Pratt & Whitney Canada PW100
The Pratt & Whitney Canada PW100 aircraft engine family is a series of 1,800 to 5,000 shaft horsepower (1,300 to 3,700 kW) turboprops manufactured by Pratt & Whitney Canada. The engine first entered service in 1984. Pratt & Whitney Canada dominates the turboprops market with 89% of the turboprop regional airliner installed base in 2016, leading GE Aviation and Allison Engine Company.[1]

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 two-stage free (power) turbine.

- PW150 Twin Pack
- A proposed powerplant for the Airbus A400M Atlas;[4] two PW150-based engines would be used to drive a single propeller.[5] The powerplant was eliminated from contention by Airbus in early June 1999, since it narrowly missed providing the 9,000 shp (6,700 kW) required to drive the eight-bladed propeller at the time, and its specific fuel consumption (SFC) was slightly excessive.[6]
- PW150A
- Certified in 1998-06-24 with a maximum continuous rating of 5071 SHP (3782 kW),[3] although capable of up to 7000 SHP. Has a 3 stage axial low pressure compressor instead of the centrifugal NL unit on other variants. Used on the Bombardier Q400 and Antonov An-132.
