Sikorsky, the longtime manufacturer of rotorcraft such as the UH-60 Blackhawk and S-92 helicopter, is exploring a new family of vertical takeoff and landing (VTOL) aircraft.
The Lockheed Martin-owned firm on Tuesday unveiled its plan to build, test, and fly a fully autonomous, hybrid-electric VTOL demonstrator called HEX, which it said will be the first in a series of large, self-flying VTOL models.
