Abstract

A wing structure for an aircraft designed for both STOL and supersonic flight conditions includes a biplanar wing arrangement in which the lower wing section is staggered behind the upper wing section and the lower wing section is designed for both translational and rotational displacements relative to the upper wing section. For short takeoff and landing capabilities, the lower wing section is rotated and translated relative to the upper wing section so that the leading edge of the lower wing section is adjacent to the trailing edge of the upper wing section. For high speed supersonic flight, the lower wing section is adjacent to the trailing edge of the upper wing section. For high speed supersonic flight, the lower wing section is rotated and translated relative to the upper wing section so that the wing sections are substantially parallel.
