PW1000G

The PurePower® PW1000G engine family is a new family of next-generation commercial and business jet engines. The PW1000G offers improvements in the double-digit percent range in fuel burn, environmental emissions, engine noise and operating costs. The first engine of the PurePower® PW1000G family to enter service will be the PW1500G. All engines of the PW1000G family use an advanced gear system which decouples the fan from the low-pressure turbine so that either component runs at its optimum speed.

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 per-cent. The company is responsible for the high-speed 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.

PW1000G-technologies

The forward stages of the eight-stage high-pressure compressor of the PW1000G consist of blisks in a novel titanium material for maximum performance and durability. Advanced coating systems ensure best-in-class performance. The three-stage high-speed low-pressure turbine of the PW1000G features advanced, aerodynamically optimized 3D airfoils for improved engine efficiency. Aerodynamic optimization between the mid-turbine frame and the low-pressure turbine permitted the first-stage stator to be eliminated to reduce part count and weight of the PW1000G engine without sacrificing efficiency.
