The General Electric GE36 was an experimental aircraft engine, a hybrid between a turbofan and a turboprop, known as an unducted fan (UDF) or propfan. The GE36 was developed by General Electric Aircraft Engines , [ 3 ] with its CFM International equal partner Snecma taking a 35 percent share of development. [ 4 ]
General Electric Company, doing business as GE Aerospace, [5] is an American aircraft engine supplier that is headquartered in Evendale, Ohio, outside Cincinnati.It is the legal successor to the original General Electric Company founded in 1892, which split into three separate companies between November 2021 and April 2024, adopting the trade name GE Aerospace after divesting its healthcare ...
The GE36 UDF for the 7J7 was planned to have a thrust of 25,000 pounds-force (110 kN), but GE claimed that in general its UDF concept could cover a thrust range of 9,000 to 75,000 lbf (40 to 334 kN), [30] so a UDF engine could possibly match or surpass the thrust of the CF6, GE's family of widebody engines at that time.
The GE27 was developed in the early 1980s under the "Modern Technology Demonstrator Engines" (MTDE) program sponsored by the United States Army Aviation Applied Technology Directorate. [2] Sporting a 22:1 pressure ratio, which was a record for single-spool compressors at the time, the GE27 [ 3 ] was GE's unsuccessful submission to power the ...
The engine consists of a three-staged fan, seven axial stage compressor arrangement, single stage low and high pressure turbines, an augmentor, and produces maximum thrust of 16,000 lbf (71.2 kN) in the original F404-GE-400 model. The engine was designed with a higher priority on reliability than performance.
The GE Passport is a high bypass ratio turbofan. The engine is a twin-spool, axial-flow turbofan with a high bypass ratio of 5.6:1 and an overall pressure ratio of 45:1. The front fan is attached to the three-stage low-pressure compressor; the 23:1 pressure ratio 10-stage high-pressure compressor includes five blisk stages for weight reduction.
The company's first major product was an oil cooler for military aircraft. Garrett designed and produced oil coolers for the Douglas DB-7. [9] Boeing's B-17 bombers, credited with substantially tipping the air war in America's and Great Britain's favor over Europe and the Pacific, were outfitted with Garrett intercoolers, as was the B-25.
