GE9X

GE's GE9X is the engine to power Boeing’s new 777X long-haul airliner. The GE9X builds on the proven GE90 and GEnx architecture. The engine incorporates some of the most advanced materials and technologies and will set new records in terms of efficiency: The GE9X will be the most fuel-efficient engine GE has ever produced on a per-pounds-of-thrust basis. The engine is designed to achieve fuel-burn savings of about ten percent over today’s GE90-115B. CO2, NOx and noise emissions will also be lower. At the same time, it will be the world's largest and most powerful commercial engine when first delivered.

MTU has taken a share of four percent in the GE9X program, assuming design, development and manufacture responsibility for the turbine center frame. The first development module was delivered to GE in January 2016. MTU has many years of experience with this part, which it already contributes to the GP7000 (Airbus A380) and the GEnx (Boeing 787 Dreamliner, 747-8) engine programs.
