GEnx facts and figures at a glance

The GEnx engine powers the Boeing 787 Dreamliner and Boeing 747. MTU has a 6.65-percent workshare in this program and is responsible for the development, production, assembly and maintenance of the turbine center frame (TCF).


3,000 individual parts are installed in the turbine center frame (TCF) of the GEnx engine. MTU Aero Engines has a 6.65 percent workshare in the GEnx program and is responsible for the development, manufacture, assembly and maintenance of this important component. The engine powers the Boeing 787 Dreamliner and the Boeing 747.

1,000,000 flight hours have been clocked up by GEnx engines for the air freight company Cargolux. The airline from Luxembourg was the first in the world to reach this milestone. With entry into service of its first Boeing 747-8F more than five years ago, ­Cargolux also became the launch customer of the innovative GEnx engine powering the jet. “This proves how outstanding the engine’s technology and performance are,” says Tom Levin, General Manager of the GEnx program at GE Aviation.

Over 1,300 engines are ­currently in operation, powering aircraft for 51 different customers. The planned sales volume to the end of the GEnx program is around 3,600 units. Since March 2017, the Turbine Center Frame has been manufactured and ­assembled at the MTU site in Poland. The TCF has been repaired exclusively in Hannover since 2015—in other words, MTU covers the entire lifecycle of the component.

A look inside an engine test cell

11.2017 | Development tests and production accept­ance tests have dif­ferent goals and require different activities but, in both cases, the steps the engine goes through in the test cell are always the same.
