Pratt & Whitney’s ultra-efficient PurePower tests

Pratt & Whitney announced on 19 July 2010 that it had completed testing on its full-scale PurePower engine core with more than 260 test hours, successfully validating performance and operability goals.  The PurePower family of engines is designed to power the next generation of passenger aircraft, and with entry into service scheduled for 2013, the PurePower PW1000G engine features an advanced gear system that allows the engine’s fan to operate at a slower speed than the low-pressure compressor and turbine.  The combination of the gear system and all-new advanced core delivers double-digit improvements in fuel efficiency and emissions with a 50-percent reduction in noise over today’s engines.
