Paris, France — Pratt & Whitney Canada launched its PW1500G PurePower engine line with the first test flight its PW1524G, earmarked for the Bombardier CSeries aircraft. The engine flew its maiden flight on Pratt & Whitney Canada’s 747SP flying test bed at at its Mirabel Aerospace Centre, in Mirabel, Quebec. Open since May 6, this facility will house final production assembly and test for both the PurePower PW1524G and PurePower PW800 family.

In addition to engine testing, Pratt & Whitney has performed critical part level and engine sub-system testing to validate designs for the PurePower engine program, including design validation of the Fan Drive Gear System, fan blade for bird ingestion and blade containment and compressor performance for the advanced PW1000G core.

The PurePower PW1000G series engines use 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 a new core deliver double-digit improvements in fuel efficiency, environmental emissions and noise, the company says.

The PW1500G engine test program will run a total of eight test engines over the next 18 months with engine certification scheduled for 2012. Entry into service is scheduled for 2013.
