The device of the invention provides for the substantially constant unfolding of unfoldable fins on a guided missile without damaging the bearing structure or the fin itself. The device comprises a deformation part placed around a bearing neck that is joined to the fin. Means are used to convert the rotational kinetic energy due to the unfolding of the fin into translational energy. These means comprise, in particular, a compression ring which is displaced and compresses the deformation part in conjunction with the rotation of the bearing neck due to the unfolding of the fin. The invention can be used in missiles, self-propelled rockets and similar devices.

A guided missile, which comprises; a body; at least one pair of unfolding fins mounted on said body; and a device for braking unfolding of said fins wherein said device comprises a device to brake the unfolding of said at least one pair of unfolding fins with respect to a body, said device being hinged on a bearing neck which is fixed with respect to said body, wherein said bearing neck is rotatable about an axis of said body so as to unfold said fins by rotation of said bearing neck about said axis, said device comprising: a stop element positioned on said body; and means for converting rotational kinetic energy into translational energy, wherein said converting means comprises: a screw thread formed on an outer surface of said bearing neck; a compression ring screwed onto said screw thread; and a deformation part positioned around said bearing neck between said stop element positioned on said body and said compression ring such that said fins unfold at a substantially constant velocity and said converting means absorbs part of the rotational kinetic energy of said fins upon unfolding.
