Pratt & Whitney’s PW1524G Geared Turbofan has completed its flight-test program, the East Hartford, Conn.-based engine company announced today. The 24,000-pound-thrust engine, destined to power the Bombardier C Series narrowbody, logged 115 hours in the air during 25 flights on Pratt & Whitney’s Boeing 747SP flying test bed since it first flew from Pratt & Whitney Canada’s Mirabel Aerospace Center outside Montreal on June 20.

“Results confirmed our earlier sea level test findings validating the geared turbofan’s overall engine design,” said Bob Saia, vice president for Pratt & Whitney’s next generation product family. “The engine operated flawlessly, enabling us to conduct double the number of flight hours we initially planned.”

Plans now call for the PW1524G to return to Pratt’s sea level test facility in West Palm, Fla., to continue testing.

Along with the more than 800 hours of full engine testing to date, Pratt & Whitney has performed critical part level and engine sub-system testing to validate designs for the PurePower engine program, including hundreds of hours of core and rig testing, design validation of the fan drive gear system, bird ingestion and fan blade containment and compressor performance for the PW1000G core. The company presently has engaged five PW1000G family engines in test and another five in the build cycle.

Pratt & Whitney plans to run a total of eight PW1500G test engines over the next 16 months and expects to gain certification in 2012, in time for entry into service on the C Series in late 2013.
