Pratt & Whitney PW6000
Pratt & Whitney PW6000 is the name of a turbofan engine with a high bypass ratio for the Airbus A318 with a thrust range of up to approx. 106 kN or 24,000 lbf .
Pratt & Whitney developed the engine with the aim of keeping maintenance and fuel costs as low as possible. However, the first tests showed that the five-stage high - pressure compressor could not achieve the target. An attempt was then made to use the six-stage compressor from MTU Aero Engines . This compressor was awarded the German Business Innovation Prize in 2002. After this integration was successful, the commitments to the future operators could be kept and the engine went into production. With this contribution, MTU Aero Engines was able to significantly increase its overall share in the PW6000 to 18% as a risk-sharing partner, and for the first time in its history MTU is producing the entire low-pressure turbine subsystem and the high-pressure compressor for an engine .
For the first time in the history of Pratt & Whitney, the final assembly of this engine is not in the USA, but at the cooperation partner MTU Aero Engines' maintenance facility in Langenhagen .
Versions
Two versions are currently available:
- PW6122A with 98.3 kN thrust (the current version for the Airbus 318)
