Definitions

  • the invention relates to a pyrotechnic impact detonator according to the Preamble of claim 1.
  • a pyrotechnic impact detonator is known from DE 196 51 169 A1.
  • anvil a commercially available secondary explosive that has been made especially ignitable 28 arranged. This secondary explosive is not defined in more detail.
  • the invention solves this problem according to claim 1.
  • a conventional explosive is used as the impact detonator with evenly distributed, defined cavities. Through these cavities with a diameter of 0.2 - 1.2 mm, the sensitivity of the explosive is below the sensitivity of tetryl. Tetryl is used as a secondary explosive denotes and does not require any special mechanical securing means, as is the case with conventional explosives built into detonators.
  • the cavities in the primary explosive are defined in a simple manner by Glass balls, styrofoam balls, addition of polyurethane, gas supply during casting or through holes that are transverse to the main axis of the explosive device.
  • the invention is based on the operating principle that when the projectile hits a shock wave initiation of explosives through imploding pores or Cavities occur in the explosives mixture.
  • an explosive projectile 1 consists of a casing 2 with a guide band 3, ground screw 4, a main charge 5 made of explosives and one Hood 6.
  • the hood 6 and an anvil 7 have a threaded ring 8 on the projectile side connected.
  • the anvil 7 has several ignition channels 10. These connect a hood-side Room 11 with a conical recess 12 of the anvil 7.
  • the ignition channels 10 are closed by foils 9 made of metal, such as aluminum.
  • a structured explosive 13, 15 made of PETN, nitropenta with cavities 16 lies in the space 11 and also the conical recess 12.
  • a conventional explosive can also be arranged in the recess.
  • the cavities 16 are defined by corresponding bodies made of polystyrene.
  • the ignition course of the explosive structured according to the invention is shown in FIG 13 at target mark 17 of floor 1.
  • phase 2 see reference number 23, the sources of fire 17.1 have expanded and form a detonation front 25 running in space 11, see also Figure 1.
  • a test body 30 made of PHX has a plastic bond Explosives, bores 32 lying transversely to its longitudinal axis 31.
  • the implementation of the explosive in detonation energy takes place in the direction of arrow 33. This is done in the same way as described for FIG. 2.
