During my career, I worked on several aircraft projects for Boeing, including the Advanced Tactical Fighter program, the Boeing 777, and the 787 Dreamliner. It was always interesting and challenging.
N747GE is a Boeing 747 aircraft that was used by General Electric Aircraft Engines (now known as GE Aerospace) as a testbed for several of the companies jet engines between 1992 and 2017, including the GE90 for the Boeing 777, at the time, the world’s largest jet engine.
Aircraft engine performance refers to factors including thrust or shaft power for fuel consumed, weight, cost, outside dimensions and life. It includes meeting regulated environmental limits which apply to emissions of noise and chemical pollutants, and regulated safety aspects which require a design that can safely tolerate environmental hazards such as birds, rain, hail and icing conditions.
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.

WASHINGTON (Reuters) -The Federal Aviation Administration plans to convene a review board in the coming weeks to consider safety concerns about engines on Boeing 737 MAX airplanes after two bird ...
Boeing also withdrew a safety-exemption request related to the Max 7's engine de-icing system earlier this year, as it faced more scrutiny after January's Alaska Airlines blowout.
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 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 ...
