Pratt & Whitney's new generation PurePower engine family has completed more than 7,600 hours and 17,000 cycles of full engine testing, including 850 hours of flight time, company announced during the Singapore Airshow.
P&W said its engine testing has validated the fuel efficiency target of up to 16 percent for the Geared Turbofan™ engine architecture and has validated other predicted engine characteristics like low noise levels and turbine temperatures that are essential to delivering a reduction in engine operating cost. P&W has tested 31 Geared Turbofan (GTF) engines since initiating testing in September 2010.
P&W Pure Power engine is a high-bypass geared turbofan engine family, features a gear system in between the engine fan and the low pressure compressor allowing each of the modules to operate at their optimum speeds. This enables the fan to rotate slower and while the low pressure compressor and turbine operate at a high speed, increasing engine efficiency and delivering significantly lower fuel consumption, emissions and noise. This also reduces engine stages and parts for lower weight and reduced maintenance costs.
The PurePower PW1100G-JM engine, which will power the Airbus A320neo aircraft, continues rigorous testing in preparation for the aircraft's first flight. The PW1500G engine for Bombardier's CSeries airplane is powering two CSeries aircraft as it prepares to enter into service. Pratt & Whitney continues to work closely with other aircraft manufactuers like Mitsubishi Aircraft Company, Irkut, and Embraer to finalize engine designs and complete engine certification programs to meet their airplane program milestones. Pratt & Whitney has received orders, including options, for more than 5,000 PurePower Geared Turbofan engines from more than 50 airline and lessor customers.
