I've seen a lot of videos on how jet engines work but none show how the engine is started, thank you for making this video

Now I can finally start my 777 to charge my phone without my pilots.
-
The engines make such a distinctive sound on start-up, I guess as resonance builds in the combustion chamber once fuel is introduced. As a 777 pilot I love these engines, they have great power. Operating in hot conductions they give massive confidence.

9 months later and this guy is still giving hearts to comments. Legend

Miss working as a turbine test technician. We tested LM, military, and commercial turbines back in the early 90s until 2001. We enjoyed dimming the test cell lights and testing the afterburners on the military jets 👍 What a spectacular show that was 😎

This entire series is just absolutely incredible. Thank you for the awesome work!
-
That was an incredibly well made video. The animations showed all the necessary details without being overly complicated, and the narration was clear and concise. Keep up the great work!

I worked for GE Aviation. I machined the front fan assemblies, high pressure turbines, & some low pressure turbine discs at Wilmington, NC. The pressure turbines are connected by a shaft to the the front fan assembly. As with all turbo fan engines, about 80% to 85% of the air being sucked into the engine bypasses the the core of the engine. This is a way to increase thrust without consuming more fuel. The GE -90 115B creates 155,000 of thrust without giving up fuel consumption such as with older aircraft. We also had a Nuclear replacement facility along with new control & fuel rods for North America.

This was one of the best videos I've seen in a while, loved all the details and actually shows and briefly explains how 1 system leads to the next, I wanna know ALL of it! Lol Thx
-
Well animated and simple to understand. Love your videos!
-
From the component locations to the shape and relative sizes of the components to how they look, this is the most accurate graphic out there!! Very nice work brother.
-
I was always waiting for such an explanation like this, which helped to clarify a lot of ideas, I much appreciate this wonderful presenting the start-up procedure.
-
Great simulation and well explained! Good work! 🙌
-
Thank you for helping me understand engine functionality for my exams, greatly appreciated!
-
Insanely helpful! Keep up the great work!
-
Perfect explanation 🔥. This video is underrated. Ive seen many videos but this clears all the doubts.
-
I have been searching for that kind of videos for years ! I can't wait for the other ones
-
Such a great way to learn about aircraft systems, engines, etc. Love your channel! You can see all the effort in every video!
-
Finally. Out of high school and on into college 202 on how a jet engine works. Thank you!

De lo mejor que he visto en mi carrera en la industria aeronáutica
