The Engine Alliance (EA) is an American aircraft engine manufacturer based in East Hartford, Connecticut.[1] The company is a 50/50 joint venture between GE Aerospace and Pratt & Whitney,[1] a subsidiary of RTX. Engine Alliance was established in August 1996 to develop, manufacture, sell, and support a family of aircraft engines for new high-capacity, long-range aircraft.[2]
The main application for such an engine, the GP7100, was originally for the Boeing 747-500/600X projects, before these were cancelled due to lack of demand from airlines.
Instead, the GP7000 has been re-optimized for use on the Airbus A380 superjumbo. In that market it competed with the Rolls-Royce Trent 900, the launch engine for the aircraft. The two EA variants are the GP7270 and the GP7277.
