Apr 28, 2016· Even after 20 years, GE is still the only jet engine maker with engines using composite blades in service. Kray and other engineers are currently working on a fourth-generation blade for the GE9X engine for the 777's successor, Boeing 777X. That plane will be the largest and most efficient twin-engine jet in the world.
Turbine blades are subjected to very strenuous environments inside a gas turbine. They face high temperatures, high stresses, and a potential environment of high vibration. All three of these factors can lead to blade failures, potentially destroying the engine, therefore turbine blades are carefully designed to resist these conditions.
