GEnx

The GEnx is GE’s next-generation engine family designed for medium-capacity long-range aircraft. Based on the proven architecture of the GE90, the GEnx succeeds GE’s highly successful CF6 series, the best-selling engine family for wide-bodies.

MTU Aero Engines participates in the GEnx program as a Risk and Revenue Sharing Partner with 6.5 percent. MTU is responsible for the design, manufacturing and assembly of the turbine center frame (TCF). MTU could further develop its experience gained by GP7000 TCF design, which proved to be a very reliable and successful component.

The Turbine Center Frame is one of the major structural components of the GEnx engine and contains one bearing of the engine rotor. Besides this structural task it fulfills an aerodynamic function: it is the transition duct for the hot gas stream from the high pressure turbine to the low pressure turbine. These different functions (high stress areas and hot environment) lead to high requirements towards materials and design.

With latest generation materials and design processes the turbine center frame is designed with reduced weight compared to previous generation engines, which makes its contribution to the success of the GEnx engine, especially in terms of reduced fuel consumption by lower weight. Compared to the CF6, the GEnx engine offers an overall 15 percent improved fuel efficiency, which also means 15 percent less CO2 emissions.
