Pratt & Whitney's PurePower® Engine Achieves 7,600 Hours of Engine Testing Validating Engine Characteristics

SINGAPORE AIRSHOW, Wednesday, February 12, 2014

Pratt & Whitney's PurePower engine family has completed more than 7,600 hours and 17,000 cycles of full engine testing, including 850 hours of flight time. Engine testing has validated the fuel efficiency target of up to 16 percent for the Geared Turbofan™ engine architecture and has confirmed other predicted engine characteristics. Pratt & Whitney is a United Technologies Corp. (NYSE:UTX) company.

"We have now tested 31 Geared Turbofan (GTF) engines since initiating testing in September 2010. Besides confirming our predicted fuel efficiency, testing also validated our low noise levels and turbine temperatures that are all essential to delivering a reduction in engine operating cost of the PurePower GTF engines," said Dave Brantner, president, Pratt & Whitney Commercial Engines. "All of our PurePower PW1000G models will enter service meeting the fuel efficiency targets established with our customers."

The PurePower PW1100G-JM engine, which will power the Airbus A320neo aircraft, continues rigorous testing in preparation for the aircraft's first flight. The PW1500G engine for Bombardier's CSeries* airplane is powering two CSeries aircraft as it prepares to enter into service. Pratt & Whitney continues to work closely with Mitsubishi Aircraft Company, Irkut, and Embraer to finalize engine designs and complete engine certification programs to meet their airplane program milestones.

Pratt & Whitney has received orders, including options, for more than 5,000 PurePower Geared Turbofan engines from more than 50 airline and lessor customers.

Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines, auxiliary and ground power units, and small turbojet propulsion products. United Technologies Corp., based in Hartford, Connecticut, is a diversified company providing high technology products and services to the building and aerospace industries.
