GP7000 – Maintenance, Repair & Overhaul

MTU participates in the development and production of the GP7000, together with Engine Alliance's joint-venture partners General Electric and Pratt & Whitney as well as Snecma Moteurs. MTU is responsible for the low-pressure turbine and the turbine center frame and manufactures components for the high-pressure turbine.

A clean-sheet design, the GP7000 engine family is powering long-haul aicraft. Next to the Airbus A380 it targets possible future Airbus and Boeing aircraft applications. The Airbus A380 powered by GP7000 engines entered revenue service in August 2008 and is setting a new benchmark in terms of reliability, fuel consumption and noise emissions in its class.
