GEnx

GEnx

The GEnx is GE Aviation’s next-generation engine family designed for medium-capacity long-range aircraft. Based on the proven architecture of the GE90, the GEnx is intended to succeed GE’s highly successful CF6 series, the best-selling engine family for widebodies. The engine uses latest generation materials and design processes to reduce weight, improve performance and lower noise and maintenance cost.


MTU Aero Engines participates in the GEnx program as a risk-and-revenue sharing partner and has a 6.65-percent stake. MTU is responsible for the design, manufacture, assembly and MRO of the turbine center frame. In the process, the company can draw on the experience gained with the turbine center frame for the GP7000, which has proved to be a very reliable and successful component.
