Definitions

  • the invention relates to a warhead with an ignition device and a projectile-forming charge.
  • the projectile-forming charge usually consists of a flat-cone charge, i. a generally dammed explosive charge having a front-side cavity seen in the main direction of action into which a conical insert of e.g. Copper or soft iron is inserted. After ignition of the explosive detonation wave causes a deformation of the insert, so that there is a projectile, which is stabilized by a corresponding rear expansion during its flight.
  • a flat-cone charge i. a generally dammed explosive charge having a front-side cavity seen in the main direction of action into which a conical insert of e.g. Copper or soft iron is inserted.
  • the US 4,665,826 A concerns a warhead with a projectile-forming charge.
  • the actual acting body is inside a double-walled tube.
  • the second shell sheath / protective cover
  • the resulting active body itself will not be described in detail.
  • the invention has for its object to provide a warhead of the type mentioned, in which the projectile-forming charge a projectile is formed by explosive deformation, which has a secondary performance in the target, which is not only greater than that of comparable projectile-forming charges, but also comparable KE -Ammunition.
  • the invention is based essentially on the idea not to produce the projectile by the action of the detonation wave on a flat cone insert, but on a metal tube, preferably made of steel, tungsten, tantalum or copper, whose axis of symmetry is arranged in the main direction of action of the projectile to be generated ,
  • the metal tube is surrounded at least in some areas by a dammed explosive charge, so that the detonation wave after ignition of the explosive charge acts on the metal tube that this is compacted with respect to the main direction of action from back to front to a projectile and accelerated in the said direction.
  • the metal tube is lined on the inside with a lower-density liner tube, preferably made of aluminum or magnesium.
  • a lower-density liner tube preferably made of aluminum or magnesium.
  • the cavity of the metal tube is filled with a powder, for example of aluminum particles, wherein the grain size of the powder should be between 0.3 mm and 5 mm.
  • the warhead according to the invention can preferably be used in multi-purpose projectiles.
  • the damming of the explosive charge needs to be designed as a splinter shell.
  • the explosive disposed between the metal tube and the splinter shell then causes a much greater explosive effect than in the comparable, provided with a flat cone insert multi-purpose projectiles.
  • Fig. 1 is denoted by 1 a stabilizer stabilized multi-purpose projectile, which has on the rear side a hinged tail 2 and on the front side a projectile body 3.
  • the projectile body 3 comprises a projectile envelope 4 designed as a fragment envelope.
  • an ignition device 5 at the rear, to which a metal tube 7 made of steel with a deposit tube 8 made of aluminum connects in the direction of the axis of symmetry 6 of the projectile 1 on the front side.
  • the axis of symmetry 6 of the projectile 1 and the symmetry axis 9 of the metal tube 7 coincide.
  • the ignition device 5 and the metal tube 7 are rotationally symmetrical surrounded by an explosive charge 10, consisting of a plastic-bonded explosive.
  • a detonation shaft link 18 is arranged between the ignition device 5 and the metal tube 7 ( Fig.2 ).
  • the ignition device 5 is activated, which in turn ignites the explosive charge 10. This results in highly stressed gases 11, which compact the metal tube 7 and the deposit tube 8 therein progressively from back to front.
  • the detonation waveguide 18 ensures by deflecting the detonation wavefront for a symmetrical compaction.
  • the detonation wavefront marked 12 acts axially on the step-shaped transition region 13 between the already compacted tube region 14 and the not yet compacted tube region 15, so that the forming projectile is accelerated simultaneously in the direction of the symmetry axes 6 and 9. This results in a relatively long projectile of high velocity and thus high kinetic energy, which breaks through the armored target and has an extraordinarily high secondary performance.
  • the likewise compacted liner tube causes above all a density gradient in the penetrator and leads to an increase in the secondary effect.
  • the invention is of course not limited to the embodiments described above.
  • the projectile casing front thin-walled than in the remaining area of the projectile body are formed or remain open there, so that the accelerated projectile exits through the projectile casing as unhindered.
  • the metal tube may be formed at its ends both open and closed. Open, it is especially formed when a granular substance is used so that it is not “blown away”. Closed, however, it is especially trained when a pipe is used as an insert.
