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.
"Performing end-to-end tests of our pioneering hybrid-electric propulsion system and batteries marks another critical milestone toward our goal of demonstrating this promising technology in flight," said Jean Thomassin, executive director, new products and services introduction, Pratt & Whitney Canada. "Ultimately, we are targeting up to 30% improved fuel efficiency compared to today's regional turboprops, and insights from this project are also helping us advance the development of hybrid-electric technology to address multiple future platforms."
