  • Patent number: 5204493
    Abstract: This task is solved according to the invention by a design corresponding to the characteristic of the claim. The inert insertion according to the invention has the shape of a cylinder with a cone or truncated cone-shaped extension whereby the transition from cylinder to extension takes place without break. The inert insertion is to be arranged in the explosive of the shaped charge oriented such that it points with its free end tapering to the cone tip or top surface, respectively, of the truncated cone in the direction to the primer charge and correspondingly with its cylindrical part in the direction to the lining of the shaped charge. This inert insertion from cylinder and cone or truncated cone, respectively, has been shown to be especially favorable in comparison to the well-known forms of inert insertion. The effect of shaped charge rounds equipped with it on modern multiplate targets was significantly better than those of charges with inert insertions of conventional form.
