Definitions

  • the invention relates to an insert for a warhead, the type defined in the preamble of claim 1.
  • a warhead with an insert which is designed as a spherical cap is known from US Pat. No. 4,356,770.
  • This spherical cap creates an essentially rod-shaped projectile through explosive deformation, but due to its aerodynamically unfavorable shape it has unstable flight behavior, a high drop in speed and consequently an inadequate end-ballistic performance.
  • the high drop in speed is essentially caused by the hemispherical shape of the projectile tip.
  • a projectile-forming insert corresponding to the features of the preamble of patent claim 1 can be seen as known.
  • this insert which consists of a basic cone
  • a central area of the insert contains a cone which deviates from the basic cone and has an acute cone angle.
  • this causes the tip area to break out of the remaining part of the projectile during explosive forming.
  • the aim of this is to create two partial storeys, with the leading partial storey formed from the tip area penetrating the camouflage layer of armor and thus creating an opening through which the subsequent storey can fly unhindered and without impairing its penetration effect.
  • the disadvantageous shape present here in particular the main part of the projectile, does not guarantee an increase in the final ballistic performance.
  • FIG. 1 shows an essentially hollow-cylindrical warhead 10, in the housing 11 of which an explosive charge 13 activated by an igniter 12 is arranged.
  • the explosive charge 13 is delimited on one side by a dome-shaped insert 14, from which a projectile can be formed by explosive deformation.
  • the insert 14 has the shape of a spherical cap.
  • the projectile shown schematically in FIG. 1 with 15 can be produced from such an insert by the explosive shaping after ignition of the explosive charge 13. Such projectiles have a strong drop in speed, which is due to the aerodynamically unfavorable shape of the tip of the projectile 15. As shown in FIG. 1, the insert 14 creates a projectile 15 with a tip in the shape of a hemisphere.
  • FIG. 2 shows an insert 20 which, apart from a central area 22, essentially corresponds to the insert 14 (FIG. 1).
  • the insert In the area 22 around the center of the insert, the insert has a stronger convex curvature in the direction of the explosive 13 (FIG. 1) than outside the area 22.
  • the geometric change in the area 22 of the insert can have any shape (linear, square, S-shaped, etc.) such that the radial pressure components pr at the edge of the area 22 are larger within this area than the radial pressure components p'r outside of area 22 but also in the immediate vicinity of this area.
  • the height ⁇ x of the curvature and the diameter d of the area 22 up to which the geometric change is made depend on the explosive used and the insert material and must each be determined experimentally.
  • the maximum diameter d of the area 22 is approximately 10 to 25% of the diameter D of the insert 20 and the height ⁇ x of the bulge (indentation) must be less than 15 in this area % of the curvature of the insert 20.
  • the wall thickness s of the insert within the area around the insert center can be selected to be at least in a partial area smaller than the wall thickness of the insert outside of the said area.
  • a corresponding exemplary embodiment is shown in FIG. 3.
  • the insert 40 was the insert and 50 the projectile resulting from the insert 40 being exploded.
  • the area 42 around the insert center corresponds to the area 22 in FIG. 2.
  • the insert geometry is changed in a partial area 43 such that the corresponding diameter s is smaller than the diameter S of the insert outside the area 42.
  • the remaining one Wall thickness of the insert in area 43 must, however, be selected so that the insert does not burst in the case of particularly explosive explosives.
