Definitions

  • the invention relates to a fragmentary projectile as defined by the preamble of claim 1.
  • Such fragments are known for example from US 3,000,309.
  • the side of the inner shell facing the explosive is designed in such a way that the explosion gases can attack locally or local hollow charge effects can be exploited.
  • a splinter floor is shown in Fig. 2, which also consists of several shell casings. In this case, however, the splinter shell and the zirconium shell causing the fire are separate units.
  • a disadvantage of this invention is the fact that a large number of undefined fragments arise. There is no reproducible splinter distribution.
  • the object of the present invention is, based on US 3,000,309, to further develop a splinter projectile in such a way that the actual splinter casing is particularly easy to manufacture, and in addition that a desired fire effect, e.g. B. when fighting aircraft tanks.
  • the invention is therefore based on the idea of generating an optimization of the splintering and fire effect in that the structural zones of the inner shell consist of areas of smaller wall thickness than the parts of the shell surrounding the structural zones.
  • the wall thicknesses, casing materials and the number of casings determine the shape and mass distribution of the splinters and - depending on the intended use - can be optimally adapted to the target requirements.
  • the fragmentary floor consisting of several shell casings is designated by 1.
  • the shell is composed of the outer shell 2 and 3 and the inner shell 4.
  • Structural zones 7 are located in the inner shell 4 on the side facing away from the explosive 5. These structural zones 7 are selected such that the remaining wall thickness of the shell 4 at these points is less than the wall thickness of the parts of the shell 4 surrounding the structural zones.
  • FIG. 4 shows a top view
  • FIG. 4a shows a cross section of the inner shell 4 'with a structure zone distribution which is selected such that the parts of the shell 4' surrounding the structure zones have an approximately rectangular shape
  • FIG. 5 shows the top view of a projectile casing 4 ′′ with structural zones 7 ′′ which have a sawtooth shape (see FIG. 5a).
  • FIG. 6 shows the inner shell 4, the structural zones 7 and the adjacent outer shell 3.
  • the resulting shock wave pulse is coupled locally into the casing 3 at the contact points 8.
  • the energy coupled in at the contact points 8 accelerates partial regions of the outer shell 3 or induces voltage gradients in this shell. This leads to the formation of splinters whose geometry corresponds to the pattern made on the inner shell.
  • the shape, size and number of fragments and the speed of the splinters can be adjusted by suitable structuring of the inner shell 4.
