. United Technologies has given PWC a world mandate for small and medium aircraft engines while P&W's US operations develop and manufacture larger engines. Although PWC is a division of P&W, it does its own research, development and marketing as well as the manufacturing of its engines. The company currently has about 10,000 employees worldwide, with 6,000 of them in Canada.

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 World War II, it assembled Pratt & Whitney Wasp 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

Next Generation Regional Turboprop

PWC is 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 fuel efficiency 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 will be adapted from the PW1000G. PWC targets 2023-25 for its introduction, and it should halve operating cost per shaft horsepower.
