Folding wing for a missile and a missile that has at least one folding wing in its configuration

摘要

A folding wing (2) for a missile, which comprises: - an alar socket (6); - an upper part of the wing (4) held in folding form in the alar socket (6) around a rotating shaft (10), with the upper part of the wing (4) presenting a first hinge component (12) with at least a first hinge bushing (14), and with said alar insert (6) comprising a second hinge component (16) with at least a second hinge bushing; - at least one element of elastically prestressed force; and - a coupling device having means adapted to the shape (30, 32, 35, 34) that correspond to each other, where at least a first element of elastically prestressed force (42) is coupled with the alar insert (6) and the upper part of the wing (4), and is designed to permanently propel the upper part of the wing (4) towards a working position related to the alar insert (6) through the introduction of a torque, where the device Hitch is designed to brake the upper part of the wing (4) before it automatically reaches the working position, where an axle element (44) extends through the axle openings (22, 40) of the first hinge bushing (14) and the second hinge bushing (18) to define the rotating shaft (10), where the first hinge bushing (14) and the second hinge bushing (18) are adapted to slide along one of the other at least outside the working position, where the first bisagr bushing a (14) comprises a base (20), the first means adapted to the shape (30, 32) at a distance from the rotating shaft (10) and facing the alar insert (6) whose shape corresponds to the second adapted means to the form (35, 54), wherein said first means adapted to the form (30, 32) are in the form of a first projection (30) and a second projection (32) which further extends from the base (20 ) in comparison to the first (30), with both projections (30, 32) located at opposite edges of the base (20) of the first hinge bushing (14). where the second means adapted to the shape (35, 54) are in the form of a first upper resting surface (35) in the second hinge bushing (18) and a second resting surface (54) in the alar socket (6); and where the first and second means adapted to the shape (30, 32, 35 and 54) are configured relative to each other such that the first (30, 32) are located directly before and engage with the second (35, 54 ) in the work position.
