It is always a desire of an aerospace engineer to design an engine free of noise,eco-friendly and fuel-efficient and now the scientists and engineers seems to have sort out the solution to this much awaited design.Companies like Pratt and Whitney and Boeing are always there to extensively support the progress of such design. Design a next generation geared turbofan engine which would meet the above features.It successfully completed its first phase in the testing.
Pratt and Whitney released the engine’s current progress:
The PurePower PW1000G engine is an all new center-line engine that includes next generation technology in every major module. Pratt & Whitney targets double-digit reductions in fuel burn, environmental emissions, engine noise and operating costs, using a gear system that allows the engine’s fan to operate at a different speed than the low-pressure compressor and turbine .Pratt & Whitney’s PurePower PW1000G demonstration engine has completed the first phase of flight testing on a company-owned 747SP flying test bed.
The PW1000G engine completed 12 flights and ran approximately 43 hours with tests focused on engine performance and operability. .
“The PurePower PW1000G engine continues to perform flawlessly and has accumulated a total of 306 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 at 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 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.
“We now look forward to testing the PW1000G engine on the Airbus A340 flight test aircraft,” Saia said. “This second phase of testing, which will include approximately 75 flight hours, will focus on engine performance and acoustic testing while providing valuable installation and operating data.”
Airbus will be the first aircraft manufacturer to fly the PurePower PW1000G demonstrator engine on their own flight test aircraft.
