[@stephendoherty8291]

How much additional thrust comes from the exhausts than the propellor? Could the exhaust gas not turn some smaller propellors to gain some extra thrust or generate some low end power for the plane. Since its a gas turbine and gas turbines can burn lots of fuel, can they operate different fuel types more efficiently.

[@tracemitchell2093]

on some planes like a king air it can be up several hundred pounds of additional thrust

[@mikelombart]

This is amazing! A picture is worth a thousand words, but a moving picture is worth, well... a whole lot more!

[@rainerzufall689]

You mean like... 1300 words?

[@corvoattano4777]

Actually writing a research paper about this

[@BalajiSankar]

Reverse flow is due to the reversal in flow direction in the combustion chamber

[@thanasuren23]

PT6As are basically turbo props and PT6Ts are turboshafts. Very well explained. I was a technical specialist in PWC.

[@beepIL]

Whaaaaat I never knew that, so turboprop is basically a jet engine spinning a propeller?? whaaaaaat

[@ghislainebenoit1992]

....A turboshaft rotating a propeller, which provides virtually all of the engine's thrust. That's the same thing with larger turbofans for large airliners (Airbus / Boeing) . The engine core's (gas generator + free power turbines) main purpose is to drive the (enormous) fan ahead of the core that produces over 95 % of the engine,s thrust.

[@petermcd7343]

Excellent! I am digging the explanations and the physics and engineering involved

[@blancolirio]

Excellent presentation!

[@gumbygambygimbygoo4901]

You rock for making these! Thanks Mario!

[@freepilot7732]

How much actual pound thrust is given at the exhaust?.

[@vivek6187]

Reverse flow, is not about the intake air, its the gas in the combustion chamber which is reversed.

[@guilhermerego4210]

thank you for the explanation. I have a doubt, how could the airflow pass from centrifugal compressor to the chamber combustion?

[@freepilot7732]

I appreciate your video. In the next year I'll be purchasing a new TBM 940. This place uses this engine. Type 66D.

[@DanFrederiksen]

Eclipse 550 twin jet has better fuel economy than Baron 58 and Cessna 401 piston twins. Therefore turboprops should not exist.

[@vogahl34]

Amazing! Thanks Mario

[@GLAJMAN]

Are there any exotic materials inside the PT6 engine? Like Titanium or Inconel?

[@sigistrele5835]

Thank you for your excellent explanation. I am from Austria and can understand your English very well. Greetings from Austria

[@PilotEffect]

Austria! Cool! Hi from Canada.

[@lujolasica9076]

F my profesor, this is all I needed

[@PilotEffect]

This comment made the whole yt channel worth the effort. Awesome. gg

[@Bruvva_Wu]

A benefit of it's reverse flow design is that Ice Vanes can be incorporated under the engine intake and ice chunks or other dense objects will not be able to "make the turn" up into the compressor.

[@praveshudhwani1801]

thankyou so much for this easier explanation !!

[@Stone33400]

Thank you!

[@highflyerl23]

Great video. The PT-6 is an elegantly designed engine. A good reliable design, with some neat oddities

[@heavi-armed-infadel]

Best explanation I've seen, well articulated.

[@ravikolape3671]

What is the besic price of tarboshaft engine

[@flightforfight]

Todo el secreto de un motor así está en la forma de los álabes de estatores y turbinas, en los materiales con los que están hechos y en la caja de reducción planetaria que aprovecha una muy alta velocidad de rotación de la turbina y la transforma en velocidades mucho más bajas con alto torque al eje!!!. Una maravilla tecnológica

[@PilotEffect]

yeah, it is pretty amazing technology.

[@stachowi]

Damn this was good (and short)

[@mohammedcohen]

...we used the PT6B on our Sikorsky S76B models...customers LOVED it!!!

[@earlsammesios8696]

Tsnkz sir more viboe,,,

[@jrx2662]

a banana republic!

[@cellokid5104]

Amazing explanation. I completely understand how the thing works now. Who came up with this? XD

[@georgewashington938]

PT = Popular Turboprop?

[@paulmorrisette1581]

Outstanding!!!!!

[@e7a7p7r7]

Great video.

[@jlff5381]

great video

[@JKPilot]

Thank you, that was an excellent explanatory video.

