Two STOPPED-ROTOR FLIGHT SYSTEMS that would add supersonic speed capabilities to conventional rotor-winged aircraft concepts, have been proposed by a Ryan Aeronautical Company engineer. Peter F. Girard, head of advanced programs for the San Diego firm and former chief engineering test pilot for Ryan, introduced the two concepts before the Dayton, Ohio, Section of the American Helicopter Society October 5.

Each of the systems represents a distinctly different concept. One, known as the "Vertiwing," employs a delta-shaped, rotating wing that provides vertical lift characteristics plus fixed-wing capabilities. Once airborne, the aircraft's delta wing rotation is stopped and conventional, fixed-wing configuration is assumed, permitting high-speed performance.

The thin, highly swept double delta wing possesses very desirable supersonic characteristics and some variants, with high fineness ratio fuselages and special engine inlets, are capable of high supersonic speeds, yet able to hover at disc loading under 25 pounds per square foot.

Pete Girard's concept was initially called the Heliplane, and its very original rotor system the "Girawing" (which I guess was a play on the suffix "gyro-", indicating rotation, and Girard's own name).
I'm adding to this thread:
  • An article about Girard's Heliplane concept, showing an image of the so-called "Vertiwing Mark II" design;
  • A photo of Girard holding a model of the same design;
  • Two drawings of Girard's "Heliplane F-104" design;
  • Photos of three different kitbuilds of the same in hypothetical USAF and NASA liveries;
  • A photo of a crude Vertiwing RPV proposal;
  • A set of five photos and one painting of the Ryan Model 278 Vertiwing, a proof-of-concept vehicle that was considered at some point but not built (from the SDASM's Teledyne Ryan archives);
  • Two sheets of patent artwork from 1963 showing the Vertiwing Mark III.
