CORRECTION: Pratt & Whitney Canada Achieves Full-Power Test Of Hybrid-Electric Propulsion System For Dash 8-100 Experimental Aircraft

Future flight-testing targets 30% improved fuel efficiency for regional turboprops

PARIS, June 16, 2025 /PRNewswire/ -- Pratt & Whitney Canada announces a new milestone in the RTX Hybrid-Electric Flight Demonstrator project, by testing the integrated propulsion system and batteries to full power. While ground testing of the hybrid-electric propulsion system continues in Longueuil, Quebec, Pratt & Whitney Canada has selected AeroTEC to support future flight testing of the De Havilland Canada Dash 8-100 experimental aircraft. Pratt & Whitney is an RTX (NYSE:RTX) business.

The new end-to-end test marks the first battery-powered operation of the propulsion system, which combines a highly efficient Pratt & Whitney Canada thermal engine with a 1 megawatt (MW) electric motor developed by RTX business, Collins Aerospace. The 200 kilowatt-hour (kWh) batteries, supplied by H55 S.A., have also been successfully charged and discharged using the high-voltage Mobile Charging Unit co-developed by Pratt & Whitney Canada, the National Research Council of Canada and the Innovative Vehicle Institute. H55 is supported by RTX Ventures, the venture capital arm of RTX.
