Definitions

  • the invention relates to ammunition with a profiled explosive charge according to the preamble of claim 1.
  • the invention is based on DE 30 16 861 A1. This concerns ammunition with a shell for splintering.
  • the cylindrical one arranged in a splinter shell Explosive charge has axially parallel grooves of roof-shaped on the outer circumference Cross section on. The grooves, which are only filled with air, are effective when detonated the explosive charge as cutting charges, so that rod fragments from the shell be formed.
  • Splinters of approximately square cross-section are thereby according to US 3,491,694 formed that a cylindrical explosive charge on its outer circumference axially parallel, has roof-shaped, hollow grooves. These are mutually alternating staggered and when casting the explosive charge by a corresponding pre-shaped, heat-resistant film shaped. Upon detonation of the Explosives are related by the grooves corresponding cutting charge effects on the lying fragmentation shell. the energy transfer to the splitter (v o) through the film is greatly reduced between the grooves. Laboring the Foil in the mold is difficult and therefore hardly reproducible.
  • the object of the invention is to produce reproducible fragments with a high breakdown capacity generate, the explosive device, consisting of the fragment shell and the Explosive charge, should be inexpensive and easy to manufacture.
  • the explosive charge is a profiled surface pattern has, the splinters are clearly determined geometrically, namely through merging hollow groove in accordance with the intended, shell-side Splitter number.
  • the splinters can be produced in any shape and size.
  • the Splinter shape can be polygonal, rectangular, square, circular, elliptical.
  • the dimensions of the splinters are to be provided so that an optimal pressure build-up on the explosive side of the fragments.
  • the pressure distribution behind the Splintering corresponds to the initial condition when the explosive is detonated v 0 ⁇ 0 (2000 m / s).
  • the splinter cover is smooth on both sides and can be machined or cut without cutting and is therefore inexpensive to manufacture.
  • the explosive charge has the surface pattern formed by grooves on its circumference. The grooves are also inexpensive to machine or non-cutting. Due to the gap-free and non-slip arrangement of the explosive charge on the shell, there are no pressure losses, so that the splinters generated from the shell receive optimum energy.
  • ammunition 1 for example a warhead, one Gun ammunition, a hand grenade, essentially from a fragment-forming Shell 2 and from a cylindrical explosive charge 4 with a circumferential, geometric surface pattern 6 with surfaces 12.
  • the surfaces 12 are through circumferential and axially parallel grooves 8, 9 with a roof-shaped cross section 10 formed.
  • Both the circumferential and the axially parallel grooves 8, 9 have the same Cross section 10.
  • the grooves 8, 9 can also have different cross sections Own 10.
  • the explosive charge 4 sits in the shell 2 without a gap.
  • An adhesive 7 secures the explosive charge 4th
  • the grooves 8, 9, 22-24 cause cutting charge effects 5 with respect to the shell 2, so that according to the surface pattern 6, 16-19 from the shell 2 fast and depending on the size heavy splinters are generated.
  • the grooves 8, 10 arranged on the cylindrical explosive charge 4 can be in in the same way on oval, spherical or pointed arch-shaped explosive charges 4 or explosive charge sections.
  • Staggered square surfaces 12 on the explosive charge 4 with grooves 8, 9 corresponding to a surface pattern 16 are shown in Figure 2.
  • Hexagonal surfaces 13 on the explosive charge 4 are appealing according to FIG a surface pattern 17 delimited by grooves 22.
  • Circular and elliptical surfaces 14, 15 on explosive charges 4 are in accordance with the surface pattern 18,19 delimited by grooves 23, 24.
  • On the shell 2 by blasting projected gussets 30, 31 are particularly effective as pointed splinters.
  • An increase in performance can be achieved by lining the grooves with metal, such as copper, reachable.
  • metal such as copper
  • a smaller groove depth and the mechanical one are advantageously required Strength, especially the bullet resistance of the explosive charge 4 optimized.
  • the explosive charge can Surface patterns can be arranged in the form of a multi-start spiral.
