RTX STEP-Tech demonstrator completes first engine run

RTX (previously known as Raytheon Technologies, which now incorporates Collins Aerospace, Pratt & Whitney and Raytheon) has announced significant progress by Pratt & Whitney and Collins Aerospace on advancing hybrid-electric propulsion through the Scalable Turboelectric Powertrain Technology (STEP-Tech) demonstrator.  STEP-Tech is intended for rapid prototyping of distributed propulsion concepts, applicable to a wide range of next generation applications, such as advanced air mobility vehicles, high-speed eVTOL and blended wing body aircraft.  The first successful test was conducted at the Raytheon Technologies Research Centre in Connecticut. The test included the first run of STEP-Tech’s turbogenerator loaded at partial power. This was
