Definitions

  • the invention relates to an igniter for a projectile-forming charge according to the preamble of claim 1.
  • a central or axial ignition location is required for projectile formation and two ignition locations diametrically opposite one another in the area of the circumference of the explosive charge for the splinter formation.
  • the object of the invention is therefore to propose a simple detonator for a projectile or splinter-forming or spike-forming charge, which ensures that the two ignition sites required for splintering are ignited simultaneously in the area of the charge.
  • the invention solves this problem according to the characterizing features of claim 1. Advantageous further developments can be found in the subclaims.
  • the selection of the ignition locations can be achieved in the microsecond range, that is to say almost without delay.
  • the detonator according to the invention is therefore suitable for all ammunition in which an interaction is provided and in which the selection for the special ammunition effect must be made within a very short time.
  • Such a type of ammunition is a sensor-fired projectile charge, which usually has no prior knowledge of the type of target to be combated and the type of control must be decided within microseconds after the target has been grasped.
  • the detonator necessary for the formation of fragments is ignited.
  • the ignition tube then initiates the simultaneous ignition of the two booster charges arranged in the area of the circumference of the charge.
  • the detonator which is decisive for the projectile-forming charge is fired.
  • a projectile-forming insert 2 In a casing 1, a projectile-forming insert 2, an explosive charge 3, a cover plate 4 and a slide 5 with two electrically ignitable detonators 6, 7 are arranged at a distance 9 or in a radius 25.
  • the cover plate 4 there are bores 11-13 with reinforcing charges 15-17 arranged therein and an ignition channel 18 which is V-shaped at a lateral safety distance 10 from the reinforcing charge 15 and which has a rapidly reacting transfer charge 19 such as explosive.
  • the ignition channel 18 is incorporated in the cover plate 4 and lined with a layer 20 made of a shock wave-reducing, porous plastic, such as polytetrafluoroethylene.
  • the ignition channel 18 is constructed so that on the one hand the ignition is ensured, on the other hand the impact energy within the ignition tube formed by the plastic is reduced to such an extent that neither the premature ignition of the central booster charge 15 nor that of the explosive charge 3 takes place under the ignition channel.
  • the slider 5 assumes the position shown only in the focused position. Otherwise, the slide 5 is in the safe position 8.
  • the electrically triggered detonator 6 ignites the booster charge 15 and this the explosive charge 3. This forms - in a manner known per se - an armor-piercing projectile from the insert 2.
  • the electrically triggered detonator 7 ignites the transfer charge 19 and this, via the bores 12 and 13, the explosive charge 3 for the known shaping of the insert 2 into breakdown-relevant fragments.
  • the opposing ignition locations 23 and 24 result in overlapping shock waves in the explosive and thus at the insert 2 there are very different energy conversion potentials per unit area and speed factors. This creates splinters.
