Hi.
On 06/09/2011, a team of 6 engineers from China's AVIC Chengdu Aircraft Research Institute filled a patent for an advanced supersonic weapon system of interest described as "a canard tailless aerodynamic configuration"
Abstract translates roughly as : "The utility model belongs to the technical field of the design of unmanned aerial vehicles, and relates to variant canard tailless aerodynamic configuration, which can realize flight with a high subsonic lift-to-drag ratio and a high supersonic lift-to-drag ratio simultaneously. Canards are arranged at the front of an airplane body, and can be folded and unfolded, wings are arranged on the rear of the airplane body, wing tips of the wings can deflect vertically, an air inlet channel is disposed at the front of the upper surface of the airplane body, a tail nozzle is arranged at the tail of the airplane body, and control surfaces are arranged on the rear edge of the airplane body and the rear edges of the wings. The variant canard tailless aerodynamic configuration adopts the design, the left and the right of the variant canard tailless aerodynamic configuration are symmetric, requirements of cruise at a high subsonic lift-to-drag ratio and supersonic penetration on aerodynamic force are efficiently met by the aid of the variation technology that the foldable wing tips and the foldable canards are combined, and contradiction of subsonic stealth cruise and supersonic flight heading stability on aerodynamic configuration is coordinately solved. The variant canard tailless aerodynamic configuration can be applied to the aerodynamic configuration design for various unmanned supersonic aircrafts."
