Abstract

A procedure for producing a warhead with controlled fragmentation includes manufacturing an inner shell and filling it with an explosive substance. The procedure further includes providing a net around the outer surface of the inner shell as well as depositing a material on and around the net. A warhead is produced by the procedure and includes an inner shell. A material applied to the warhead comprises weak points for guided fragmentation of the deposited material upon detonation of the warhead.

Claims (25)

1. A procedure for producing a warhead with controlled fragmentation, the procedure comprising:

manufacturing an inner shell and filling the inner shell with an explosive substance;

providing a net around an outer surface of the inner shell;

applying a material in powder form or in thread form with an additive method of manufacture on and around the net;

manufacturing a plurality of preformed projectiles;

arraying the preformed projectiles along the outer surface of the inner shell, inside the net, so that the preformed projectiles are retained in respective positions of the preformed projectiles; and

applying the material in powder form or in thread form on and around the preformed projectiles simultaneously with affixing the material in powder form on and around the net.

2. A warhead produced by a procedure according to claim 1 , the warhead including the inner shell, and the material in powder form applied to the warhead comprises weak points for a guided fragmentation of the material in powder form applied to the warhead upon detonation of the warhead.

3. A warhead according to claim 2 , wherein the weak points in the material in powder form applied to the warhead are arranged in positions corresponding to a position of the net.

4. A warhead according to claim 2 , wherein the weak points in the material in powder form applied to the warhead are arranged in other positions that are selected by deposition of the material.

5. A warhead according to claim 2 , comprising a plurality of preformed fragments provided inside the material in powder form applied to the warhead.

6. A procedure for producing a warhead with controlled fragmentation, the procedure comprising:

manufacturing an inner shell and filling the inner shell with an explosive substance;

providing a net around an outer surface of the inner shell;

applying a material in powder form or in thread form with an additive method of manufacture on and around the net; and

applying the material in powder form with varying speed so that weak points are produced in the material in powder form.

7. A procedure for producing a warhead with controlled fragmentation, the procedure comprising:

manufacturing an inner shell and filling the inner shell with an explosive substance;

providing a net around an outer surface of the inner shell;

applying a material in powder form or in thread form with an additive method of manufacture on and around the net; and

applying the material in powder form with varying temperature so that weak points are produced in the material in powder form.

8. A procedure for producing a warhead with controlled fragmentation, the procedure comprising:

manufacturing an inner shell and filling the inner shell with an explosive substance;

providing a net around an outer surface of the inner shell;

applying a material in thread form with an additive method of manufacture on and around the net.
