P&W freezes design of geared turbofan engines
Pratt & Whitney has (Hall 5 B20-B30) frozen the design configuration of the PW1000G geared turbofans for both the Mitsubishi Regional Jet and Bombardie

Pratt & Whitney has (Hall 5 B20-B30) frozen the design configuration of the PW1000G geared turbofans for both the Mitsubishi Regional Jet and Bombardier C Series after finishing the final phase of demonstrator testing this past spring on an Airbus A340-600 testbed in and around Toulouse, France. Designated as the PW1217G for the MRJ and PW1524 for the C Series, the pair of engines will enter detailed design soon after the start of this week’s Paris Air Show, in time for first engine runs by the middle of next year, according to Pratt & Whitney next generation product family vice president Bob Saia.

Originally expected to run the first MRJ engine by the end of this year, Pratt & Whitney has juggled the schedules to take advantage of the efficiencies inherent in running two programs in parallel, according to the company.
