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.

The PW1000G has been selected by Mitsubishi Aircraft Corporation as the exclusive power plant for the Mitsubishi Regional Jet (MRJ). Bombardier will use the engine on its CSeries aircraft. The two new aircraft types are scheduled to enter service in 2013 (CSeries) and 2014 (MRJ), respectively. Airbus, too, will equip its A320neo with this propulsion system.

MTU Aero Engines’ share in the PW1100G-JM engine is 18 percent. In addition to the high-speed low-pressure turbine and the forward four stages of the high-pressure compressor, MTU will provide the brush seals. Moreover, the company will manufacture part of the high-pressure compressor nickel blisks for the other compressor stages of the PW1100G-JM. The company has a program stake of 15 percent in the PW1200G and of 17 percent in the PW1500G.

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.
