Abstract

The point portion (15) of a reduced calibre projectile (10) has a discontinuous contour in the form of a circular groove (20). Thereby, a boundary layer is determined between a supersonic speed flow range and a subsonic speed flow range; thereby it is possible to eliminate perturbations due to the flow during the separation of the sabot segments, not shown, of the projectile (10).
