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] Development was cancelled in 1989.
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 commercial version of the T407 was the GLC38 (General Electric/Lycoming Commercial 38), which was unsuccessfully offered for several turboprop airliners in the late 1980s and early 1990s. [ 2 ] The new T408 ( GE38-1B ) is slated to power the new Sikorsky CH-53K King Stallion three-engined helicopter for the US Marine Corps.
General Electric offered to develop the GE90-115B engine, [8] while Rolls-Royce proposed developing the Trent 8104 engine. [9] In 1999, Boeing announced an agreement with General Electric, beating out rival proposals. [8] Under the deal with General Electric, Boeing agreed to only offer GE90 engines on new 777 versions.

The Pratt & Whitney/Allison 578-DX was an experimental aircraft engine, a hybrid between a turbofan and a turboprop known as a propfan.The engine was designed in the 1980s to power proposed propfan aircraft such as the Boeing 7J7 and the MD-91 and MD-92 derivatives of the McDonnell Douglas MD-80.
The General Electric F404 and F412 are a family of afterburning turbofan engines in the 10,500–19,000 lbf (47–85 kN) class (static thrust). The series is produced by GE Aerospace . Partners include Volvo Aero , which builds the RM12 variant.

A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
Contra-rotating propellers Contra-rotating propellers on the Rolls-Royce Griffon-powered P-51XR Mustang Precious Metal at the 2014 Reno Air Races. Aircraft equipped with contra-rotating propellers (CRP) [1] coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston engine or turboprop engine to drive a pair of coaxial propellers in contra ...
