Pratt & Whitney (P&W) has concluded ground testing of the PW1217 geared turbofan developed for the Mitsubishi Regional Jet.

P&W stated the engine completed more than 300h and 1,100 cycles in the testing. The powerplant is the first of an eight-engine validation and certification programme.

Elements in the latest round of tests included airfoil stress measurements and cyclic endurance testing.

The company launched testing in April of this year, and plans to continue tests on the eight engines through 2012 to support the MRJ's planned service entry in 2014.

P&W's family of geared turbofan engines is slated to power the Bombardier CSeries with a targeted service entry of 2013, the Airbus A320neo family with a debut set for 2015 and the Irkut MS-21 that has a planned service entry of 2016.
