In February 2012, GE announced studies on a more efficient derivative of the GE90, calling it the GE9X, to power both the -8 and -9 variants of the new Boeing 777X.It was to feature the same 128 in (325 cm) fan diameter as the GE90-115B with thrust decreased by 15,800 lbf (70 kN) to a new rating of 99,500 lbf (443 kN) per engine.

For Boeing's second-generation 777 long-range versions (777-200LR, 777-300ER, and 777F), greater thrust was needed to meet the aircraft requirements. General Electric and Pratt & Whitney insisted on a winner-take-all contract due to the $500 million investment in engine modifications needed to meet the requirements, with GE receiving sole ...
The Boeing 777X is the latest series of the long-range, wide-body, twin-engine jetliners in the Boeing 777 family from Boeing Commercial Airplanes. The changes for 777X include General Electric GE9X engines, composite wings with folding wingtips , greater cabin width and seating capacity, and technologies from the Boeing 787 .
In tandem with the development of the third generation Boeing 777X, Boeing worked with General Electric to offer a 2% improvement in fuel efficiency to in-production 777-300ER aircraft. General Electric improved the fan module and the high-pressure compressor stage-1 blisk in the GE-90-115 turbofan, as well as reduced clearances between the ...
The 777X, billed by Boeing as the “world’s largest and most efficient twin-engine jet,” was supposed to enter service in 2020. It had expected to have delivered several hundred of the planes ...
The Boeing 777X is better for United's central hubs. The Boeing 777X is intended to replace the company's 747 model and the Airbus A380 as a more efficient, high-capacity long-haul jetliner.
Boeing resumed testing for its long-delayed 777X widebody jet on Thursday, with the first flight since the U.S. planemaker grounded the test fleet in August due to the failure of a key engine ...
The Boeing 777X is the world's largest twinjet, and the 777-200LR variant has the world's second longest aircraft range (behind Airbus A350-900 ULR). Other Boeing twinjets include the 767, 757 (With the latter having stopped production, but still in commercial service) and 787. Competitor Airbus produces the A320 family, the A330, and the A350.
