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 ...

Powering the twin-engine Boeing 777 aircraft, the GE90 engine combined record thrust and high reliability with lower noise, emissions, and fuel consumption to become an iconic jet engine recognized worldwide for its size and innovations.

ge90-115b这一型号的发动机是吉尼斯世界纪录所记载的世界上推力最大的航空发动机，地面台架试验中曾经达到过56.9吨的最大推力。 GE90在1995年11月正式投放商业市场，用于波音777系列客机。

通用電氣GE90（英語： General Electric GE90 ）是由通用電氣公司旗下的通用電氣航空所製造的高涵道比 渦扇發動機系列。 在GE90系列中，GE90-115B這一型號的發動機是 金氏世界紀錄 所記載的世界最高推力的民航發動機，試驗推力可達127,900磅（569 千牛頓 ）（將被 GE9X ...

在ge90系列中，ge90-115b这一型号的发动机是金氏世界纪录所记载的世界最高推力的民航发动机，试验推力可达127,900磅（569千牛顿）（将被ge9x以134,300磅/597.4千牛顿的纪录取代。

The GE90 standard’s HPC is central to the engine’s high pressure ratio. It has 10 stages, four fewer than the CF6-80E1. Despite its shorter length, the GE90’s HPC design allows it to generate a high enough pressure ratio. This reduces the number of stages, and therefore the number of blades and vanes. GE also developed the GE90’s

Yüksek motor teknolojisine üstün TEI katkısı. GE90, Boeing’in 777-200, 777-200LR, 777-300, 777-300ER ve 777 Freighter uçaklarında kullanılmakta olup dünya genelinde 70 farklı operatör GE90 motorlarını tercih etmiştir.

Launched in 1990, the GE90 engine is GE Aerospace’s first engine in the 100,000 pound thrust class and became the most technologically advanced commercial turbofan engine in 25 years.

2018年9月23日 · 在 ge90-115b中,除仍然采用了基准发动机中的 n3r、n4与 n5支点结构外,n1支点还采用了折返式弹性支座,且支座与轴承外环也做成一体。

2024年7月30日 · The GE90 was the first commercial engine with composite fan blades for double the strength at one-third the weight of traditional titanium fan blades – now a hallmark on GE Aerospace’s widebody engines. It was also the first engine to receive FAA approval for an additive manufactured compressor sensor.
