The engine has two contra-rotating rotors (fans) on the outside of the engine nacelle, either at the front of the assembly ("tractor") or at the rear ("pusher"). Both pusher and tractor open rotor designs form part of Rolls-Royce's long-term "15-50" vision, which is examining various architectures to tackle the 150 seat-aircraft market.
Chosen to power the Falcon 2000 in 1990, the engine was also first run in May 1990, [1] and it was first flown on a Boeing 727 testbed on 31 August 1992. [2] The CFE738-1 made its inaugural flight on a Falcon 2000 prototype on March 4, 1993.
In 1982, Detroit Diesel Allison (DDA) prepared a new engine design to enter the United States Army's Modern Technology Demonstrator Engine (MTDE) competition, which was expected to be developed into the powerplant for the United States Navy's JVX experimental tiltrotor aircraft program (which would eventually become the Bell Boeing V-22 Osprey).

Boeing was one of the first aircraft manufacturers to realise the full potential of the CFM56 engine. Boeing president Thornton Wilson contacted Neumann and Ravaud in 1977 with a proposal for an agreement to replace the engines of the 707 using the CFM56. On March 17, 1977, flight testing of the CFM56 began on the Caravelle flying testbench.
Boeing T50 / Model 502 The Boeing T60 (company designation Model 520 ) was a family of small turboshaft / turboprop engines produced by Boeing , based on Boeing's earlier Model 500 gas generator and Model 502 (T50) turboshaft engines.
The General Electric GE4 turbojet engine was designed in the late 1960s as the powerplant for the Boeing 2707 supersonic transport. [ 1 ] [ 2 ] The GE4 was a nine-stage, single-shaft, axial-flow turbojet based largely on the General Electric YJ93 which powered the North American XB-70 bomber. [ 3 ]
The panel, created after fatal Boeing 737 Max crashes in 2018 and 2019 but before the recent incident in which a door plug blew out the side of an aircraft, found “gaps in Boeing’s safety ...
The XB-38 was the result of a modification project undertaken by Vega (a subsidiary of Lockheed) on a Boeing B-17 Flying Fortress to fit it with liquid-cooled Allison V-1710-89 V-12 engines. It was to be an improved B-17, and an alternative if the normally fitted air-cooled Wright R-1820 radial engines became scarce. Completing the ...
