- เผยแพร่เมื่อ 5 ก.ย. 2024
- This is a brief explanation of how the gas turbine engine works that powers the Bell 206 series helicopters. Turbine engines operate of of pressurized airflow that is compressed and accelerated by the compressor and then ignited and rapidly expanded in the combustion chamber. The expanding gases turns the turbines and powers the compressor and power turbine that transmits power to the helicopter.

I’m in school right now for aviation ! Learning how to work on these and take them apart and this was absolutely the biggest help to me ! Thank you so much
Tell me... have they taught you to mix proseal??
@@uriahday747 yes they have , definitely smells like burnt hair to me
@@uriahday747 There should be a whole course section on this alone. Guys that eyeball that are ridiculous
Brilliant demonstration, a lot better than others I’ve seen. Thank you
Thanks for the explanation! I rode a B-206 today, and I was curious to how the engine worked!
Glad it helped, please share with your friends
That was hands down the best explanation of gas turbine engines
Thanks for showing us the intricate design of this engine ❤
One of the more interesting videos on TH-cam... I didn't realize that the reduction gears was such an integral part of the helicopter turbine engine.
+Afrocanuk There is also an amazing amount of reduction that takes place in the main rotor gear box. Most man rotor spin in a range of 230-600 rpm depending on the type of helicopter. Thanks for the comment please share & subscribe.
Thanks for posting. I remember those training aids from my time at Rucker in 03. Out now but moonlighting a few times a year in the B206. Good refresher!
Thank you so much, that make me know this engine is different from common Gas Turbine or general types. They designed the combustion chamber is installed in the back of the engine.
Awesome vid .. after 40 some odd years of auto mechanics .. I now understand the workings of gas turbine thank you !
Beautiful cutaway, excellent tutorial covering the basics.
I'd be very interested in you doing another video, using the same diagram, showing the starting sequence, the compressor stage, external compressor, etc and what chain of events occur in sequence. Great video sir, thank you!
I am trying to make one for the GE T-700 series. Thanks for the comment, please Share & Subscribe.
Would love to see it when you get it built. I love the Allison turboprop engine for airplanes.. amazing engines.. Small size, huge power.
Do you know what speed the final RPM of the Bell 206 is approximately? I know it varies, but stable lift, regular cruise rpm of the rotors? I know that an airplane prop, has about a 10:1 15:1 gearbox reduction on some aircraft, making final rpm approx 2200-2500 rpm.. However, helicopters have 2 transmissions I believe.. Reduction down to a base RPM of 2500ish, then down to 300-400 rpm final. I think this can vary quite a bit, but the engines have a basic cruise speed where they're most efficient. I guess this depends on every helicopter on the diamter of the blade, length of the blade, and most importantly, the magical tip speed of the rotor. I know it's extremely hard on any blade or rotor, not to mention noisy as hell, for the tip of the blade or prop to break the sound barrier, so they stay well below that speed.. But the actual final drive transmissions and gear reduction from 20,000 - 100,000 RPM in turbine engines always amazed me. Turning raw high speed whining turbine into a final drive output speed you can conceive..
I'd love to replace a twin engine Cessna 421b continental piston engines with Allison Turboprops... but the final cost is so staggering to do so, it's just not worth it. Would be an amazing conversion however.
Man, that's a whole lot of linkage to make that thing function. Thanks for sharing this!

@@nikoljes8320 No problem, whenever you want and I can also make you happy :)
The best sounding start up engines ever. Great video
Really concise and clear explanation - thanks for posting.
I work on these and the 500's as part of our company fleet of copters. This was a fantastic info-video. Good Job!
Thank you for sharing!
Thank you for this. Always wondered how the engine transfers energy to the prop.
I've seen this video before, but this semester I took a class about GTE thermodynamic cycles / component design and now it all makes sense. Great video man. Thank you for your service to this country.

