Yesterday, Sikorsky revealed plans to build, test and fly a large-scale hybrid-electric vertical takeoff and landing (VTOL) tilt-wing demonstrator. Dubbed HEX (for “hybrid-electric”), the project is expected to be the first of a series of large, next-gen VTOLs featuring varying degrees of electrification and advanced autonomy technology “for optionally-piloted flight,” Sikorsky said in a statement.
