Abstract

A fin of a missile or projectile which can be folded and unfolded in a space saving manner and which is composed of two fin blades which are connected to one another at their tips and are fastened at their roots to respective different bearings. One of the bearings is an articulated fixed bearing, while the second bearing is an articulated slide guide bearing which slides in a groove. This groove is oriented so that in the collapsed or folded state, the fixed bearing and the slide guide bearing are arranged one behind the other in the circumferential direction, and so that with increasing distance from the fixed bearing, the slide guide bearing will be at an ever greater distance from the center axis of the missile and cause the fin blades, in the unfolded state, to have a symmetrical configuration relative to the respective fin axis outside of the periphery of the missile.