Well done!! Thanks!
Cool over view of the engine and how it works, thank you.
TY for your service Sir.
That model is exceptional!!! I need one of those for my trade school kids!
Thanks for the comment, please Share & Subscribe.
That model is cool - now I can go show my mate who doesn't think a helicopter can land if the engine fails. I can prove to him that the power turbine is physically not connected to the gas generator :)
Awesom, I love how turbine engine works!
Excellent demonstration Sir!
Great explanation! I’m flying an aircraft using the Allison 250-B17
Lot of power out of 136 lbs and thanks for your service brother.
Sure is alot and to think how old the technology is where it is today. Thanks for the comment, Please Share & Subscribe.
Yeah it's really amazing. To think the SR 71 flew just a few years after the conception of jet engines.. Today's technology must be out of this world.. Hope we keep being the good guy.
So lobbyists existed back in the 1930's then?? Multi billion dollar turbo reciprocating engine contracts and maybe the fear of the technology being handed over.. I always thought Hitler had developed the first turbo jet.
Thanks for the upload!
Great video thank you very much I was wondering how a jet engine transfers power to a drive shaft... Very helpful

He should be giving credit to the manufacture Alison that made this engine. It is a very very old, but still used engine on helicopters. The Alison C-250 and other versions are still great engine.
+Lorin K Thanks for the comment please share & subscribe.
+Lorin K Is that the same company that makes heavy duty transmissions? Alison IS Very dependable!
Alison is just the gear box , Alison is the inventor of the gear box that's used on Turbins , also the same company that makes the Abrams 1 tank transmission and the Alison Transmission on Duramax trucks and Alison transmissions on commercial Diesel Semi trucks . GENERAL MOTORS actually built these turbin engines . General motors got out of the business of building turbine engines and sold the right to the engine to Roles Royce . All the Data tags are on the right side of the engine . The hot section ( turbine ) the Alison gear box , and the compressor section .
I was thinking of making a flying motorbike using that engine !
Nice! the best explanation.
Great video Man and Awesome explanation of the process!! Thanks for the upload and for your Service!!

Do piston powered helicopters still exist? I read that during the Vietnam war, the H34 was used by the Marines and it had a similar payload and spec to the Huey however it was ultimately phased out. In light civil aviation piston engines are still common but not so helicopters?
Nice Rolls-Royce engine.
Have to say it wobe better to have a tripod mounted camera and zoom in ad out giving a more stable video.
Any idea if a 250 cutaway can be found for purchase?
How many fuel injectors are in the combustor?

From what I've seen so far, the big concern for me is always going to be Compressor Stall!
Yes I like eninge too
Isn't the "Centriphetal" compressor called a "Radial" Compressor?
Great video, very informative.

great job man ! Q: is it the same as a OH-58 ? RollsRoyce engine ?
Yes and No depending on the year and model of OH-58 I suggest you do a google search on the differences and wikipedia has a good wright up on it as well. Thanks for the question, Please Share & Subscribe.
amazing that something so compact generates so much power. power output??
It depends on what model but the range is around 370-700 continuous HP. Thanks for the comment, please Share & Subscribe.

Thank you this solve problem
very well done but this engine I assume is down scaled version of the real engine,
How does the starter work? If it is electric, I bet it uses quite a bit of electrical energy to spool the turbine up to speed, to avoid a HOT start.
+Lloyd Morrison It is an electric starter and does draw a lot of amps. Most pilots will use a GPU to supplement the battery to help avoid a hot start, it makes a lot of difference in the start. Thanks for the comment, Please Share & Subscribe.
The turbine outlet temprature needle shooting on battery starts is a sight to see. Very intricate starting for jet ranger

Greetings friend ! How much it costs to buy an engine like this one or similar?
Do you know who the manafacturer of this model is?
Thanks great vid 👍
msfirefighter662
50,000 rpm is 833 rps turbofast can you imagine the engine at full speed rotating 833 rps?
information peoples don't know - russian main turboshaft engines using only axial blades. no centrifugal compressor on engine. they using centrifugal blade for tank engine and APU only.
Is the power turbine turned by the air or is there a shaft that also moves the power turbine
The power turbine is driven by the expanding gas from the combustion chamber. the PT through with a gearbox and transmission drives the main and tail rotor. Thanks for the comment, please Share & Subscribe.
