Definitions

  • the invention relates to an explosive projectile with a projectile casing, which encloses a space filled with an explosive interior.
  • Such explosive projectiles are known for example from DE 21 26 351 and from DE-OS 28 37 638.
  • predetermined breaking points are introduced directly into the projectile casing to improve the splintering performance.
  • narrow areas of the projectile casing for example, are melted with laser or electron beams and then cooled in such a way that metallurgical structural changes occur along which the projectile later breaks.
  • a disadvantage of these known explosive projectiles that their production is relatively expensive and that thermally influenced by the strong heating and cooling of the near-surface areas of the projectile shell and underlying areas of the projectile shell, so that a sufficient launching strength of such projectile casings and thus the explosive projectiles often not guaranteed can be.
  • an explosive projectile is also known, in which for improving the splitter performance predetermined breaking points are not introduced directly into the projectile casing, but in separate cup-shaped steel sheet metal parts, which are located in this provided recesses of the projectile casing.
  • a warhead for the production of splinters of uniform size can be removed, wherein the embedded here between the warhead casing and the explosive shell liner has longitudinal holes, which together form a lattice Forming patterns.
  • the insert material proposed is unalloyed steel or reactive alloys. This measure ensures that the shock waves act unimpeded on all four cutting edges of the fragments to be formed and ensure reliable separation at these edges. Between the insert and the explosive a film is also provided here, which prevents penetration of the explosive into the longitudinal holes.
  • the invention has for its object to provide an explosive projectile which ensures a defined decomposition of the projectile casing by simple measures.
  • the invention is essentially based on the idea of arranging an insert made of a metal mesh, for example by gluing or pouring, in the region of the inner surface of the projectile casing. After ignition of the explosive, this metal mesh interferes with the further propagation of the explosive wave and leads to a defined manifold disassembly of the projectile casing.
  • the individual members of the metal fabric form additional construction splinters.
  • the metal fabric is a wire mesh or a metal mesh (for example, an expanded metal mesh). Further details and advantages of the invention will become apparent from the following, with reference to figures explained embodiments. Show it:
  • FIG. 1 shows the partially sectioned side view of an explosive projectile according to the invention with a arranged on the inner wall of the projectile casing wire ring fabric, the explosives has been omitted for clarity, and
  • FIG. 2 shows an enlarged cross section through the explosive projectile shown in FIG. 1 along the section line indicated there by M-II.
  • FIG. 1 denotes a large-caliber explosive projectile which has a projectile casing 2 which encloses an interior 4 filled with explosive 3 (FIG. 2).
  • an insert 6 consisting of a wire ring fabric is arranged in the region of the inner surface 5 of the projectile casing 2, wherein the individual rings welded together, for example, consist of stainless steel.
  • the insert 6 bent from an approximately flat mat forms wedge-shaped elevations 7 and depressions 8 with respect to the projectile casing 2, which support a defined decomposition of the projectile casing 2 after the ignition of the explosive 3, the rings of the projectile Wire mesh fabric 6 How light construction splinters work.
  • a wire mesh with a correspondingly selected (ie, the fragment size determining) mesh size can be used as insert for generating a defined decomposition of the projectile casing.

Abstract

L'invention concerne un projectile explosif (1) comportant une enveloppe de projectile (2) qui entoure un espace intérieur (4) rempli d'un explosif (3). L'invention vise à garantir une fragmentation définie de l'enveloppe de projectile (2) par l'application de mesures simples. A cet effet, un élément rapporté (6) en fil métallique est disposé dans la zone de la surface interne (5) de l'enveloppe de projectile (2), par exemple par collage ou coulage. Après l'allumage de l'explosif, ce fil métallique (6) gêne la propagation de l'onde de choc explosive et provoque ainsi une multiplication définie de la fragmentation de l'enveloppe de projectile (2), chaque élément du fil métallique (6) formant en outre des fragments supplémentaires.
