After testing himself the X-13 Vertijet Ryan, test pilot Peter Girard came to his own idea of a vertical take-off and landing (VTOL) jet fighter. The Girard’s concept was based on a sort of triangular shaped rotor/wing with movable tips. The wing rotated to take off like an helicopter and when the appropriate speed was achieve it became fixed to allow high-speed flight. To counteract the rotor torque he planned to employ compressed air outlets in the tail section.
In 1962 Lockheed and Ryan found some merit in the idea and in what’s better than Lockheed’s already stunning “Zip”? Sadly, it didn’t go any further.
In this photo a lovely done interpretation. It could have been this cool.
