A device for the production of explosive formed projectiles includes a cag with an explosive filling, an ignition device arranged at the bottom and a disc-shaped metal insert covering the top of the explosive filling. In order to produce several projectiles or a single projectile composed of several such projectiles with a large l/d ratio, the insert includes at least two discs, arranged directly behind each other.

Producing explosive-formed projectiles

A warhead including a shell which encloses the explosive charge and a projectile forming liner with the liner being disposed so that its circumferential surface lies against an intermediate ring which, in turn, is fastened to the shell. To avoid undefinable spalling effects in the region of the boundary surfaces between the liner and the shell, which could result in asymmetrical tail formation for the projectile produced by the detonative resharping of the liner, the intermediate ring and the liner have the same acoustic impedance.

Warhead

An arrangement for production of explosively formed projectiles consists of casing with explosive contents, a fuse arranged on the base side and a metal insert which covers the explosive contents on the head side, in which case the projectile acquires wing-like symmetrical folds on its tail by means of the following. The insert and/or the explosive contents and/or the fuse in their outside area and/or the casing on its jacket features at least three inhomogeneities arranged at a distance from the axis of the casing in a symmetrical manner around the circumference such that in the circumferential area of the insert varied. Acceleration is achieved according to the configuration of the inhomogeneities or the impact time of the shock wave or its impact energy is different.
