General Electric GE90

The General Electric GE90 is a family of high-bypass turbofan engines built by GE Aerospace for the Boeing 777, with thrust ratings from 81,000 to 115,000 pounds-force. It was launched in 1990, with GE teaming with Snecma, IHI and Avio, and its main innovation was a set of 22 carbon fiber composite fan blades, a technology first developed for the experimental GE36 unducted fan, which gave twice the strength at one third the weight of titanium blades and let the engine use far fewer blades than the 38 of the CF6. It entered service with British Airways in November 1995, is one of three engine options for the 777-200 and -200ER and is the exclusive engine of the 777-200LR, 777-300ER and 777F. The GE90-115B variant, first run in November 2001, is rated at 115,000 pounds-force, and the GE9X surpassed the GE90 as the largest jet engine by fan diameter in January 2020.
