MTU Aero Engines AG recently delivered its 200th turbine center frame (TCF) for the GEnx engine.

Since 2009 the GEnx TCF – the transition duct between the high- and the low-pressure turbines – has been playing a significant role at MTU. The Munich-based company holds a 6.65% stake as a risk- and revenue-sharing partner in the GEnx program.

In early 2009 it began to modify and optimize the design, which had originally been developed by GE. In late August 2011, the first production module was handed over to GE, and nine months later the first Boeing 747-8F freighter incorporating MTU’s TCF was delivered to Cargolux.

“We’ve accomplished this milestone in record time,” says MTU CEO Egon Behle, emphasizing the importance of this module for the company. “The GEnx powers the Boeing 787 Dreamliner and is the sole engine for the 747-8, and we supply all of the turbine center frames.” The order book also reflects the significance of the project: around 1,400 orders, including options, have been received for the GEnx, with total demand estimated at about 4,400 engines.

The TCF is manufactured in MTU’s Munich shops on two highly advanced production lines. The module needs to satisfy the highest of standards, since it is exposed to extreme conditions in operation, due to its position in the engine ducting hot gases exiting the high-pressure turbine at exceeding 1,000C along structural components and pipes towards the low-pressure turbine, while keeping aerodynamic losses at a minimum.