[@bath-3582]

Thank you

[@ariyarathneachala6234]

Thank you a lot

[@aminamino896]

Thank you for your excellent. I am doing university research and I want to learn more Do you recommend a book on Turboprop

[@rachaelsuliana6149]

Thank you so much...❤️❤️ loved the video

[@KoMyo-pc1mi]

❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

[@oscarschenonecruz4116]

nice

[@lilaniu552]

I am wondering why the different rotation direction for rotor of compressor and free turbine? Btw, your videos are awesome, greetings from China

[@Kaipeternicolas]

Great video! Thanks so much!

[@YG-wn7rk]

This is a very amazing video, Helped me in my pilot training!

[@roynorback7509]

Thank you Mario ! Best video on KZbin explaining Turboprops.

[@yamspaine]

Turbulence

[@maheralazzawi7814]

very good

[@yayaya1193able]

Amazing thank you for this !

[@christophereric7]

How about a video on how the gearbox works!

[@tamtam19454]

Great video, clear and straight to the point.

[@charlotteha8660]

Perfect explanations💯

[@الثااقبالصباحي]

Do you have a channel on telegram

[@PilotEffect]

no sorry

[@gregwilvert]

This is awesome, thanks man! I’ve always been confused by turboprops where you see the exhaust right behind the propeller. Now I understand - reverse flow!

[@PilotEffect]

woooord

[@TheNextAdventureShow]

Great vid. Thanks

[@joshpiliara20]

Great video... Thanks

[@readmore3634]

ratio between drive shaft & propeller (amount of reduction)?

[@tracemitchell2093]

depends on the engine but a good average is about 16:1 with 35,000 down to 1900rpm though some its 20,000:2000 so 10:1 and some its 50000:1700 it all depends on the engine and application because different props can use the same engine and you're trying to govern that prop for its max efficiency a bigger prop needs to spin slower or the tips can begin to go super sonic which leads to sudden losses in thrust

[@discoverlight]

How much thrust does the propeller itself generate in relation to the turbine? I still struggle to find an actual importance on the propeller. But I’m a newb.

[@alexc5449]

The turbine doesn't generate thrust. It powers the propeller which generates thrust for the aircraft.

[@BtcSimmer]

This is awesome! Thank you!

[@rbh-executor802]

Fabulous explanation

[@AbhishekYadav-uo3hg]

Sir why rotation of power turbine and gas generator is in opposite direction Please explain

[@zarfomania1]

I think it has something to do with balance, to reduce engine torque. If everything is spinning in one direction the plane will essentially want to rotate around it in the opposite direction if that makes sense.

[@phe9238]

Very good explanation

[@radeeskumarradeeskumar2047]

Hi

[@PilotEffect]

Hi

[@fjs1111]

Very good work with this virtual teardown!

[@PilotEffect]

cool

[@roger72715]

Amazed. Thanks

[@usaviation2281]

ABSOLUTELY BRILLIANT!

[@z400racer37]

Thank you!

[@IWreakHavoc]

it's worthy to note, although stators, according to this video, apparently do increase pressure, they also straighten the airflow, while simultaneously guiding the airflow in order to prevent a compressor stall. I said apparently because I haven't heard personally before that they increase pressure.

[@米空軍パイロット]

Neither have I, but it makes sense. The air after passing a compressor will be rotating somewhat with the direction of the shaft. By straightening the flow, you would essentially slow down the flow along that rotational axis, resulting in some increase in pressure.

[@IWreakHavoc]

@@米空軍パイロット Very true, because pressure and velocity are inverse with eachother.

[@Grumpy412]

great lesson!

[@ammarsadaka7130]

you are the best

[@Hahaa99]

Great Video

[@ehsanullah6810]

awesome videos

[@adrianestrella9539]

Good job!

[@Tropa1429]

Hello can we say that the PT6T-3 engine and the PT6A-67F engine are the same?

[@PilotEffect]

Not sure sorry

[@Tropa1429]

@@PilotEffect hello thanks for your reply, now i know the answer. And they aren't equal, i changed e mails with Pratt &Whitney.

[@thanasuren23]

PT6T is a turboshaft engine and PT6A is a turboshaft.

[@excellenceinanimation960]

Awesome!

[@asapdolphin8040]

Thanks

[@dado2i]

Fantastic video and description. Not only easy to understand but also complete and full of informations. Great job!
