In 1995, the GE90 engine debuted aboard a British Airways 777 airplane along with commercial aviation's first-ever carbon-fiber composite fan blades. Early GE90 engine models boasted outputs between 74,000 and 94,000 lbs. of thrust, and today it remains the world's largest turbofan engine.
GE has continued to improve upon the GE90 design with larger variants (-110B and -115B) built exclusively for Boeing's largest 777 models (777-200LR and 777-300ER). The GE90 is now the best-selling engine for that aircraft family.
Snecma of France, Avio Aero of Italy and IHI Corporation of Japan are all revenue-sharing participants in the GE90 program.
Composite fan blade
With the GE90, GE introduced the composite fan blade-the first-ever in commercial aviation. Measuring more than four feet long and weighing less than 50 pounds, the GE90 fan blade is made from carbon fiber and a toughened epoxy matrix that delivers double the strength and one-third the weight of titanium.
The GE90 fan blade's uniquely curved design makes it larger, lighter and more aerodynamic than traditional titanium blades for reduced engine weight and lower fuel burn. Plus, the aerodynamic design allows the GE90 fan blade to pull large amounts of air into the engine, making it quieter and more efficient while generating unrivaled thrust.
A later variant, the GE90-115B fan blade, was introduced into New York's Museum of Modern Art in 2007 as a perfect example of cutting-edge engineering, design and beauty.

Rated at 94,000 lbs. of thrust, the GE90-94B engine builds on the proven
success of the early GE90 engine models and powers the Boeing 777-200 and 777-300 aircraft.
