Abstract: A simple, retractable, self-erecting wing for a low speed missile having a fabric wing cover affixed to a leading edge structure that is the only erected structural member in the wing operative position. The wing cover forms a pocket that contains air. The leading edge structure is hinged and folds, along with the wing cover, into a compact slotted space adjacent the outer wall of a missile body. In the folded position the leading edge structure forms a cover for the slot and the cover coincides with the outer shape of the missile body. A large fabric wing can be completely stored within the missile body for minimum drag during any high speed portion of the missile flight, the wing being released to the operative position by a simple mechanism.

Abstract: An articulated nose is locked in axial alignment with the longitudinal axis of a rolling projectile body. Pyrotechnic means within the nose is actuated to unlock the nose and tilt it toward the target when the error between the projectile path and the path to the target exceeds a predetermined threshold.

Abstract: A sealing liner of flexible material such as Teflon has a downwardly tapering side wall which is positioned over a header. A case is positioned over the liner, and the top of the case is moved into engagement with the top of the liner to capture the tapered side wall of the liner between the side walls of the header and the case to provide a tight cold flow seal so that small particles working loose from the case cannot reach the header.

Abstract: A method of electroforming a part comprising the steps of electroless depositing a coat of metal on a mandrel of heat shrinkable material, electrodepositing a second coating of metal over the first coat, heating to a temperature which will shrink the mandrel, and removing the shrunken mandrel from the electroformed part.
