Description:
The GP7000 engine family is being developed by a joint venture 50/50 between General Electric Aircraft Engines and Pratt & Whitney to power the Airbus A380 commercial aircraft family. These high-performance, high-reliable, state-of-the-art engines are targeted on a new generation of high-capacity, long-range commercial aircraft.
GP7200 engine is derived from General Electric's GE90 and Pratt & Whitney's PW4000 engine families. They take GE90's core and PW4000's low spool heritage to achieve the requirements for new generation high-capacity, long-range aircraft while delivering lower environmental impact and lower ownership costs.
The GP7200 engines have already been selected along with RR Trent 900 engines to power Airbus A380 high-capacity commercial aircraft. The 70,000-lb class GP7270 engine will power the 560-ton class Airbus A380-800 model.
More than 300 GP7200 engines (60% of engines orders) have already been selected to power 67 aircraft ordered by Emirates (199 engines worth $3 billion to power 45 A380s), Air France, FedEx and International Lease Finance Corporation (ILFC).
The GP7200 engine completed its first flight mounted at the inboard location on the left wing of GE's Boeing 747 testbed during a three hours flight at Victorville, California, on December 3, 2004. The engine performed as expected and highly valuable raw propulsion system data on the nacelle and accessories was gathered during the test. The initial series of seven flights will last until the end of December. The second round of flight-testing will occur in the Spring of 2005.
On 14 June 2005, Korean Air selected the Engine Alliance GP7200 engine to power its five firm orders Airbus A380s plus another three aircraft options. Twenty-three engines valued at $300 million were ordered for the firm order aircraft with an option for 13 engines valued at $170 million for the aircraft options. With this order the Engine Alliance share on the A380s was set at 58 percent.
In mid-November 2005 General Electric announced that GP7200 engine surpassed all required certification tests by US Federal Aviation Administration (FAA). GP7200 engine was awarded FAA airworthiness certification on December 29, 2005. In October 2006 an A380 aircraft powered by GP7200 engines completed high altitude and hot weather testing.
