      Most turbine engines work basically the same way. There are a few variations in bypass, and combustion chamber types but pretty much the same basic principals as this. Can, Can-Annular, and Annular are the 3 main combustion section types. Can is used in smaller engines like APUs and GPUs and on some small turboprop engines. Can-Annular are older types used in turbojet engines like the JTD-4, and Annular are used in most modern high bypass engines. Though can-annular are still used by in drastically fewer numbers than they used to be. In fact I used to laugh at one particular episode of Star Trek The Next Generation episode because they used a bunch of can-annular cans for set decoration as "scavenged parts" from derelict ships. Most people would have no idea what they were looking at though.

    This was a wonderful explanation of the operation "cycle" of the engine. As an aircraft maintenance engineer, I started my career working on Beechcraft King Air 200, 250, and 350. I've performed many many "HSI's" 10:35 (hot section inspections) on these PT6 engines, where we split the engine at the point between the CT(compressor turbine) and the 1st stage PT(power turbine) .
    It's always amazing to see the cutaway of the exact engine you'll be working on, which is generally only located at the manufacturer's approved course-instructing facilities.
    Fun fact: Only approximately 30% of the air in a turbine engine is used for combustion. The other ~70% is used for cooling!
    Oh, I also managed to salvage an unserviceable gas generator (the inside of which is pictured at 4:04 with the diffuser ducts/vanes) and installed a glass top on it to serve as a coffee table :)

  • @eltfell
    @eltfell Год назад +6

    The air is NOT accelerated in the compressor, although the duct gets more and more narrow and the Venturi effect should kick in. That's because the blades on the rotors and stators build up a decelaration grid. The speed of the airflow remains more or less the same while passing the compressor. The compressor is not about to accelerate the air, but to compress it. BTW, a centrifugal stage is used when the ratio of blade length and width of the gap between blade and channel would get too big.

    • @calvinnickel9995
      @calvinnickel9995 Год назад +1

      The compressors do accelerate the air tangentially. The stators are there to reduce the tangential velocity and convert it into static pressure.
      A centrifugal compressor is used to make a compact engine as it’s far more suited to a reverse flow combustion chamber (not to be confused with reverse flow engine) which allows the compressor turbine to be mounted on a very short shaft between it and the compressor.

    • @calvinnickel9995
      @calvinnickel9995 Год назад

      A centrifugal compressor is also cheaper to make, more resistant to compressor stalls, and if it’s the first stage more FOD resistant.

I started out with the PT6-6/6A and I stayed with the program up until the -27 was fielded. Worked with companies such as GM, Miles Lab, Upjohn, Marathon Oil but to name a very few. My territory included Mighigan, and N. Ohio. Also did a stint at Rockwell in Colmbus, Ohio when we we trying to get the contract for the OV-10A that had engines turning in opposite directions to counter the prop torque.

    You’re really making my life man. I’ve been searching for detailed explanation (for ex how to air compressed) but never find one until now. Thank you so very much. I hope we can have one like this for the helicopter turboshaft also. Thank u Captain ❤❤❤❤

    Impressive engine explained in laymans terms helping a curious mind on the way to better understanding. Thank you, Captain Joe, wish there was more people like you, more enganged in the matter at hand than the drone of their own voice when explaining stuff. I’ve seen the Pilatus Porter and what it can do. Now I know how the engine works that makes much of the Porters abilities possible.

    That was great. I thought I understood this incredible engine before, I didn't.... Now, it makes sense. Thank you CJ for all the insight you give, I've always loved aircraft and so appreciate all the common sense depth you give.

    You have cleared up the inlet confusion I was experiencing. It wasnt by any means obvious where the inlet was situated. Thank you. They are an excellent and fuel-efficient engine type, with the reliability and longevity of jet engines, and a smaller, slimmer, footprint advantage.

    Retired from Alaska Air's regional service, Horizon Air, just recently. Went from AMT into Maint QC and eventually to their Propulsion Shop and worked on the RR Spey, GE CF34's and the P&W 123, 125 and 150 Turboprops. These Amazing Turboprop Engines are also Reverse Flow but put out 2300, 2500 and 5000 Shaft Horsepower to the Prop. The 150 swings a 13.75 ft diameter Dowty 6 Blade Prop and are used on the Dehavilland Q-400. What I would ad here is that after 100's of Borescopes (internal microscopic inspection), performed on these P&W Turboprops, I was amazed at how damage tolerant they are. Damages are usually confined to Combustion Liner wear and Compressor section Blade wear from normal use. P&W has every imaginable type of wear damage Recorded and Mapped for reference and all are well documented and tested for continued service. The more wear found, the more often the Borescope procedure. These are Fabulous engines that have been around a while and contain the Technology that has made the new PW1000G Geared Turbofan so successful. These GTF engines have 40 yrs+ of development behind them and offer a 15% savings in fuel economy over normal Turbofans. It was because of this fuel saving P&W GTF, used on the Airbus A320, that Boeing needed to provide something competitive, and thus, the 737 MAX was born. Boeing's answer to saving fuel was to mount the 737's existing GE CFM56-78 Turbofans UP further into the Wing, and Inboard as well, giving a considerable boost in fuel savings by reducing Drag. The downfall was that the faster this configuration of 737 flew, the more the plane wanted to climb and go "out of trim". Thus they had to invent the MCAS computer driven auto trim system (maneuvering characteristics augmentation system), to prevent the plane from climbing out as speed increased. That's where they got into trouble w/ the MAX. They Didn't inform the Pilots about this AutoTrim system, nor did they give a way for the Pilots to override it in case of a Pitot Tube (speed sensor) failure.

    There is a regional airport very close to my work, and you can always tell when a turboprop is on the line due to its distinctive sound when taking off. Very cool!

    Sir, I am a retired machinery engineer for a major oil company and worked with gas turbines, hot gas expanders, axial/centrifugal air compressors and high pressure to low pressure turbo expanders for 39 years and this by far is the best explanation I have ever seen, you did a fantastic job. I really enjoyed listening to your explanation.

    I love the sound of turboprops spooling up. That high frequency sound underscored by a smooth base thrum gives me goosebumps. The only thing that beats it is the bodily acoustic overlapping resonances of rocket launches. Auditory heaven that's worth the eardrums.
