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.
The GE90 would face stiff competition as Pratt & Whitney and Rolls-Royce would also offer engines for the 777, the PW4000 and Trent 800, respectively. The major innovation of the GE90 was that it used 22 carbon fiber composite fan blades, technology first developed for the GE36. These blades provided double the strength at one-third the weight ...
Rolls-Royce's latest engine design for large turbofans (25,000lb to 110,000lb thrust), the UltraFan [6] includes a Powergear rated at a new high of 64MW (87,000hp) and has demonstrated this full power during testing in 2021.
The UK government granted Rolls-Royce £450 million of repayable launch investment, repaid with interest, to develop the RB.211 engine and the Trent family up to the Trent 900. [8] Rolls-Royce obtained £200 million for the Trent 8104, 500 and 600 variants in 1997, and £250 million for the Trent 600 and 900 variants in 2001.

Rolls-Royce Conway low-bypass turbofan from a Boeing 707. The bypass air exits from the fins, while the exhaust from the core exits from the central nozzle. This fluted jetpipe design is a noise-reducing method devised by Frederick Greatorex at Rolls-Royce General Electric GEnx-2B turbofan engine as used on a Boeing 747–8. View into the ...
Rolls-Royce Avon early jet engine showing 1 of 2 sets of 3 valves at the top and 1 of 2 valves at the bottom which release some air from the compressor, pressure ratio 7.45:1, for starting and low speed running. Also visible at the front is the row of bearings for the variable inlet guide vanes.
GE and competitor Rolls-Royce were selected by Boeing to power its new 787. GE Aviation's offering is the GEnx, a development of the GE90. The engine was also the exclusive power plant on the Boeing 747-8. The Lynn facility continues to assemble jet engines for the United States Department of Defense, subsidiary services, and commercial operators.
