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!

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.

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.

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.

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?

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

@iamjesper 2 ай бұрын

Im wondering the same

@AircraftScience 2 ай бұрын

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

@iamjesper 2 ай бұрын

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

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

@AircraftScience 2 ай бұрын

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

@technicdesigns8736 2 ай бұрын

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?

@AircraftScience 2 ай бұрын

After the starter engages, it takes approximately 45 seconds.

@xtradi 2 ай бұрын

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

@AircraftScience 2 ай бұрын

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

How does it power the landing gear?

@AircraftScience Ай бұрын

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

@miketaggart3803 2 ай бұрын

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

@balmar3 2 ай бұрын

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

@AircraftScience 2 ай бұрын

Yes. It's a brushless generator.
