Definitions

  • the invention relates Sectionzerlegungs- and deformation bullets with identical Treffigelage, and a method for their preparation.
  • a subdivision projectile is for example from the DE 199 30 475 A1 , a deformation bullet for handguns from the DE 100 10 500 A1 known.
  • the object of the invention is to introduce partial disintegration projectiles and deformation projectiles, which have despite different effect in the same handling of the weapon, with the same focus on the target, the same Treffigelage in the target point.
  • the materials of the projectile body are composed of 55% to 99% copper and 1% to 45% zinc. About the zinc content, the toughness of the projectile body
  • the alloy of the partial decomposition projectile and the alloy of the deformation bullet must be matched to one another.
  • the shape of the cavity contributes significantly to the Zerlege the respective projectile body: the combination of conical and cylindrical sections, including the shaft bore counts, and the choice of the opening angle of the conical sections.
  • a conical section may additionally be provided in front of the shaft bore, the conical angle of which is different from that of the preceding conical part.
  • the projectile structures according to the invention have the same Treffigelage and allow despite different effects in the target point the same handling of the weapon, d. H. the same sighting of the target point.
  • Both bullet types 1 and 2 have in the projectile nose 3 on a cavity 4, which is closed by a cap 5 made of plastic or a lead-free material.
  • the cap 5 has a double cone shape with a rounded tip 6, which projects from the projectile 1, 2 and at the opposite side a shaft 7, which extends into a bore 8 in the projectile 1, 2, which adjoins the cavity 4.
  • the deformation bullet 1 has a length of about 5 mm and the partial separation projectile a length of about 6.4 mm.
  • the bore 8 has about twice the length of the shaft 7 extending into the bore, which here is about 8.5 mm long, and has a diameter of about 2 mm.
  • the shaft-side cone 9 of the cap 5 and thus the opening 10 of the cavity 4 have in the present embodiment an angle of about 40 degrees. Depending on the caliber, this angle can vary between about 30 and 50 degrees.
  • the bearing surface 11 on the projectile edge, the opening 10, has a length of about 1 mm, which may vary by a few tenths of a millimeter depending on the caliber.
  • a cylindrical portion 12 of the cavity 4 connects, which is about 2 mm long and may also vary by a few tenths of a millimeter depending on the caliber. Its diameter here is about 4.75 mm and can also vary depending on the caliber by a few tenths of a millimeter.
  • a conical section 13 of the cavity 4 which is about 2 mm long. Its length can also vary by a few tenths of a millimeter.
  • the cone angle is 70 degrees. Also he can vary depending on the caliber of about 60 to 80 degrees.
  • a sharp edge 14 marks approximately the transition of the conical portion 15 of the projectile 1, 2 to the cylindrical portion 16.
  • the projectile 1, 2 has on the cylindrical portion 16 relief grooves 17 and the rear 18 may have a tail cone 19.
  • the outer volume is the same for both the deformation level 1 and the partial separation level 2.
  • the partial decomposition projectile 2 after FIG. 3 differs in the embodiment of the cavity 4 by a further conical portion 20 in front of the shaft bore 8 and a circumferential notch 21 as a predetermined breaking point at the beginning of this conical portion 20.
  • the cone angle is 30 degrees and depending on the caliber of about 20 to 40 degrees vary.
  • the length of this conical portion 20 of the cavity 4 is about 2 mm to 3 mm, depending on the caliber, preferably about 2.5 mm.
  • the material composition in the deformation projectile 1 would be 70% Cu and 30% Zn and in the partial decomposition projectile 2 62% Cu and 38% Zn.
  • the material composition of the sub-decomposition projectile 2 must be tuned by adding the element lead with a share up to 4 percent by weight to the alloy.
  • the principle of action of the projectiles 1 and 2 can be described as follows: When a projectile hits the target, the cap 5 dives into the cavity 4 via its rear conical surface 9 and thus initiates the deformation. As a result, the edge 22 of the opening 10 of the cavity 4 is exposed and forms a cutting ring. This cutting ring exerts a punching effect when hitting a tissue and penetrates into the tissue. The inflowing tissue causes the deformation to the final shape due to the hydrodynamic pressure.
  • FIG. 2 can be seen in which a deformation bullet 1 is shown after hitting a soft body. The top of the projectile is compressed, but has not disassembled.
  • FIG. 4 is a partial decomposition bullet presented after hitting a soft body. When mushrooming, the conical portion of the projectile split into individual fragments.
  • the deformation is thus dependent on the flow velocity of the tissue, according to the projectile velocity, and thereby acting on the material forces.
  • the effect of the forces is influenced by the described different configuration of the cavities in the floors and the respective material properties.
