PurePower Engines To Power Second Generation E-Jet Family

Embraer Selects Geared Turbofan Mills For Airplanes Entering Service In 2018

The second generation of Embraer E-Jets will be powered by Pratt & Whitney's PurePower Geared Turbofan engines, the company announced Tuesday. Planned to enter service in 2018, the Embraer E-Jets equipped with PurePower PW1700G and PW1900G engines are expected to offer significant reductions in fuel burn, emissions, noise and operating costs compared to today's aircraft, according to Pratt & Whitney. With this announcement, Embraer becomes the fifth aircraft manufacturer to select Pratt & Whitney's PurePower engine.

"Pratt & Whitney's PurePower engines allow us to offer our customers the very best technology and lowest operating costs," said Embraer President & CEO Frederico Fleury Curado. "Pratt & Whitney's extensive engine testing and validation process has positioned them to meet our economic and environmental improvement targets as well as the program timeline for the new generation of the E-Jet aircraft family."

"The Geared Turbofan has proven to be truly innovative by setting new standards for fuel burn, emissions and noise reduction," said Pratt & Whitney President David Hess. "Embraer's selection of the PurePower engine is another significant endorsement of this game-changing technology."

"We are proud that Embraer has recognized the unmatched value of the PurePower engine, and we are committed to supporting a successful launch of the new E-Jet aircraft family," Hess continued. "To date, Pratt & Whitney has completed nearly 4,200 hours and more than 12,400 cycles of full engine testing for the PurePower engine family, demonstrating the benefits and reliability of the engine architecture."

Pratt & Whitney's PurePower engine uses an advanced gear system allowing the engine's fan to operate at a different speed than the low-pressure compressor and turbine. The engine maker says the combination of the gear system and an all-new advanced core delivers double-digit improvements in fuel efficiency and environmental emissions as well as a 50 percent reduction in noise.
