SWITCH Hybrid-electric Propulsion Project

under testing

The SWITCH project is focused on demonstrating hybrid-electric propulsion technology on a full-scale Pratt & Whitney Geared Turbofan engine. Testing of the electric motor drive systems, including motor generators, controllers, and power distribution systems, is being conducted at Collins Aerospace’s advanced electric power systems lab, The Grid, in Rockford, Illinois. The project involves integration of megawatt-class motor generators with a GTF engine demonstrator for future single-aisle airliners.
