![]() In February 2012, GE announced studies on a more efficient derivative of the GE90, calling it the GE9X, to power both the -8/9 variants of the new Boeing 777X. It is rated at 110,000 lbf (490 kN) of thrust, which is 5,000 lbf (20 kN) less than the GE90 highest thrust variant, the GE90-115, rated at 115,000 lbf (510 kN). Derived from the General Electric GE90 with a larger fan, advanced materials like ceramic matrix composites (CMCs), and higher bypass and compression ratios, it was designed to improve fuel efficiency by 10% compared to the GE90. It received its Federal Aviation Administration (FAA) type certificate on September 25, 2020. It first ran on the ground in April 2016 and first flew on Mait powered the 777-9's maiden flight in early 2020. The General Electric GE9X is a high-bypass turbofan developed by GE Aerospace exclusively for the Boeing 777X. ![]() General Electric GE90, General Electric GEnx GE9X installed on the 777X during roll-out in March 2019 For the similarly-named engine which powers the Boeing 787 and 747-8, see General Electric GEnx.
