Sept. 20, 2011, Mirable, Que. - Pratt & Whitney's PurePower PW1524G engine has completed tests for the Bombardier CSeries jets, completing 25 flights with 115 flight hours at the company's Mirabel Aerospace Centre in Quebec.

P&W has been testing the engine on its Boeing 747SP flying test bed at the centre since 20 June before final assembly and testing at the facility.

The PW1500G series engine test program will continue over the next 16 months with eight test engines, before scheduled certification in 2012 and entry into service in late 2013.

PurePower is a $1 billion, 20-year development program for the global passenger jet engine market. The PurePower PW1000G series engines use an advanced gear system, allowing the engine's fan to operate at a different speed to the low-pressure compressor and turbine.

The combination of the gear system and an advanced core improves fuel efficiency as well as environmental emissions and noise, the company said.
