Pratt & Whitney Canada has begun ground testing of the flight-standard propulsion system and propeller for its RTX Hybrid-Electric Flight Demonstrator project in Quebec. This system combines a Pratt & Whitney Canada thermal engine with a 1-megawatt electric motor from Collins Aerospace and a battery system from H55 S.A.

Following ground tests, the hybrid-electric propulsion system will be installed on a De Havilland Canada Dash 8-100 experimental aircraft, with the first flight anticipated in 2027. The project aims to demonstrate up to 30% improved fuel efficiency for regional turboprop missions.

Jean Thomassin of Pratt & Whitney Canada stated the testing is a significant step toward proving hybrid-electric technology in flight, potentially enhancing fuel efficiency and performance across various future aircraft applications. The project involves collaboration with numerous industry partners and research institutions, supported by the governments of Canada and Quebec.
