Definitions

  • the invention relates to a military charge of the type with symmetry of revolution about a longitudinal axis, comprising a weakened cylindrical envelope, containing an external explosive mass and an internal explosive mass provided with a priming relay.
  • This invention concerning the military charges used in missiles, finds a particularly important application, although not exclusive, during interceptions of airplanes and missiles whose structural destruction occurs from a known value of the ratio between the kinetic energy of the fragments piercing the target and its surface receiving these impacts.
  • the shrapnel it is appropriate for the shrapnel to have the same mass, be animated at the same speed and arrive simultaneously on the target, according to substantially parallel trajectories, contained in the envelope of the meridian planes of the load. , limited to the length thereof.
  • the formation of the cylindrical detonation wave ensures that the fragments are put into simultaneous speed, thus meeting the destruction criteria defined above.
  • a military charge of the type defined above is known, the explosive mass of which is designed to generate a cylindrical detonation when it reaches said envelope (FR-A-2 280 053).
  • the internal stage consists of rapid and slow explosive compositions. Since the ratio between the thickness of the rapid explosive composition and the thickness of the slow explosive composition varies with the distance from the relay, it is impossible to apply constant energy to the external mass over the entire axial length of this mass.
  • the invention aims to provide a charge of the type defined above making it possible to obtain flashes of the same energy.
  • the explosive mass may include a central cavity, possibly occupied by a dense nucleus.
  • the outer casing will generally be made of steel or light alloy, although it is also possible to envisage the use of various dense materials and alloys.
  • the priming relay By dividing the mass into an internal frustoconical stage externally coated with a metallic coating radially separated from an external cylindrical annular stage surrounding the first, the priming relay being placed at the top of the cone, it is possible to carry out the charge at using a single explosive composition.
  • Two frustoconical stages can be associated symmetrically according to the requirements of size and elongation, the pyrotechnic relay being placed at their top.
  • the charge shown in solid lines in FIG. 1, of the multi-stage type comprises a thick casing 10 for forming flakes containing a mass of explosive composition.
  • This mass consists of an external block or stage 12 of cylindrical annular shape and an internal block or stage 14 whose external surface is of frustoconical shape.
  • Stage 14 is provided with a metallic coating which is projected onto the second stage 12 initiated by impact.
  • a pyrotechnic relay 18 is placed against the small base of the internal stage 14.
  • the conicity of the casing 16 is provided so that it takes a cylindrical configuration before impact on the stage 12. After priming of the stage 12 , the envelope 16 plays the role of dynamic confinement and, consequently, makes the explosive of stage 12 work with better efficiency.
  • the central cavity 20 of the block may be occupied by a dense core; its geometry can, moreover, reduce side effects.
  • Flanges 22 can be provided to further reduce the edge effects, moreover more reduced in the case of a divergent cylindrical detonation wave than in the case of a sweeping detonation wave.
  • the explosion of the stage 12 creates in the envelope 10 stresses which are essentially circumferential and radial.
  • pre-fragmentation lines constituted by large circles 24 and generators 26 will be used. obtained by any of the usual means, in particular by cutting the wall and / or by local change in metallurgical structure obtained by localized heating, in particular using an electron beam.
  • the axial weakening lines can be offset when passing from a crown delimited by two circles 24 to the next crown, so as to be placed along a helix 28, as shown diagrammatically in FIG. 2.
  • This solution is particularly advantageous when several type modules are shown side by side shown in FIG. 1, the relays 18 of which are associated with a priming system which allows at will to control either all the relays simultaneously, or only the central relay. In the latter case, the fragmentation of the envelope is favored since there is a full field of axial, radial and circumferential stresses.
