Abstract
A folding wing structure for improved missile aerodynamic performance and manuverability with a minimum payload space requirement which comprises a leading edge spar and at least one trailing edge spar spaced apart from each other by a plurality of transverse ribs, the spars being approximately parallel to each other with the ribs positioned along the spars to divide the structure into a series of parallelograms. The spars and ribs are pivotally joined together with the spars being further pivotally joined to an air frame of an aerodynamic vehicle or missile. In a folded position the spars and rib structure collapse to occupy a minimal amount of volume in a recessed area of the air frame. A spring or piston member secured to at least one, spar forces the spars apart and out from the fuselage to an erected wing position at predetermined sweep angles relative to the fuselage.
