Airbus, Pratt Launch PW1000 Testing
The Airbus testing follows Pratt & Whitney's own ground and flight test program. In addition, it follows 12 flights and approximately 43 flight hours on Pratt & Whitney's 747SP flying test bed. The A340 flight testing, which will include approximately 75 flight hours, will focus on engine performance and acoustic testing while providing valuable installation and operating data. However, Airbus will be the first aircraft manufacturer to fly the PurePower PW1000G demonstrator engine on its own flight test aircraft. Test results will contribute to the company's long-term research and technology assessment of new engine configuration developments.
"We are delighted to partner with Airbus on flight testing the PurePower PW1000G engine," said Todd Kallman, president, Pratt & Whitney Commercial Engines & Global Services. "Demonstrating the Geared Turbofan technology throughout its entire operating envelope using the Airbus A340 flight test aircraft, combined with the tremendous experience of the Airbus flight test team, will provide us with valuable installation and operating data to further evaluate the performance of this new engine architecture."
"The PurePower PW1000G engine continues to perform flawlessly and has accumulated more than 300 hours of ground and flight testing to date," said Bob Saia, Pratt & Whitney vice president, Next Generation Product Family. "The first phase of our flight test program included full power takeoffs, in- flight performance up to 40,000 feet altitude, engine operability including in-flight starting, and engine operation during extreme aircraft maneuvers. The PW1000G engine's performance has met all of our pre-flight performance targets."
The PurePower PW1000G demonstrator engine, with Pratt & Whitney's patented Geared Turbofan(TM) technology, completed a 250-hour ground test program in May. The ground test program follows thousands of hours of development testing accumulated on 16 technology rigs at Pratt & Whitney and partner facilities around the world.
