A method for the application of rotating bands on a projectile body comprises winding at least one layer of a first ribbon-like material around the projectile body; fastening the ribbon-like material on the projectile body by applying a laser or electron beam in a deep-penetration welding process; and giving the beam an intensity so that only a small zone near the surface of the projectile body is melted to the ribbon-like material.

Method for the application and fastening of rotating bands on projectile

A guide assembly for a missile or projectile which has a plurality of space saving, foldable fins, with each such fin being composed of two fin blades that are connected together at their tips and whose root ends are fastened in different bearings. To prevent bending or bulging of the fin blades in the unfolded state of the fins, at least one bending prevention arrangement is disposed between the fin blades in the vicinity of their root ends.

Guide assembly having unfoldable fins for projectiles and missiles

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.
