Pratt & Whitney, Irkut Seal PW1400G Deal for MC-21
Pratt & Whitney signed a definitive agreement with Russia’s Irkut on Tuesday to supply the PurePower PW1400G turbofan for Irkut’s planned MC-21 narrowbodies. The contract secures the PurePower engine—formerly known as the Geared Turbofan—as the only Western powerplant offered on the 150- to 210-seat series of jets. Pratt & Whitney and Irkut have chosen Belfast-based Bombardier subsidiary Short Brothers to serve as the exclusive nacelle provider for the PW1400G engine family.
Plans call for the MC-21 to fly for the first time in 2015 and enter service in 2017. Its engines will need to generate between 25,000 and 32,000 pounds of thrust.
Also chosen to power the Bombardier C Series, Mitsubishi MRJ and Airbus A320neo, the PurePower series has logged 2,900 hours of full engine testing and nearly 9,000 cycles.
The PW1217G—the engine chosen to power the Mitsubishi MRJ—began flight testing aboard one of Pratt & Whitney’s Boeing 747SP test beds on April 30 and has so far logged some 50 hours in the air and more than 1,400 hours of total run time.
Meanwhile, fourth and fifth PW1524Gs built for the C Series program flew nearly 250 hours aboard a 747SP test bed, and that variant of the engine has run more than 1,400 hours total. Pratt & Whitney plans to start ground tests of the sixth PW1524G this month and finish the model’s flight trials with a third round of tests in mid-summer.
