The Qantas Group
has selectedGE Aviation's
GEnx engine as the powerplant for its Boeing 787 Dreamliner fleet of up to 115 aircraft.
The initial order is for 90 installed engines. Deliveries are scheduled to begin in 2008.
The GEnx began flight-testing on GE’s 747 flying testbed last week and has been undergoing ground tests since March 2006. Engine certification is scheduled for September 2007.
The GEnx engine will power the Boeing 787 Dreamliner and 747-8 Intercontinental and Freighter aircraft.
Based on GE90 architecture, the GEnx engine will succeed GE's CF6 engine family. It is said to provide significantly better specific fuel consumption and payload performance than GE's CF6 engines. The engine’s fan blades will utilise GE90 composite technology that GE claims has performed extremely well, with no routine on-wing maintenance required and no in-service issues for more than a decade.
