Double fabric retractable wing construction

In a missile having an elongated body, the body having an outer wall with a plurality of circumferentially spaced, longitudinally extended slots therein, a retractable self-erecting wing mounted in each slot, each wing comprising:

• a single extendable strut member at the leading edge of the wing pivotally mounted in the body at the forward end of the slot and biased to swing outwardly from the body, said strut member including strut sections pivotally connected by pivot means for folding said strut member and said wing cover to the wing stored position and for extending said wing to the operative position;
• means on said strut sections for urging said strut sections to the extended position;
• a flexible wing cover affixed to said strut member for forming a wing with an internal air pocket in the extended position, said wing cover being movable with said strut member;
• means at the bottom of said wing cover to secure the wing cover to the missile body;
• retaining means for holding the wing cover in the stored position with said strut member and folded wing cover folded within the slot, said retaining means comprising a substantially U-shaped rod connected to the missile body and the bottom portion of said wing cover, with the legs of said U-shaped member sufficiently spaced apart to pass the folded wing cover and folded strut member therebetween;
• and
• extension means operatively mounted on the body for extending said wing.
