Pratt and Whitney (P&W) will begin full engine testing of its PurePower PW1000G geared turbofan for the Bombardier CSeries narrowbody during the third quarter of this year.

"The first CSeries engine will go to full engine testing in August," P&W vice-president next generation product family Bob Saia recently told ATI in Dallas.

The PurePower family features two engines - the conventional PW800 and the PW1000G geared turbofan - and both share the same core.

The PW800 is designed to power corporate jets, while differing thrust classes of the PW1000G will power the CSeries and the Mitsubishi Regional Jet (MRJ).

Core testing has been underway since late last year. "The full MRJ engine test is in October," says Saia.

FAR 33 engine certification for the PW1000G is expected in 2012.

Both the CSeries and MRJ are expected to enter into service in 2013. P&W claims the PW1000G offers a 15% lower fuel burn than current engines.
