Dear Readers:

As MTU Aero Engines AG’s new Chief Executive Officer, it gives me great pleasure to present the latest edition of our customer magazine. Growth in commercial aviation continues unabated this year—and will make great demands also on MTU. After all, we are playing a decisive part in the ramp-up for the production of the newest engine generations. At the same time, the aviation industry is stepping up its efforts to opti- mize the use of resources, the aim being to make tomorrow’s aircraft and engines even more fuel-efficient, cleaner and quieter. For its part, MTU, as a manufacturer of propulsion systems, has for many years been working to develop the technologies needed to further enhance the environmental compatibility and eco-efficiency of next-generation engines in a bid to drive innovation.

A truly game-changing propulsion system is the Geared Turbofan™ engine jointly developed by Pratt & Whitney and MTU. Its main application is the A320neo, Airbus’s next-generation single-aisle aircraft, which will be powered by a PW1000G-family engine. In this edition of our magazine, we are pleased to report on two key mile- stones MTU has helped achieve in this program.

A major milestone on the way to engine certification, which is slated for this year, was the series of low-pressure turbine stress tests successfully completed
