P&W geared turbofan engine for E-Jets
Neelam Mathews Jan 9, 2012 Embraer today announced it has selected Pratt & Whitney’s PurePower Geared Turbofan engine as the exclusive power for its new second generation of the E-Jet aircraft family. Pratt & Whitney is a division of United Technologies Corp. Planned to enter service in 2018, the Embraer E-Jets equipped with PurePower PW1700G and PW1900G engines will offer significant reductions in fuel burn, emissions, noise and operating costs. Pratt & Whitney President David Hess said: “Embraer’s selection of the PurePower engine is another significant endorsement of this game-changing technology.” The 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.
