The Pratt & Whitney Canada PW100 aircraft engine family is a series of 2,000 to 5,000 horsepower (1,500 to 3,700 kW) turboprops manufactured by Pratt & Whitney Canada. The engine first entered service in 1984. It dominates its market with 89% of the turboprop regional airliner installed base in 2016, leading GE Aviation and Allison Engines.
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.
