Lockheed Martin Corporation subsidiary Sikorsky Aircraft Corporation tested a new full-authority, fly-by-wire flight control technology kit for the first time on a Sikorsky UH-60 Black Hawk medium-lift utility helicopter. The flight marked the beginning of the flight test program for the soon-to-be optionally piloted rotorcraft.
Th flight was conducted at Sikorsky’s West Palm Beach, Florida facility. Sikorsky will continue to expand the flight test envelope throughout the summer and achieve fully autonomous flight capability for Blackhawk helicopters in 2020.
The technology kit, referred to as optionally-piloted vehicle (OPV) technology, is an evolution of the company’s previous fly-by-wire technology. It is the first full authority fly-by-wire retrofit kit that involves completely removal of mechanical flight controls from the aircraft. Ultimately, it is designed to reduce the number one cause of helicopter crashes: Controlled Flight Into Terrain (CFIT).
