Description
The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aviation for the Boeing 777, with thrust ratings ranging from 74,000 to 115,000 lbf (330 to 510 kN). It entered service in November 1995. Currently the world’s largest turbofan engine, it is one of three options for the 777-200, -200ER, and -300, and the exclusive engine of the -200LR, -300ER, and 777F.
History
The GE90 was launched in 1990 by General Electric (USA) associated with Snecma (France), IHI (Japan) and Avio (Italy). Developed from the 1970s NASA Energy Efficient Engine, the 10-stage high pressure compressor develops a pressure ratio of 23:1, an industry record. The GE90-115B fan is an advanced design made from composite materials and featuring swept rotor blades.
At least one technical paper presented on behalf of one of GE's project partners indicates that further thrust improvement programs will be promoted should a market for higher thrusts arise. For comparison purposes, the Boeing 747-400's largest engines produce 63,300 lbf (289 kN) of thrust. It is therefore likely that the next version or successor of the Boeing 777 will be powered with a later version or derivation of this engine and will produce twice the thrust of the most powerful fitted to the venerable 747.
