History

The Canadian Pratt & Whitney Aircraft Company, Ltd. was founded in November 1928 to act as a service centre for P&W aircraft engines. During

Pratt & Whitney Wasp The Pratt & Whitney Wasp was the civilian name of a family of air-cooled, radial piston engines developed in the 1920s, 1930s, and 1940s. The Pratt & Whitney Aircraft Company (P&W) was founded in 1925 by Frederick B. Rentschler, who had previ ...

series engines built in the U.S. In 1952, the production of Wasp engines was transferred to Canadian Pratt & Whitney so P&W could concentrate on developing jet engines. In the late 1950s, a team of 12 Canadian Pratt & Whitney engineers began the development of the first small turbine engine in Canada, the PT6. The first example was delivered to a customer in 1963. In 1962, the company was renamed United Aircraft of Canada (UAC), and assumed its current name in 1975. In 1963 a total of 41 Sikorsky CH-124 Sea King (originally CHSS-2)

Next Generation Regional Turboprop

By 2017, PWC was developing a new engine, the ''Next Generation Regional Turboprop'', scalable from for 90-seaters and featuring a new compressor, state-of-the-art propeller and nacelle among technologies, materials and manufacturing processes improvements to deliver 20% better

and 20% less maintenance costs than the PW100. The high-efficiency compressor testing began in 2012 and ran the full range of aerodynamic design points to validate the component efficiency and pressure ratio. Compressor tests were successfully completed in 2016 and Hot-section technology was to be adapted from the PW1000G. PWC targeted 2023-25 for its introduction, and it was to halve operating cost per shaft horsepower.
