PW2000: Powering the Boeing 757

MTU has been working in cooperation with Pratt & Whitney on developing and manufacturing the PW2000 engine family since 1979. These engines are used in both the commercial and military sectors, particularly in medium- and long-haul operations.
 

MTU’s involvement in the PW2000

MTU’s program share of 21.2 percent in the construction of this successful engine comprises the development of the low-pressure turbine and the turbine exit case as well as the production of the most important parts of the low-pressure turbine and other high-quality components. MTU’s low-pressure turbine for the PW2000 was the first the company had developed independently for a commercial application. MTU Maintenance Hannover also offers complete maintenance services. MTU provides technical and logistical support for the F117 military application, which powers the Boeing C-17 Globemaster.
