The aircraft (20,50,60) combines a low aspect ratio lifting body (21) and a higher aspect ratio wing (30). Horizontal and vertical tail surfaces (26, 24) are connected to the rear of the lifting body (21) by one or more booms (23). The wing (30) is attached to the lifting body (21) such that it can be rotated about a spanwise axis (39) and it's aerodynamic center is located behind the aerodynamic center of the lifting body (21). The wing (30) contains adjustable surfaces (31, 32) to change the wing's camber for lift and roll control. A lever arrangement (FIG. 7) controlled by the pilot or remote control operator selectively and relatively pivots the wing (30) and contours the wing surfaces for camber to optimize the lift and control of the lifting body (21) and the wing (30) for maximum efficiency in all flight modes.

[ What is claimed is:] [1.]1. An aircraft having a center of gravity and comprising:a lifting body having an aspect ratio less than two, a payload compartment and an aerodynamic center;a rotatable wing with an aspect ratio greater than three, said wing being rotatably connected to the lifting body rearwardly of the aircraft center of gravity, said wing having a wing aerodynamic center and being rotatable about a spanwise axis that is relatively near the wing aerodynamic center;said wing being rotatable in pitch relative to the lifting body;said wing including spanwise aerodynamic surfaces hinged to move automatically as the wing is rotated such that the wing camber is increased and decreased automatically proportionally as the wing is rotated relative to the lifting body; andwherein rotation of the wing to decrease its angle of attack relative to the lifting body increases the angle of attack of the lifting body, and rotation of the wing to increase its angle of attack relative to the lifting body decreases the angle of attack of the lifting body.
