Definitions

  • the invention relates to a fragmentation shell for ammunition according to the preamble of claim 1.
  • the invention has for its object to provide measures in a splinter shell, the fragment sizes largely defined when the explosive detonates leads.
  • a shell 1 shows in its inner wall 2 plate-shaped, sharp-edged splinters 3 made of heavy metal or high-strength steel
  • the splitters 3 are by a Pressing process molded into the inner wall 2.
  • the shell is subject to 1 - starting from the edges 4 - stress zones 5.
  • the advantage is also achieved that Stress zones 5 the shaping of the projectile shell 1 into fragments takes place more quickly and less energy is required for fragmentation from the shell 1.
  • An adhesive 7 serves as an additional fastening means for the splitters 3 with one another and for the splitter 3 for attachment to the shell 1 view is sufficient for the attachment of the splinters 3 on the projectile casing 1 the impression.
  • the adhesive 7 also serves to increase the fragmentation speed in which the Cavities 7 are filled by the adhesive 7. An energy consuming deformation the splinter 3 is blown into the cavities 9,9.1,9.2 by the explosive pressure largely avoided.
  • the splitters 3 according to FIG. 2 are either individual splitters, notched on their outer side 13 Splinter rings or 13 notched fragment spirals 24 on their outside.
  • the embedding material for the splitters 3 or split rings 10 or split helix 11, which is designated as adhesive 7, corresponds or largely corresponds to that Density and strength of the fragments 3 or the fragment rings 10 or the fragment spiral 11.
  • the embedding material or filler material therefore has the same shock wave impedance, like the splinters 3 on.
  • This is characterized by an embedding material Tungsten carbide, optionally with a binder component or by adding a metal component reached in a binder.
  • the cavities 9, 9.1, 9.2 between the splitters 3 with one another or between the splinters 3, the splinter rings 10, the splinter spiral 11 relative to the splinter shirt 8 or the fragment cover 1 are with the adhesive 7 or an embedding material, filled in as described above.
  • An energy consuming deformation of the Splitter 3 or the not shown splitter of the pre-notched splinter rings 10 or the fragment spiral 11 into the cavities 9, 9.1, 9.2 largely avoided. This will significantly increase the fragmentation speed reached.
  • hard splinters 3 which are harder than the shell 1 is due to Pre-notching, i.e. partial deformation, in the pressing process or calibration process in the edge area of the shell 1 before.
  • a fragment ring 10 or a fragment spiral 11 on their the explosive charge facing inside 6 according to FIG. 5 notches 12 on the the disassembly of the fragment rings 10 or the assembled into a package Favor fragment spiral 11 to individual fragments.
  • the sharp-edged splinter rings 10 and the fragment helix 11 are calibrated after it has been introduced into the projectile casing 1, so that after calibration ring-shaped tension zones 5 arise in the projectile casing 1 and / or caused by the explosive pressure in the shell 1.
