P&W, Collins Team on Hybrid-Electric AAM Demonstrator
P&W and Collins are developing a hybrid-electric technology demonstrator for advanced air mobility vehicles.

Raytheon Technologies subsidiaries Pratt & Whitney (P&W) and Collins Aerospace unveiled at the Farnborough International Airshow this week a new hybrid-electric technology demonstrator program for future advanced air mobility (AAM) vehicles. The Scalable Turboelectric Powertrain Technology (STEP-Tech) demonstrator will focus on developing high-voltage distributed hybrid-electric propulsion concepts in the 100- to 500-kW class, with the potential to scale to 1-MW and beyond. The modular demonstrator platform enables rapid prototyping of a wide range of configurations, the companies said, and plans call for ground testing to begin late this year.
