The Pratt & Whitney Canada PW100 engine family is a series of 2,000 to 5,000 horsepower (1,500 to 3,700 kW) turboprops manufactured by Pratt and Whitney's Canadian subsidiary. The engine first entered service in 1984.

Design

Originally called the PT7, the PW100 uses a relatively unusual three-shaft engine configuration. In the PW100, a centrifugal LP impeller (except for the PW150 which uses a 3-stage axial LP compressor), driven by a single stage LP turbine, supercharges a centrifugal HP impeller, driven by a single stage HP turbine. Power is delivered to the offset propeller reduction gearbox via a third shaft, connected to a 2-stage free (power) turbine.
