Definitions

  • the invention relates to a shaped charge specified in the preamble of claim 1 and u. a. through DE 36 23 240 C1.
  • the shaped charge according to the last-mentioned patent serves to disarm ammunition of various types.
  • components are attached to their charge housing on the side of the charge liner, leaving a free space for perfect spike formation. Due to their nature and shape, they are able to reduce in a predetermined manner the breakdown performance of the shaped charge spike formed in the event of a detonation from the collapsing charge lining. The extent of the reduction in performance is such that the hot, high-density spiked particles should only be able to cause a locally limited reaction or deflagration when the ammunition explosive charge has broken through.
  • the invention has for its object to improve a shaped charge of the type mentioned in such a way that it can be used to quickly open ammunition cases or other containers of sensitive content, for example in disarming or disposal activities, as well as for quickly opening doors or other barriers, for example during operations of fire brigades and special technical troops, no longer need a shaped charge of hot particles of high density and therefore no risk for users and the environment.
  • the measures taken according to the invention are very easy to implement. Where this happens, the result is a hollow charge that is ideally suited for contact-free use, with which envelopes of explosive charges or other containers of comparable critical content, as well as locked doors and other barriers, can be dynamically softly penetrated without splintering.
  • a shaped charge spike made of flowable medium such as water with or without antifreeze, oil, gel or liquid glass.
  • a relatively small amount of charge is sufficient to form the same.
  • Adequate fluid or gel acceleration can e.g. can already be achieved with an explosive foil covering on the lining side facing away from the liquid or gel filling.
  • the liner in question preferably one made of a non-metallic, specifically light material, only functions as a shaping separating layer between the flowable medium and charge occupancy and, due to its shape, works together with the latter to focus the flowable medium into a shaped charge.
  • a malleable explosive is assigned to the central plug for pyrotechnic acceleration on its side facing away from the lining, it is easy to use it for the ring-shaped detonation initiation into the charge.
  • charge covering made of explosive film the latter only needs to be arranged concentrically with one end section around the explosive that can be ignited, for example, by a detonator of a known type.
  • a housing made of polyurethane or the like can be used for igniters that are harmless to magnetic field changes.
  • the single figure shows in longitudinal section a charge housing 1 made of plastic, such as polyurethane or styrofoam, which can accommodate a sighting device at 2. Inside there is a shaped charge 3 with a lined charge cavity 4. Its charge and liner are designated 5 and 6 in the order mentioned.
  • the lining 6 consists of a plastic. It has the shape of a funnel 6a, which is open on both sides, with a cylindrical extension 6c at the funnel end remote from its base 6b.
  • a section 5a of this explosive film 5 is arranged concentrically around the cylindrical extension 6c of the lining funnel 6a.
  • the detonating explosive 8 opens the two cavity closures 7 and 10 and, with the closure plug 7 which is strongly accelerated by it, displaces water 11 from the center of the cavity 4 at high speed.
  • the free space thus obtained is the jet formation from the non-displaced Part of the water filling 11 useful.
