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).

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.

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

Apr 5, 2023 · General Electric GE90 engine powers the Boeing 777 aircraft family, including five passenger models (-200, -200ER, -200LR, -300, -300ER) and a freighter version (777F). The mightier GE9X powers Boeing’s brand-new 777 line, the 777X (yet to begin commercial service).

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.

Dec 2, 2019 · It was the greatest comeback in modern GE Aviation history. At 115,000 pounds of thrust, the GE90-115B would be far-and-away the “world’s most powerful jet engine,” surpassing its GE90 predecessors and all competitors.

Jul 14, 2008 · FARNBOROUGH -- GE Aviation's GE90 and GEnx continue to be extremely popular engines for widebody aircraft, such as the GE90 on the Boeing 777, and GEnx engines on the Boeing 787 and 747-8 aircraft. Below is an update on these exciting GE engine programs.

Dec 16, 2024 · The GE90 engine has a unique buzzing sound thanks to its high-efficiency fan blades and the use of advanced composite materials. This article focuses on some design elements of the GE90 that contribute to its iconic sound and operational performance.

Nov 17, 2005 · To date, the GE90-115B engine has completed more than 160,000 hours and 22,000 cycles with no engine removals and no in-flight shutdowns--a remarkable achievement for an entry into service of a new jet engine. The GE90-115B engine is currently awaiting type certification on the 777-200LR.

Jul 24, 2020 · GE Aviation’s massive GE90 engine has surpassed 100 million flight hours. In November, the aircraft engine will mark 25 years in service. Under the wings of the Boeing 777 family, the GE90 engine reached the 100-million-hour mark averaging more than …
