MTU Aero Engines will be taking a 4% workshare in General Electric’s GE9X program. Germany’s leading engine manufacturer will be manufacturing and assuming design responsibility for the engine’s turbine center frame. Over the life of the program the workshare will be worth around €4.0bn in revenue for MTU. The new engine will be designed to exclusively power Boeing’s 777X long-haul airliner, which is slated to enter service around 2020. 300 aircraft are already on firm order or option. The contractual details still need to be finalized between the parties. MTU will participate in the engine’s sales and profits in proportion to its program share.
