ABSTRACT:
Fore mounted aft swept and aft mounted forward swept wings extend from either side of a lifting body fuselage. Each lateral pair of the wings is joined at the tops by a wing tip vortex translating device to induce translation of the tip generated vortices along the trailing edge of the aft wings. End plates extend rearwardly from the maximum chord thickness of the fuselage to increase the effective lift of the fuselage. An elevator, mounted intermediate the rear top of the end plates, provides pitch control and structurally augments the wing root and fuselage junction of the aft mounted wings. A power plant disposed at the rear of the fuselage provides thrust and also dissipates, as useful thrust, the wing tip vortices translated from the tips to the power plant along the trailing edges of the aft wings.
