The Crazy Evolution of the World Largest Jet Engines Ever Built
Sponsored
Welcome back to the our channel for details on the evolution evolution of jet engines powering the world’s largest airplanes. GE9X is probably the most beautiful engine I've ever seen. Absolutely stunning amount of effort, testing and engineering to make an engine that size. Its interesting to see RR have ventured into the smaller jet engine market, they usually don’t produce for narrow body aircraft. Nice video, but the GENX is not the most powerful engine at the thrust stated in the video. Among the current 777's engine options is the GE-90 turbofan, which produces 125,000 pounds of thrust, much of it via the front fan (the bypass) rather than the combustor; this occurs on a test stand. In service mounted on the aircraft, the engine is derated to 110,000 lb o thrust, still higher than the GENX. But the new 777-X's design and aerodynamic efficiency allows it to haul a higher payload with a slightly lower thrust engine, which means substantial fuel savings and lower emissions. Whoopee, the electric airplane can fly 40 minutes before having to recharge, which takes how long? Congratulations the plane can taxi, take off and immediately have to land.
