Sikorsky X-wing
The Sikorsky X-wing was an experimental hybrid helicopter/fixed-wing aircraft developed between 1983 and 1988 by helicopter manufacuter Sikorsky with NASA and DARPA funding.Intended to take off vertically like a helicopter, the craft's rigid rotors could be stopped in mid-flight to act as X-shaped wings to provide additional lift during forward flight, as well as having more conventional wings.
The X-wing may have been named after the fictional X-wing starfighter from the Star Wars movies.
