
Even put the chevron nozzle...absolutely amazing
To prevent the noise pollution
Couple of them on an ultralight could be really cool, appears to have the power and weight to be ideal
But not fuel consumption. Itd be a short flight. Adding more fuel defeats the ultralight aspect.
FAA Part 103 ultralights are limited to five gallons and the average ultralight can stay aloft for two to three hours. This thing by very rough estimate would burn through that in about an hour. Factoring in start up and taxi out and back from the active, you're probably going to get three or four laps around the pattern before you need to land, so forget about going anywhere. If you want to carry more fuel, it needs to be an experimental aircraft, and you'll need a turbine rating added to your full blown pilots license. Adding a second engine will require the same ratings you'd need for a business jet and at that point, if you have the money to throw at that kind of training, you're not going to be screwing around with an ultralight. Nice idea, but it won't ever happen.
Fantastic scale and performance.
so cool! that engine basically drank the entire bottle of that green fuel
This is probably the best toy a man could have I wish I could have one I love the sound😃
Wow the fuel. Powerful, but quite thirsty, indeed.
I wanna own one, just so I can hear it start up. Again and again
Wow! Thank you for posting.

Woow...semakin keras tenaganya semakin menguras bahan bakar, sampai secepat itu...luar biasa dorongan angin dari mesin kecil ini...keren sekali 👍👍👍
This is the next level of cool
Fuel goes quickly at max thrust, but even full sized engines only operate at max throttle setting for brief periods, such as climbing to altitude. Otherwise, they throttle back to cruise settings.
Crimson Typhoon True. But at the rate at which the engine appeared to have consumed fuel ( while at max throttle ) it would have emptied that container within a couple of minutes. Although, as I had previously stated, even full sized turbofan engines don't run at max throttle except at specific times.
And, of course, jet engine has better efficiency at higher altitude. In addition, this prototype seems to have sticky bearing. Better bearing probably will reduce fuel consumption
Uses 1,6 litre in just 5 minutes, sure is a real turbofan engine indeed.
SMGJohn lol 😂
i think bypass ratio is low
which means it consumes fuel like a turbojet
+Ali Al Kayyali
Fuel efficiency is really bad at ground level for any form of turbojet or turbofan engine because of the air resistance, they are more efficient where the air is much thinner.
SMGJohn there is no air resistance, the engine is at static conditions; where V=0
i think u meant to say that because the air density is higher so more fuel is required to burn the mass flow of air
idk tho, correct me if im wrogg
That is beautiful. Well done.
