Definitions

  • the innovation relates to a warhead according to the preamble of claim 1.
  • Such a warhead is known from DE-OS 224 2930.
  • a warhead of this type is transported in large numbers by a missile or projectile over a target area and is ejected there, in order to then either fall down or braked down onto the target area.
  • the known warhead comprises a warhead housing in which a shaped charge is arranged and an igniter connected to the warhead housing.
  • an additional splinter-forming effect is also sought, which can be achieved by appropriate pre-fragmentation of the warhead housing. This pre-fragmentation, on the one hand, weakens the casing shell and, on the other hand, requires work steps that make the warhead more expensive, particularly in the case of casing shells made of high-quality steel.
  • the innovation is an object / specify an improved in terms of fragmentation warhead, which is cheaper to produce.
  • FIG. 1 shows a longitudinal section through a warhead 10, which includes a warhead housing 11 and a detonator 12 connected to it, with the omission of the innovation of insignificant parts.
  • the starting material for the warhead housing 11 is a circular blank 20 (circular metal piece), which is shown schematically in FIG.
  • the cup-shaped warhead housing 11 is preferably produced from the blank 20 by a shaping process such as deep drawing.
  • a wire mesh 21 is arranged on the round blank 20 before the deep-drawing process and rolled into the surface of the round blank 20.
  • the round blank 20 is then subjected to the forming process, so that the warhead housing 11 shown in FIG. 1 is produced.
  • the wire mesh 21 is arranged lying within the cup-shaped warhead housing 11.
  • the rolled-in and with formed wire mesh 21 favors the desired splitting effect when the warhead 10 is activated.
  • FIGS. 3, 4 and 5 show a highly schematic longitudinal section of the warhead 10, while FIG. 4 shows a cross section through the warhead housing along the line 4 - 4 of Figure 3.
  • FIG. 5 again shows a round blank as the starting product for the manufacture of the warhead housing of the warhead 10 according to FIG. 3.
  • the warhead housing 11 of the warhead 10 according to FIG. 3 consists of a multilayer structure and in particular comprises two layers 11 a, 11 b, which enclose a wire mesh 21 between them.
  • This warhead is expediently produced from a round blank 50 (FIG. 5), which consists of two metal layers 51 a, 51 b lying one above the other, which enclose a wire mesh 21 between them.
  • This circular blank 50 is produced, for example, by first placing the wire mesh 21 on the first metal layer 51 a and covering it with the second metal layer 51. This layer structure is then connected to one another by rolling.
  • the warhead housing 11 is produced again from the round blank 50 by a reshaping process.
  • the wire mesh 21 lying between the layers 11 a, 11 b of the warhead 11 in turn promotes the formation of fragments.
  • the wire mesh 21 can be made of the same metal, for example steel, as the warhead housing 11 itself. A particularly favorable splintering is achieved, however, if the wire mesh 21 consists of a wire mesh that has different mechanical and / or thermal properties as the material of the warhead housing 11 has. If, for example, the warhead housing 11 is made of steel, the wire mesh 21 can expediently be made of tungsten wire.
