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 Antarctic Treaty was formed in 1959 after the International Geophysical Year. The treaty shows their strength to the whole world after the 2nd world war. The treaty was designed to preserve the continent for scientific research and peace. The treaty has been successful in preserving Antarctica for over 50 years.

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.

[@TheTb11111111]

Why would they give you more confidence than in cold “conductions”?

[@grahamsalmons2027]

@@TheTb11111111 Its not that they don’t. It’s just hot conditions are demanding of power as the air is thinner. The GE’s are extremely powerful and if you have a heavy airplane in hot or high conditions they give confidence. In cold conditions, the air is denser and power requirement is not usually an issue

[@PSYCHIC_PSYCHO]

Considering that farts are pre-filled with highly pressurised air and gas, what would happen if a swollen fart got ingested into a jet-engine?

[@TheTb11111111]

@@PSYCHIC_PSYCHO you won’t be able to stand close enough to a running engine to fart into it.

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!

[@maxstr]

The narration is text to speech, and it's terrible

[@donaldhollingsworth3875]

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.

[@Russell_Huston]

Thumbs up to GE Aviation. It's still something that GE does really well. For decades GE was the great American industrial / technology leader, but over time was thought of by investors as a finance company more than anything else, a "hedge fund that makes jet engines". Nothing stays the same, but I'm rooting for GE to keep going into the future. It will be challenging. Maybe an expanding nuclear future will give GE growth opportunities. We'll see.

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 😎

[@omarhamid6821]

[@showshowtomakefreeenergyge2426]

There's a common misconception that Airplanes use gasoline to fly. However, the truth is that they use free energy. The energy comes from the sun and the wind. The sun powers the engine and the wind pushes the airplane forward. This free energy is what allows airplanes to stay in the air for long periods of time. Even if you're a plane driver, you may not fully understand how this process works. But rest assured, it's all thanks to free energy.

[@deansnipah1392]

EEC stands for Engine Electronic Control. Some planes have a FADEC (Full Authority Digital Engine Control) which is the same shit just a different name. They both gets a lot of information from other aircraft systems such as ambient pressure, outside temp, etc and they all adjust the performance of an engine automatically based on all those factors. Very expensive part!

[@Brant_Dunn]

Excellent video, I enjoyed and subscribed. Thanks! One question; how long does this entire process take from start to finish?

[@Gbluesman]

My dad was a dc-9 captain, and I can always remember long wide open schematics on the dining room table of the engine that he would always study.
