GE’s Dreamliner Engine Passes 50 Million Hours

GE Aerospace’s GEnx-1B high-bypass turbofan engine has surpassed 50 million flight hours. The engine, in three different thrust ratings, is one of two options available for the Boeing 787 Dreamliner family, the other being the Rolls-Royce Trent 1000. The GEnx-1B has been selected by more than 50 operators and is flying approximately 600,000 hours each month.

First running in 2006, the GEnx engine family was designed to succeed the CF6 powerplant, of which more than 8,300 were supplied for widebody airliners and transports, plus around 3,000 marine and industrial powerplant derivatives. The first GEnx variant to enter service was the GEnx-2B, which powers the Boeing 747-8. More than 2,700 GEnx powerplants of both versions are now in service, and they are approaching 75 million flight hours and 12 million cycles.
