How A Gas Turbine Eninge Works, Bell 206 Helicopter 

Glad it helped, please share with your friends

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

+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.

Well done!! Thanks!

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.

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.

+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 .

It depends on what model but the range is around 370-700 continuous HP. Thanks for the comment, please Share & Subscribe.

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.

I have herd that they did that do reduce the overall length and make a more compact engine. If anyone else has a reason we would like to hear it. Thanks for the comment, please Share & Subscribe.

Samarth Jain There's 1 burner can in the turboshaft engine, unlike a turbo jet, or turbo fan that has multiple cans in an anular configuration around the shafts, If you center the single burner can between the compressor and turbine, it would be in the way of the shafts that connect the high and low pressure turbines to the low pressure compressor in the front, and the centrifugal compressor behind it. Also, it's easier to throw the air down the long bypass tubes then it is to have the air make a 90 degree turn into the burner can if it was located directly behind the centrifugal compressor, airflow is everything in a gas turbine engine. correct air velocity, pressure and temperature means everything. Also, having the gear box in the middle means they can center and balance the engine in the helicopter better then if the gearbox was at the end of the engine, if that was the case, you would have the engine poking out the rear or the front of the helicopter. I'm sure there's more reasons other then what I stated, but I'm tired and tired of thinking tonight. lol.

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.

@@johncuervo3019 That was not very nice! He was simply following instructions. :-) It was a nice video explanation besides.
