A foldable missile wing is deployed by means of an overcenter linkage powered by a torsion spring assembly capable of exerting a generally linear bias on the linkage over its full range of motion. A separate lock linkage maintains the foldable wing in a deployed position until release actuation of the lock linkage occurs thereby enabling wing deployment.

A foldable wing deployment system comprising: a fixed wing section; a foldable wing section hinged to the fixed wing section; an overcenter linkage connecting the fixed and foldable wing sections for securely deploying the foldable wing section to a coextensive position with the fixed wing section; a first torsion bar having a first end connected to a first gear; a hollowed cylindrical torsion member mounted over the torsion bar, a first end of the member being fixed and a second end being connected to a corresponding second end of the torsion bar; a second torsion bar located in parallel proximity to the cylindrical torsion member and connected to the overcenter linkage; and a second gear mounted on the second torsion bar and contacting the first gear for exerting supplementary bias on the overcenter linkage during initial operation thereof for ensuring a substantially linear actuating drive on the linkage, necessary for smooth and reliable wing deployment.
