P&W Geared Turbofan Begins Phase II Ground Testing
(East Hartford, Conn., April 10, 2008) -- Pratt & Whitney's Geared Turbofan demonstrator engine has begun Phase II ground testing at the company's advanced test facility in West Palm Beach, Fla. Phase II of the ground test program will focus on engine performance and acoustic characteristics with a flight capable nacelle system prior to initiating flight testing mid-year.
The Geared Turbofan demonstrator engine has logged a total of 130 hours since ground testing began in November 2007. Running from idle to full power, Phase I testing validated the design of the fan, low pressure compressor, fan drive gear system and thermal management system to demonstrate the Geared Turbofan engine's operational efficiency.
"We have analyzed the data from the first phase of ground testing and we are delighted by the performance of the Geared Turbofan engine," said Bob Saia, Pratt & Whitney vice president, Next Generation Product Family. "The results surpassed our pre-test predictions in every major area, demonstrating the fuel burn, noise and thermal management characteristics of this new architecture. As we prepare to enter production engine design for the Mitsubishi Regional Jet and the proposed Bombardier CSeries aircraft, these results put us on track to deliver the superior fuel savings and noise reduction made possible by this new technology."
