RTX (RTX) unit Pratt & Whitney Canada launched a new phase in the RTX hybrid-electric flight demonstrator project, with testing of the propulsion system and propeller to be conducted in Quebec, the company said Tuesday.

After the ground test, the hybrid-electric propulsion system will be installed on the De Havilland Canada Dash 8-100 experimental aircraft, with an inaugural test flight expected in 2027, the company said.

The propulsion system combines an advanced Pratt & Whitney Canada thermal engine with a 1-megawatt electric motor developed by RTX's Collins Aerospace and a battery system by Switzerland's H55, the company said.
