How Jet Engine Works | Part 3 : Performance

Aircraft: Boeing 777-300ER
Engine: Turbofan | GE90-115B

Aircraft systems explained.
*Full authority digital engine control (FADEC).
* Compressor surge and stall protection.
* Engine servo fuel system.
* Variable stator vane system (VSV).
* Variable bleed valve system (VBV).
* High pressure turbine active clearance control (HPTACC).
* Low pressure turbine active clearance control (LPTACC).

Major components covered.
* Electronic engine control, N1 speed sensor, N2 speed sensor, exhaust gas temperature (EGT) sensors, engine temperature probes and pressure ports.
* Low pressure compressor, high pressure compressor, combustion chamber, high pressure turbine and low pressure turbine.
* Compressor and turbine casings.
* Hydro mechanical unit, variable bleed actuator, variable bleed valve, unison ring, bell crank linkages, LVDT and thrust lever.
* Inlet guide vanes, stator vanes and stages.
* Rotor blades and stages.

probably the best engineering channel on youtube. appreciate the effort!

[VergilAckerman]

As a commercial pilot, I find this video very educational

[Tottinho]

Look, there is a lot of videos on youtube trying to explain how turbofan engine works and preforms, but you just nailed it - the best content make I've seen! Thanks!

Just one word to define your effort: "Magnificent". Highly appreciated by your work. Thanks a lot.

The sync of music with the valves shutting or opening is well made! Excellent quality overall as it was in the previous videos. Thank you!

[gnryushi]

This is incredible work. It's amazing how so much engineering resources goes into the creation of these engines.

[TC-BCN]

Great demonstration and narrative as usual, thanks a lot for your precious works.

[arkanrb]

thank you very much
greetings from Yemen

Thanks a lot our Hero..it's the best engineering channel for aircraft science and technology in YouTube...I always wait for your new updates on GE 90 engine videos. Please make more videos on B777 aircraft and engine. And you can make videos a little longer. Will wait for the next video. Hats off for your hard work..

[vgfxworks]

Now, there is no need to divide the video in parts. Thanks for the post !

[samizo]

4:13 you moved right thrust lever to reduce power on engine left xd and i really like this video

[akmureithi]

Awesome! Looking forward to the next instalment

I finished my A&P school last year and you covered pretty much all of it here. Great job. We had an engine that was used in the A10 Warthog that was a good example of this here. We had P&W PT-6 and Allison 250 turbo shaft to take apart and rebuild. The PT-6 is a turbo prop engine and the Allison 250 was used in helicopters. You should do a study on those.

[caputomaru]

What a beautiful accurate clear professional explanation.

[jjgillo]

These vids are really helpful. The graphics are excellent and well explained. Thanks

[Benny-zvuz]

Could you maybe do a in-depth video about the modern Flap/Slat mechanism? I really like your graphics👌🏼

[demal]

Nothing like the ghost of the 777 flying overhead on approach

[neromah]

this content about the ge90-115b is amazing, my only feedback is lower the volume of the background music maybe

[wdobni]

it's amazing that the engine works at all, nevermind that it works reliably and efficiently .... so much precision is required everywhere and the forces are so huge, like riding a bomb that is constantly exploding in a relatively smooth rearward direction

[mrkc]

Truly an engineering marvel! Spot on video
