Fin unit for a projectile, in particular for a supersonic sub-calibre projectile

摘要

The assembly consists of three or more fins (8) which are implanted in a support (9), to which they are joined by connecting feet (7a). In addition, each fin has an aperture (3) in it which is bounded on one side by the support; the height (H) of the aperture is determined so as to reduce the Magnus force resulting from the air flow over the body of the missile. The fixing feet on the fins are fitted into cavities in the body of the missile and fixed in place e.g. by welding or adhesive. The support is attached to the rear of the missile body e.g. by a threaded surface (10). <IMAGE>
