Raytheon Technologies' Pratt & Whitney and Collins Aerospace units have made significant progress on advancing hybrid-electric propulsion through the Scalable Turboelectric Powertrain Technology (STEP-Tech) demonstrator, which has completed its first engine run and electrical system integration test.

As a modular and scalable demonstrator platform, STEP-Tech provides for rapid prototyping of distributed propulsion concepts applicable to a range of next-generation applications, including advanced air mobility vehicles, high-speed eVTOL aircraft, and blended wing body aircraft, Raytheon said.
