Definitions

  • the invention relates to a projectile core for a sabot projectile, which has a projectile core tip, a projectile core rear part and a projectile core middle part which are connected to one another by a projectile core mandrel, the projectile core middle part being produced from relatively brittle tungsten.
  • a brittle material for such projectile cores, a mandrel being located in the interior of the projectile core.
  • a pyrophoric material is used for the tip and the mandrel, in particular zirconium, titanium and their alloys.
  • Brittle tungsten or a brittle tungsten alloy with a compressive strength of e.g. 15,000 kg / cm2 and with a tensile strength of e.g. 800 kg / cm2.
  • an armor-piercing projectile (see GB-A-2 113 810) which has a main penetrator and a pre-penetrator, which are connected to one another by a tie rod.
  • the object to be achieved with the present invention is therefore to create a projectile core for a sabot projectile which is able to penetrate a number of plates of the target before it has completely disintegrated and lost its penetrating power.
  • the projectile core with which this object is achieved is characterized in that the projectile core mandrel has an armor-piercing tip and is made of a relatively ductile armor-piercing material. Tungsten is preferably used for the projectile core mandrel, which is ductile enough not to completely disintegrate when penetrating a first plate of the target.
  • the projectile core according to the invention has the advantage that the armor-piercing projectile core mandrel is able to penetrate several plates before it completely disintegrates and loses its penetrating power.
  • the projectile core 10 for a sabot projectile consists of a projectile core mandrel 11, a projectile core tip 12, a projectile core rear part 13 and a projectile core middle part 14.
  • the projectile core 10 should be designed in such a way that it is suitable for combating targets which consist of a number of plates arranged at a distance from one another, as shown in FIG. 2-4.
  • a relatively brittle projectile core 15 disintegrates, as it has been used so far, when penetrating a first plate 16 to the extent that it is no longer able to penetrate a second plate 17.
  • the relatively brittle middle part 14 of the projectile core also disintegrates when it penetrates the first plate 16. Thanks to the inventive design of the projectile core mandrel 11, however, the projectile core 10 is still able to penetrate the second plate 17.
  • the storey core 10 according to the invention of a sabot projectile is particularly suitable for targets in which e.g. three plates 16, 17 and 18 or other plates are arranged one behind the other.
  • brittle tungsten so-called frangible material, with small elongation (against 0%) was used, which is arranged between the ballistic projectile core tip and the projectile core rear part.
  • This well-known storey core is unable to achieve inhomogeneous or heterogeneous targets - i.e. To penetrate targets consisting of several plates spaced apart from each other, because the brittle tungsten already fragments after penetrating the first plate.
  • Projectile core middle part 14 made of tungsten uses an armor-piercing projectile core mandrel 11, which is also made of tungsten, but has a higher elasticity of, for example, 2-20%.
  • This projectile core mandrel 11 does not fragment, but continuously degrades on the further plates, it thus forms a penetrator for targets which consist of several plates 16-18 arranged at a distance from one another.
  • the projectile core 10 according to the invention thus achieves an excellent effect on soft, medium-hard and inhomogeneous or heterogeneous targets.
  • the projectile is therefore suitable for anti-aircraft and final combat.
  • the tip 19 of the projectile core mandrel 11 is shaped such that it is particularly suitable for penetrating plates 16-18.
