The background music during engine startup is amplifying the power and strength of the b777 engine.

The dramatic music check valve is opened so it can improve starter performance.

I loved the transition to your engine-series background music when the animation shifted temporarily to the left engine start. I appreciate how you’re putting a lot of thought into the structure and flow of these videos!

Thank you very much!

Another spectacular video, the quality of the video associated with the description of the system is brilliant. I can say that it enriches and facilitates learning far beyond the airplane manual.

So much engineering ingenuity is taken for granted in our daily lives. These videos shed light on how science and engineering provide the quality of life that we enjoy.

This is amazing. I felt like I should be taking notes, as there would be an exam tomorrow! This is drinking from a firehose level, nothing dumbed down for layman consumption.

Extremely amazing & informative video, thank you. 🙂

From a pilot, thanks for such well done research, and world class presentation. If the same people who did this presentation, taught my aircraft transition class/ground school, ...learning the aircraft systems during my one month stuck in a classroom would have been much more enjoyable :) ... and efficient, with regards to learning, and command of the information.

Absolute cinema!

Fantastic video and graphics!!

Excellent video. Learned a lot about apu.

Beautiful

Special thanks to you for your amazing explanation .

Seems simple. Very well done video.

love your video, wait to watch part 3.

Wow man this video is super amazing

very weel! nice !

Wow! Super Graphical Schematics on Everything, almost.

Thanks !

Nice videos sir please do morw

I can't even fathom how many hours went behind making it

Amazing 😍😍

Amazing and spot on animation, I just have a question doesn’t the right engine gets started up with the bleed air from the left engine?

Keep it up Bro.

Thanks bro

Is it from engine 1 bleed to engine 2??? Or that's the way by 777 to start engine 2 from APU?

The APU bleed is used to start the main engines. A cross-bleed start is carried out only when the APU bleed is unavailable.

@@AircraftScience do you know why this is the way? Does the apu produce more bleed air than the single engine?

Part one?? Got a link for it?

You have made an amazing job on explanation of a sophisticated engineering marvel in such a comprehensible way. Looking forward for more contents from you. Btw, how much time is it required for APU to reach 100% RPM?

After the starter engages, it takes approximately 45 seconds.

How does the efficiency of apu compare with similar power ICE generator?

Great illustrations. Are there illustrations for the way to produce the air that pilots/passanger breathes in an airplane?

I will be making a series on the air conditioning system. Stay in touch with the channel.

What would be the pneumatic start option for the APU itself...?

@AircraftScience

The APU pneumatic start will be covered in the next part.

Why cant we feed main rotor directly? Whata the purpose of exciter there ?

Now understand in depth how does an airliner jet engine works

is part 3 being prepared or is there anywhere else where I can rent it or watch it?

I'm working on it.

Can I switch off the apu when the airplane is in sky

How does it power the landing gear?

@AircraftScience

2 ай бұрын

When required, the APU can power the aircraft's hydraulic system and help operate the landing gear.

Please help me with the companies parts of Airplanes

I was under the impression that once an engine is running, one uses that bleed air to start the other engine.

Fascinating stuff. No slip rings, no commutator, I guess it's more reliable this way?

Yes. It's a brushless generator.
