Pratt & Whitney Canada Corp. is a global aerospace company specializing in the design, development, and manufacture of aircraft engines for small and medium aircraft. Founded in November 1928 as The Canadian Pratt & Whitney Aircraft Company, Ltd., the company evolved over subsequent decades into Pratt & Whitney Canada, operating as a subsidiary within the Pratt & Whitney business segment of RTX Corporation. Headquartered in Longueuil, Quebec, Pratt & Whitney Canada develops turboprop, turboshaft, and turbofan engines used in business, regional, and general aviation aircraft, as well as helicopters engines.
Pratt & Whitney Canada is developing a hybrid-electric propulsion system under the RTX Hybrid-Electric Flight Demonstrator program, designed for use on regional turboprop aircraft, with a modified De Havilland Canada Dash 8-100 serving as the test platform and first flight targeted for 2027. The system combines a thermal engine with a 1-megawatt electric motor from Collins Aerospace and a battery pack from Swiss firm H55, aiming to deliver up to 30% better fuel efficiency compared to today’s regional turboprops.
As part of the program, the company also developed a first-of-its-kind bidirectional charging system capable of 1,500 volts and 280 kW, built in collaboration with Canada’s National Research Council since no commercial charger of that scale previously existed. The project is backed by more than $163 million CAD in support from the Canadian federal and Quebec governments, underscoring its role in advancing sustainable aviation. Pratt & Whitney Canada has extended this leadership internationally as well, leading the European Union’s PHARES project under Clean Aviation alongside partners including Airbus and ATR.
