GE90

The GE90 represents GE's investment in the future of wide-body aircraft, as they put it. The General Electric GE90 combines the best proven technology from the CF6 and CFM56, NASA and military programs with advanced technology to provide a highly reliable, fuel-efficient powerplant for the next generation wide-body aircraft.

Originally the GE90 was certified in 1995 at 84,700 pounds of thrust and today's engine powers the more advanced, state-of-the-art Boeing 777 capable of flying long distances at higher speeds in a more efficient way than its predecessors.

The GE90 is available in several variants of which the GE90-115B is the most powerful derivative and is the sole powerplant for the Boeing 777-300ER. It is certified at 115,000 pounds of thrust and has broken many aviation records. The GE90-110B, a derated variant of the -115B, powers the Boeing 777-200LR and the world's most capable twin-engine freighter, the Boeing 777-200F.

In 1995 the first GE90 powered Boeing 777-200 entered service with Britsh Airways. An improved version entered 5 years later in 2000, using a 3D aerodynamic design of the high-pressure compressor to increase thrust to 94,000 lbf. In 2004, a new GE90-115B version developing 110,000 to 115,000 pounds of thrust entered into service and is the exclusive powerplant of the Boeing 777-200LR and Boeing 777-300ER models.
