2022年11月17日 · Larger than a Boeing 737 fuselage, the GE9X fan diameter enables a higher bypass ratio for maximum efficiency. The GE9X has six less fan blades than the GE90 engine. This maximizes air flow and minimizes drag, contributing to the engine's fuel burn and noise emission advantages.

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.

Largest turbofan engine in the world. Most fuel-e cient. Quietest.* With the lowest emissions in its class. 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-neering marvel whose beauty lies in the details. Have a look.

通用电气GE9X（英語： General Electric GE9X ）是通用电气研制的大涵道比涡轮风扇发动机，用于波音777X机型上。 该发动机由 通用电气GE90发动机 衍生而来，燃油效率将得到约10%的提升。

在经过近5000个小时和8000个循环的测试之后，ge公司宣布其ge9x型号发动机获得了 faa适航许可证 ，将正式安装在 波音777 飞机上运行。 GE9X也正式从他的前辈GE90手中接过“世界最大商用航空发动机”的桂冠。

2016年4月28日 · At nearly 13 feet in diameter, the GE9X is the largest jet engine ever built. It is wider than the fuselage of a Boeing 737. Or, as the publicists at General Electric put it, if Kobe sat on...

GE9X 发动机将为新型777-9飞机提供动力，运用了业界领先的创新技术。 采用第四代碳纤维复合材料风扇叶片；集成65个耐热陶瓷基复合材料（CMC） 部件提高部件强度；利用增材制造（3D打印）将300多个零部件组合成7个3D打印部件减轻发动机质量；燃油效率比上一代GE90发动机提高了10%。 GE9X发动机已经完成5000h和8000循环地面测试，在波音747试验台上进行了72次共计400h的飞行测试，生产型 GE9X 发动机的交付是777-9宽体飞机项目的一个关键里程碑。 《 …

The GE9X engine contains GE Aerospace’s latest generation of carbon-fiber composite, ceramic matrix composite (CMC), and additively manufactured components. Composite and additive parts are lighter than the traditional metal parts they replace. CMCs are also stronger and more heat resistant than their metallic counterparts. TAPS Combustor System

2020年1月28日 · It is powered by the GE9X engine, the largest and most powerful commercial jet engine ever built. The pilots in the cockpit on the airplane’s first foray had engines capable of providing a record-breaking 134,300 pounds of thrust available on each wing. There was plenty of pride back down on the ground.

The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aerospace for the Boeing 777, with thrust ratings from 81,000 to 115,000 pounds-force (360 to 510 kilonewtons). It entered service with British Airways in November 1995. It is one of three engines for the 777-200 and -200ER, and the exclusive engine of ...
