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]
The GE36 Unducted Fan (UDF), from American engine maker General Electric (GE) with 35-percent participation from French partner Snecma (now Safran), was a variation on the original propfan concept and resembled a pusher configuration piston engine. GE's UDF had a novel direct-drive arrangement, where the reduction gearbox was replaced by a low ...
The 1973 oil crisis increased oil prices in the 1970s, which caused engine manufacturers to research new technologies to reduce fuel burn, including open rotor (also known as propfan) engines. However, none of those designs made it to production aircraft, mostly due to decreasing oil prices and concerns over the high noise footprint of those ...
For the F/A-18, GE based the F404 on the YJ101 engine they had developed for the Northrop YF-17, enlarging the bypass ratio from 0.20 to 0.34 to enable higher fuel efficiency. 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 ...
In 2001, with the Lockheed Martin X-35 selected as the winner of the JSF competition to become the F-35, Pratt & Whitney's F119-JSF became the F135, while the alternate GE/RR YF120-FX engine was designated F136. On 21 July 2004, the F136 began full engine runs at GE's facility in Evendale, Ohio. The engine ran for over an hour during two ...
A propfan engine. A propfan engine (also called "unducted fan", "open rotor", or "ultra-high bypass") is a jet engine that uses its gas generator to power an exposed fan, similar to turboprop engines. Like turboprop engines, propfans generate most of their thrust from the propeller and not the exhaust jet.

The General Electric CF6, US military designations F103 and F138, is a family of high-bypass turbofan engines produced by GE Aviation. Based on the TF39, the first high-power high-bypass jet engine, the CF6 powers a wide variety of civilian airliners. The basic engine core also powers the LM2500 and LM6000 marine and power generation turboshafts.
