MTU has been a global technology leader in the field of low-pressure turbines for decades. Its technological bandwidth is enormous, extending from conventional low-pressure turbines for business jet engines to highly efficient low-pressure turbines for turbofan engines powering medium- to long-haul airliners and all the way to power turbines for heavy-lift helicopters. MTU's masterpiece is the high-speed low-pressure turbine it developed for the GTF, a key component of this new propulsion system.
For all new low-pressure turbine concepts, the overall goal is to find a well-balanced design in terms of efficiency, weight, noise, costs and service life. MTU's focus is on exploring novel, less complex constructions and looking at new lightweight materials for use at elevated temperatures. Advanced computer simulations permit the three-dimensional design of the blade duct, including side walls and fillet radii.
Turbine center frame
MTU is developing and building the turbine center frame, or TCF for short, for the long-haul aircraft engines GP7000 for the Airbus A380, GEnx for the Boeing 787 Dreamliner and Boeing 747-8, and GE9X, which is the exclusive powerplant for the Boeing 777X. This highly engineered component fulfils an important function: It routes the flow of hot gases exiting the high-pressure turbine toward the low-pressure turbine. In operation, it is exposed to extreme stresses-high mechanical loads, plus high temperatures.
