Pratt & Whitney begins testing of Advanced Core for PurePower Engine Family
Pratt & Whitney has launched testing of a full-scale PurePower engine core, marking a major milestone in the development of the new generation of jet engines.
The engine core -- which consists of an ultra-efficient high pressure compressor, a low-emissions combustor, and an all new high pressure turbine -- was designed jointly by Pratt & Whitney and MTU Aero Engines.
"The PurePower family of engines shares a common, advanced core across the PW800 and PW1000G Geared Turbofan engine models," said Bob Saia, vice president, Next Generation Product Family, Pratt & Whitney. "The PurePower engine core testing -- combined with hundreds of hours of ground and flight testing accumulated on the PW1000G Geared Turbofan demonstrator engine -- advances the maturity of this technology and brings us significantly closer to final validation and certification."
The engine core testing includes more than 1,200 individual measurements and leverages state of the art testing technologies, allowing Pratt & Whitney engineers to perform a broad scope of tests beyond what is normally possible at this stage of development. The core program aims to evaluate engine performance, operability and structural design characteristics of these key modules.
