Collins Aerospace has produced a prototype of the solid-state power controller and distribution panel as part of its contribution to the European Union-backed SWITCH project to develop hybrid-electric propulsion technology for short- and medium-range airliners. The hardware was developed at the RTX group company’s facility in Nördlingen, Germany, and is now being shipped to The Grid electric power systems laboratory in Rockford, Illinois, where it will be integrated with a powertrain demonstrator.

SWITCH stands for Sustainable Water Injecting Turbofan Comprising Hybrid-Electrics, and the consortium behind the project encompasses RTX companies Pratt & Whitney and Collins Aerospace, as well as MTU Aero Engines, GKN Aerospace, and Airbus. The demonstrator combines a Pratt & Whitney Geared Turbofan engine with a pair of Collins’ two-megawatt electric motor generators mounted on the low and high spools of the engine.
