Pratt & Whitney's PurePower® Engine Achieves Nearly 10,000 Hours of Engine Testing Validating Technology Maturity

FARNBOROUGH AIRSHOW, Sunday, July 13, 2014

Pratt & Whitney's PurePower engine family has completed nearly 10,000 hours and 19,000 cycles of full engine testing, including 1,400 hours of flight time. Pratt & Whitney is a United Technologies Corp. (NYSE:UTX) company.

"Testing continues to validate the Geared Turbofan™ engine's fan drive gear system in harsh environments while conducting strict, regulated trial runs," said Dave Brantner, president, Pratt & Whitney Commercial Engines. "Pratt & Whitney's engine architecture technology is robust and makes it the most mature of the new generation of commercial engines with nearly 10,000 hours of combined ground and flight testing."

The company has now tested 50 Geared Turbofan (GTF) engine builds since initiating testing in September 2010. All of the GTF engine models are on track to enter service meeting the fuel efficiency targets established with customers.

The PW1100G-JM engine for the A320neo family now includes a 2 percent fuel burn enhancement on top of the 15 percent fuel savings the engine already offers. The PW1100G-JM engine has completed over 80 percent of certification testing requirements and is on track to certify on schedule. The company has delivered two engines to Airbus.

Pratt & Whitney has delivered the first set of engines to Mitsubishi Aircraft Corporation and continues to work closely with Bombardier on the PW1500G engine and has delivered powerplants for five CSeries aircraft. Pratt & Whitney also remains on schedule to support Irkut and Embraer on their plans for regional aircraft platforms.
