Description: The GE90 engine was developed by General Electric to power a new generation of wide-body aircraft such as Boeing 777 and was ultimately adopted by commercial aircraft with a capacity of 100 seats/passengers or more. The first GE90 engine, GE90-85B, was certified at 84,700-lb of thrust and entered service in November 1995 powering a 777 from British Airways. Potential growth has make possible to achieve 127,900-lb of thrust by the GE90-115B model becoming the world's most powerful commercial aviation engine.

The development program for the GE90 engine is being backed by Snecma (France), FiatAvio (Italy) and IHI (Japan) as well as General Electric Aircraft Engines (USA).

The General Electric GE9X is the successor of the highly successful GE90-115B engine and is slated to power the projected Boeing 777X long haul airliner. The 100,000-lb thrust class GE9X engine will feature new materials with the first full core test scheduled for 2015. The next-generation GE9X engine incorporates an 11-stage High Pressure Compressor (HPC) with new aerodynamic technology and a 4th generation powdered alloy material that will produce a 27-to-1 pressure ratio, which will be the highest pressure ratio of any commercial engine in service. The new HPC design will significantly increase thermal efficiency and contribute a 2 percent improvement in the engine's fuel burn. Overall the new engine will offer a 10 percent improvement in fuel burn over the GE90-115B.

The GE9X includes a 132-inch diameter composite fan case and 4th generation composite fan blades; next-generation 27:1 pressure ratio high pressure compressor; a 3rd-generation TAPS (twin annular pre-swirl) combustor for greater efficiency and low emissions; and ceramic matrix composite (CMC) material in the combustor and turbine.
