PW1000G Flight Trials Wrap Up

Ground and flight tests on the Pratt & Whitney PurePower PW1000G are complete. Conducted on an Airbus A340-600, the flight testing program involved 27 flights and more than 75 hours in the air. The PW1000G features Pratt & Whitney’s Geared Turbofan technology, which targets lower fuel burn, operating costs, engine noise and emissions. Conclusion of the airborne trials allows design of the production PW1000G to proceed for the Mitsubishi Regional Jet and the Bombardier C-Series, both of which are projected to enter service in 2013. Prior to the joint program with Airbus, the engine underwent a Pratt & Whitney ground and air phase that involved around 300 hours of land-based testing and 12 flights on a Boeing 747SP testbed. The most recent checks with Airbus focused on engine installation and airborne handling characteristics, and in-flight performance and acoustics. Pratt & Whitney will study the test data over several months to optimize engine characteristics during the next design phase.
