Pratt & Whitney Completes Testing of PurePower(TM) PW1000G Geared Turbofan(TM) Engine
Posted on: Tuesday, 3 February 2009, 14:28 CST
Successful Ground and Flight Testing of World's Greenest Jet Engine Completed on Target
The Airbus flight testing follows Pratt & Whitney's own ground and flight test program, during which the engine completed approximately 300 hours of ground testing and 12 flights on Pratt & Whitney's Boeing 747SP flying test bed. The PW1000G demonstrator engine successfully completed all test objectives.
"It is truly unprecedented to complete this amount of testing on a technology demonstrator engine," said
The most recent flight test program assessed in-flight performance, engine handling, in flight acoustics and aircraft installation of the demonstrator engine. Following the recent removal from the Airbus A340 aircraft, Pratt & Whitney will analyze the test data for engine design optimization during the next several months.
"One of a kind demonstrator engines like this are typically designed to test for approximately 100 hours," Saia said. "It is extraordinary that the PW1000G demonstrator engine completed 406 hours of testing including a total of 120 hours in flight. The engine performed exceptionally throughout the program, demonstrating both performance and reliability under extremely challenging tests such as high altitude aircraft flight maneuvers exceeding two G's of acceleration force. Thousands of data points taken during this test program will enable our engineers to optimize the engine as we enter detailed design mid-year."
The completion of the ground and flight test program clears the way for detailed design of the production PurePower PW1000G engine for the Mitsubishi Regional Jet and the Bombardier CSeries mainline aircraft. Both aircraft are scheduled to enter service in 2013.
The PurePower PW1000G engine uses an advanced gear system allowing the engine's fan to operate at a different speed than the low-pressure compressor and turbine. The combination of the gear system and an all-new advanced core delivers double-digit improvements in fuel efficiency and environmental emissions and a 50 percent reduction in noise. Pratt & Whitney has successfully tested the advanced high pressure compressor and low emissions combustor technology. The PurePower PW1000G engine is an all new centerline engine that includes next generation technology in every major module.
Pratt & Whitney has more than 16,000 aircraft engines installed with hundreds of airlines around the world. Pratt & Whitney is also a leading partner in two joint venture companies that manufacture commercial aircraft engines: International Aero Engines, which makes the V2500 for the Airbus A320 family of aircraft, and the Engine Alliance, whose GP7200 engine is in service on the Airbus A380.
Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines, space propulsion systems and industrial gas turbines. United Technologies, based in
