July 14, 2008, Farnborough, U.K. – Pratt & Whitney has announced the launch of PurePower engines – a new family of next-generation commercial and business jet engines that offer double-digit improvements in fuel burn, environmental emissions, engine noise and operating costs. The announcement was made with Pratt & Whitney partners and customers during an unveiling event at the Farnborough International Air Show outside of London, England. The first engines to enter service will be the PurePower PW1000G, formerly referred to as the Geared Turbofan(TM) engine, and the PurePower PW800. Pratt & Whitney is a division of United Technologies Corp.

"Airlines and business aircraft customers want pure engine solutions that deliver economic and environmental benefits without compromises," said Pratt & Whitney President Steve Finger. "Pratt & Whitney PurePower engines employ game-changing technologies to deliver step-change improvements in environmental performance and operating costs. Pratt & Whitney is the only engine company bringing brand new technologies to the market at a time when airline customers and operators need a comprehensive solution the most."

The PurePower engine family represents a step-change from Pratt & Whitney's legacy engines, both in engine performance and in naming convention. With the first PurePower engines entering service in 2013, a new standard will be set for all future engines to build upon. PurePower engines are new centerline engines that deliver comprehensive environmental performance including double-digit improvements in fuel burn, environmental emissions and engine noise, while bringing value to airlines and operators with a double-digit reduction in operating costs. PurePower engines will also be capable of operating on alternative fuels.
The PurePower PW1000G is the exclusive power for the new Mitsubishi Regional Jet and the proposed Bombardier CSeries. Both aircraft are scheduled to enter service in 2013. The PurePower PW810C was selected by Cessna to power the Citation Columbus business jet, which is scheduled to enter service in 2014. PurePower engines are targeted to power next generation large business jets, regional jets, single-aisle aircraft and beyond.

The PurePower PW1000G uses a state-of-the-art gear system to allow the engine's fan to operate at a different speed than the low-pressure compressor and turbine, resulting in greater fuel efficiency and a slower fan speed for reduced noise. The PurePower PW1000G engine is an all new centerline engine that includes next generation technology in every major module. A full-scale PW1000G demonstrator engine recently completed a 250-hour ground test program and has begun flight-testing on Pratt & Whitney's Boeing 747 flight test bed. The engine will perform additional flight-testing on an Airbus-owned A340 later this year.


The new generation PurePower PW800 engine family raises the bar on performance and economics by taking advantage of the latest material, aerodynamic and design technologies. The engine incorporates advanced fan, compressor, turbine and low-emissions TALON(TM) combustion systems for exceptional fuel consumption, future thrust-growth capability and improved environmental performance. Detailed design work as well as advanced production preparations are underway. Pratt & Whitney Canada engineers are now entering into the detail design of various components with collaboration from suppliers and other partners.
