Progress on its geared turbofan is progressing with Pratt & Whitney initiating certification icing testing for its PurePower Geared Turbofan PW1524G engine that will power the Bombardier Cseries aircraft family with the company anticipating completing engine certification by the end of 2012.

The new engine design – a combination of a gear system and advanced core – allows the PurePower engines to deliver double-digit improvements in fuel efficiency and emissions with a 50 per cent reduction in noise over today’s engines, according to Pratt & Whitney. To date the PW1524G engine test program has run more than 1,200 hours of full engine testing – including more than 200 flight hours on its B747 flight test aircraft. “We have rigorously prepared the PurePower engine family for successful certification,” said Todd Kallman, president, Commercial Engines & Global Services. “As a result of our rig, core and full-engine testing, we are confident the PurePower engine family is ready.”

In addition to more than 1,800 hours of full engine testing, Pratt & Whitney performed critical part-level and engine sub-system testing to validate PurePower engine program designs, including hundreds of hours of core testing; design validation of the Fan Drive Gear System; fan blade for bird ingestion; blade containment; and compressor performance for the advanced PW1000G engine core.
