The General Electric GE9X is a high-bypass turbofan developed by GE Aerospace exclusively for the Boeing 777X.It first ran on the ground in April 2016 and first flew on March 13, 2018; it powered the 777-9's maiden flight in early 2020. It received its Federal Aviation Administration (FAA) type certificate on September 25, 2020. Derived from …

2020年10月19日 · In June 2019, Boeing had to deal with a GE9X issue that delayed the first-ever flight of the 777X, as the durability issues had affected the widebody aircraft engine. A month later, Boeing's Q2 2019 filing revealed that the company had delayed the first flight of the 777X to 2020 , which eventually happened on January 25, 2020.

The GE9X has one of the highest bypass ratios for a commercial engine, at 10:1, meaning that for every unit of air that goes through the combustion chamber, 10 units bypass it.

2019年6月16日 · The GE9X engine and the plane it was designed for, the 777X, will be 20% more fuel-efficient than their predecessors. Recently that powerfully efficient engine got one step closer to service when the Federal Aviation Administration certified it. The certification, a key milestone, means GE can start making GE9X engines for commercial service. ...

2020年1月28日 · To date, the GE9X program has completed more than 4,100 hours of ground and air testing, as well as 6,500 cycles.Some numbers on the superlative engine: Its front fan is a whopping 11 feet in diameter and is as wide as the body of an entire Boeing 737. It uses the fourth generation of carbon-fiber composite fan blades originally developed for ...

The size of the GE9X jet engine presented the development team with some unique challenges. For flight tests, it could only fit under the wing of a Boeing 747-400 equipped with bigger tires and landing gear struts. Fan Blades. The GE9X jet engine features only 16 fan blades on the main fan disc. The predecessor GE90 has 22 and the GEnx has 18.

ge9x计划于2019年取得适航证，以ge9x为动力的777-9将于2020年投入运营。 GE9X设计特点 GE9X是在GE90-115B与GEnx的基础上，加上近期发展的许多先进技术与材料研制出的全新高性能发动机：涵道比为10.3，比GE90-115B提高了14% (GE90-115B为9)；总压比为61，比GE90-115B提高了30% (GE90 ...

Racking up this many superlatives in one machine takes a combination of brawn and brains. Built with advanced techniques and materials, the engine is an engi-

2019年7月12日 · “The ceramics allowed us to go to 60:1 [pressure ratio] inside the GE9X,” says Ted Ingling, the general manager for the GE9X engine program. “That’s huge. As a result, the GE9X engine is not dramatically larger than engines in the GE90 family, even though it’s much more efficient.”Ingling says the new technologies and materials help ...

GE9X ENGINE The world’s largest and most powerful certified commercial aircraft engine, the GE9X is also GE Aerospace’s most efficient engine built per pounds of thrust. Incorporating advanced technologies, GE9X is designed to deliver up to 10% greater fuel efficiency than its predecessor, with emissions of nitrogen oxides (NOx) 55% below
