The major innovation of the GE90 was that it used 22 carbon fiber composite fan blades, technology first developed for the GE36. These blades provided double the strength at one-third the weight of traditional titanium fan blades.

Commercial engine with composite fan blades for double the strength at one-third the weight of traditional titanium fan blades – now a hallmark on GE Aerospace’s widebody engines. Engine reached 127,900 Ibs of thrust, a world record (since broken by the GE9X engine at 134,300 lbs. during certification testing)

GE90 variants have 22 fan blades, compared to the CF6-80C2’s 38 blades. The aerodynamic efficiency and light weight of the fan blades mean that the fan requires less energy to turn it than a fan of conventional design would. Another bonus of the use of composite materials in the GE90’s fan blades was that the intake fan is more

Recent advances in materials technology, manufacturing processes, and analytical supercomputing have facilitated the creation of jet-engine fan blades that are significantly stronger, tougher, and quieter than previous iterations. This single fan blade comes from the GE90-115B, one of the largest and most powerful jet engines in the world.

2015年2月26日 · The next-generation GE90 engine, the GE9X, will feature fewer and thinner composite fan blades than any GE widebody engine in service. To do this, GE is designing a new composite fan blade using next-generation carbon fiber composite material.

As part of the required certification testing, the GE90 successfully completed both the 2.5 and 8 lb. (1.13 and 3.63 kg) bird ingestion tests on the engine’s composite blades. In October 94, four 2.5 lb. birds were ingested with the engine running at speeds required to produce 85,000 lb. (377.8 kN) of thrust at takeoff on a hot day.

2005年10月12日 · There are 22 fan blades on the GE90-115B engine, the world's largest and most powerful jet engine, for the longer-range Boeing 777 aircraft that entered airline service in 2004. Measuring more than four feet long and weighing less than 50 pounds, the blade is made from carbon fiber and a toughened epoxy matrix.

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 115,000 lbs of ...
