Pratt & Whitney PW1200G family
Pratt & Whitney PW1200G is a PurePower geared-turbofan family optimized specifically for the Mitsubishi Regional Jet/SpaceJet program. MHI identifies PW1215G for the 70-seat MRJ70 and PW1217G for the 90-seat MRJ90; both use a 1,422 mm fan, 1-G-2-8-2-3 stage arrangement, 9:1 bypass ratio, and ISA+15 flat rating, with 66.6 kN and 75.6 kN takeoff ratings respectively. MHI reports FAA type certification in May 2017 and describes MHIAEL responsibility for combustor and high-pressure-turbine-disk production, final assembly, and acceptance testing. Canceled status reflects Mitsubishi’s discontinued SpaceJet program; it does not negate the engine’s certified technical identity.
