Pratt & Whitney has successfully achieved Transport Canada type certification of its first PurePower Geared Turbofan engine – the PW1500G engine that will power Bombardier’s CSeries aircraft. Pratt & Whitney has conducted over 4,000 hours of rigorous engine testing since the initial engine began testing in September 2010. The PW1500G engine test program included 340 hours of flight testing on P&W’s experimental 747 Flight Test airplane. Each CSeries aircraft is powered by two PurePower PW1500G series engines. The PurePower PW1500G 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 combination of the gear system and an all-new advanced core deliver double-digit improvements in fuel efficiency, environmental emissions and noise.
