Pratt & Whitney hits major milestone in hybrid-electric propulsion development
Pratt & Whitney Canada has reached a major milestone in the development of its hybrid-electric propulsion system and will enter a new distinct phase in its research.
On July 21, 2026, RTX-owned Pratt & Whitney said after several years of development it would begin ground testing of the flight-standard propulsion system and propeller in Longueuil, Quebec.
Following completion of the ground test, the hybrid-electric propulsion system will be installed on a De Havilland Canada Dash 8-100 experimental aircraft, with the first flight expected in 2027.
The hybrid-electric propulsion system combines an advanced Pratt & Whitney Canada thermal engine with a one-megawatt electric motor and motor controller developed by RTX’s Collins Aerospace, along with a battery system supplied by H55.
With the electric motor providing additional power during demanding flight phases such as takeoff and climb, the hybrid-electric architecture enables the propulsion system to operate more efficiently throughout the flight mission.
RTXThe project aims to demonstrate up to 30% improved fuel efficiency for a typical 250-nautical-mile regional turboprop mission.
The RTX Hybrid-Electric Flight Demonstrator project has accelerated collaboration between leading aerospace industry companies and research institutions within Canada and abroad, including De Havilland Aircraft of Canada, GKN Aerospace, AeroTEC, Ricardo, the National Research Council of Canada and the Innovative Vehicle Institute.
The project is supported by the governments of Canada and Quebec. Additionally, the project’s propulsion system verification phase is supported by Strix, the organization managing Canada’s Initiative for Sustainable Aviation Technology (INSAT), with funding from the Government of Canada, as part of its fifth wave of innovative research projects.
