ABSTRACT:
Provided is an aerodynamic body having rhomboid wings and internal torsion bars which can be twisted to affect a change in the shape of a wing. Individual or multiple swings can slide relative to the fuselage body to affect a change in sweep angle and aspect ratio. Provided is a method of controlling the aerodynamic properties, in order to affect stability and maneuvering, of an aerodynamic body by warping the wings by twisting one or more torsion bars located internal to one or more wings. Additional control can be exercized by sliding one of more wings relative to the fuselage to change the sweep angle and aspect ratio.
