The PurePower® engine family is intended to power next-generation commercial and business jets. The new engines offer double-digit improvements in fuel burn, pollutant and noise emissions, and operating costs. The first commercial engine to enter service will be the PurePower® PW1500G. It uses an advanced reduction gearbox that decouples the engine's fan and low-pressure turbine allowing both components to run at their respective optimum speed.
Up-to-date, five major aircraft manufacturers have selected the PW1000G to power their latest aircraft. Airbus is offering the PW1000G for the A320neo. Bombardier has chosen the propulsion system as the sole engine choice for its CSeries, as has Mitsubishi for its MRJ regional jet. Irkut will equip its MS-21 with the engine. Last, but not least, Embraer has opted for the PW1000G as the exclusive powerplant for its second-generation E-Jets.
Depending on the application, MTU’s stake in the PW1000G varies between 15 and 18 percent. The company is responsible for the highspeed low-pressure turbine and the first four stages of the high-pressure compressor. Moreover, MTU manufactures brush seals and nickel blisks for components of the high-pressure compressor for which it does not have development responsibility.
