Definitions

  • the invention relates to an explosive projectile with a single or multi-layer outer shell according to the preamble of claim 1.
  • Such an explosive projectile is known from DE-OS 2 518 044.
  • the splinter bodies arranged in the multilayered outer shell also extend into the ogival front part of the projectile body, the splinter effect which can be achieved thereby is not yet satisfactory in the direction of flight.
  • the splinter bodies are accelerated predominantly in the radial direction, with the result that an optimal splinter effect cannot be achieved in a certain solid angle region immediately in front of the explosive projectile.
  • the detonator which is necessarily arranged in the tip of the explosive projectile and detonates the impact projectile upon impact and / or approach, prevents a more suitable splintering effect in this known solution.
  • the invention has for its object to significantly increase the splintering effect, in particular directly in the direction of flight of the explosive projectile, and at the same time to reduce the cost of producing such a projectile.
  • FIG. 1 shows an explosive projectile with a multilayer outer casing 19, 19 ', 19 ", in which at least one layer comprises preformed splinter bodies 20.
  • an igniter 11 is arranged, which in a manner known per se serves as an impact detonator and / or proximity fuse or time fuse is formed and detonates the explosive charge 12 carried by the explosive projectile 10.
  • the detonator 11 comprises a rear part 13 which, coaxially enclosed by the outer casing 19, projects into the explosive charge 12.
  • the z. B. have spherical shape and made of a suitable material such. B. steel or heavy metal. Tungsten and tungsten compounds are particularly suitable.
  • the splinter bodies 14 are preferably arranged between a fuse device 18 contained in the igniter 11 and the booster charge 15, in such a way that they surround an additional intermediate charge 16 in the form of a ring jacket, which pyrotechnically connects the transfer charge usually contained in the fuse device 18 with the booster charge 15.
  • the intermediate charge 16 is expediently cylindrical and surrounded by a tube 17. This arrangement ensures that after triggering the detonator 1 the ignition to the booster charge 15 takes place faster than the lateral energy spread through the explosive vapor.
  • the preformed splinter bodies 14 contained in the rear part 13 of the detonator 11 are already accelerated in the flight direction of the explosive projectile by the booster charge 15 ignited via the transfer charge 16.
  • the manufacture of the splinter carrier body can - as will be explained with reference to FIG. - be made substantially cheaper by the fact that the preformed splitter bodies 14, 20 are permanently embedded in a carrier body 21 made of a flexible plastic at a certain production stage.
  • the local distribution of the splinter body 14, 20 is freely selectable here.
  • a regular single-layer arrangement of preformed splinter bodies 14, 20 is shown. It is of course possible to provide an irregular local distribution and / or a multi-layer arrangement of preformed splinter bodies 14, 20, wherein splinter bodies 14, 20 with different weights or different external shapes can also be introduced into the carrier material 21.
  • the flexible plastic carrier 21 is placed in the required length in the form of an annular jacket around the transfer charge 17 arranged centrally axially in the igniter 11 and, if necessary, permanently connected to it by heat shrinking and / or gluing. Casting the splinter body in plastic is also possible.
  • the splinter body 20 in layer 19 "of the multi-part outer shell 19, 19 ', 19" can also be fixed in this way.
  • the splinter bodies 14 are arranged in front of the safety device 18 and booster charge 15 in the direction of flight of the explosive projectile.
