Definitions

  • the invention relates to a stabilizing arrow projectile as a sub-caliber balancing projectile with the features of the preamble of patent claim 1.
  • a balancing projectile of the aforementioned type is known from US-A-4,353,305.
  • the intermediate body encloses preformed scattering projectiles in a shell or a metallic embedding.
  • the tip body When hitting an armored target, the tip body should develop a harmful effect in the form of a puncture or indentation against an outer target plate.
  • the scattering projectiles should be distributed behind the target plate in the form of a cone and thus include as large a space as possible in their harmful effects.
  • the regions of the tip and main body facing the intermediate body can be formed in a conical shape.
  • an explosive charge can be arranged in the central region of the intermediate body in order to increase the stray energy.
  • the scattering projectiles are intended to act jointly with fragments from the first target plate and the subsequent main body against a second target plate.
  • the disadvantage of this known balancing projectile is that its construction is complicated and complex in terms of production and costs; the preformed scattering projectiles affect the density of the intermediate body (if balls are used, the gusset spaces remain largely unused); the explosive charge affects the density of the intermediate body per se and also requires an igniter, which both complicates the structure and in addition also affects the density; the preformed scattering projectiles lead to a poor energy balance of the known balancing bullet in the target and restrict the adaptation to a given target situation.
  • an armor-projectile of short length is known, which is stabilized by gyroscopic action as a result of being fired from a tube provided with trains. It is a medium-caliber anti-aircraft projectile. When the bullet strikes light aluminum plates, either the entire bullet or at least the bullet tip and the central main part should dissolve into a cloud of daughter bullets mixed with parts of the aluminum armor. Such a projectile is not suitable for steel armor, in particular made of multi-layer armored plates.
  • the invention is therefore based on the object to improve a stabilizing arrow projectile of the type mentioned in such a way that it is simpler in construction and less expensive to manufacture, and that it has a good energy balance in the target due to the highest possible density and adapts itself to adaptation target-side conditions in particular is characterized in that it is not deflected from its flight path after the penetration g s in an armor especially when Schrägauftress on the armor and also does not break.
  • the rear part which is also the main part, is referred to throughout as the main body, the middle part as the intermediate body and the tip part as the tip body.
  • the balancing projectile according to the invention leads to a fragment scattering cone with a larger tip angle.
  • a significant part of the impact energy is converted into heat, which largely passes over to the particles formed from the material of the intermediate body and can thus lead to an additional fire effect of the particles.
  • a dense cloud is formed from numerous particles of favorable size distribution and this does not result in any disturbance of the main body in the multiple target.
  • an unspecified projectile consists of a main body 10 Intermediate body 12 and a tip body 14.
  • the main body 10 is connected to the intermediate body 12 in a flat butt joint region 16, for example by brazing or diffusion sintering.
  • a corresponding connection between the intermediate body 12 and the tip body 14 exists in a flat butt joint area 18.
  • the main body 10 and the tip body 14 are made of a tough material, the high density of which is achieved by a large proportion of tungsten or depleted uranium.
  • the intermediate body 12 preferably consists of a brittle sintered alloy with a large proportion of tungsten and the lowest possible proportion of a binder phase.
  • sintered bodies made of uranium powder are impregnated with the smallest possible amount of a metal or a metal alloy, the melting temperature of which is below that of the uranium. Both with tungsten and with uranium, a particularly high brittleness can advantageously be achieved in the non-impregnated region by impregnation with the relevant binder phase in a predeterminable radial extent in the circumferential region with sufficient strength of the intermediate body 12.
  • FIG. 2 differs from that of FIG. 1 only by a different design of an intermediate body 12 'and a tip body 14', which in turn are connected to each other in a flat butt joint area 18 'in the manner already mentioned.
  • the effect is increased by the fact that the heat generated at the target impact strikes largely on the particles, so that they have an additional fire effect.
  • the fire effect is particularly high when using the already pyrophoric uranium.
  • a further advantage results from the small size of the particles made of the material of the intermediate body 12; 12 ': they do not form a disruptive or distracting obstacle for the main body 10, which penetrates further into the target in the case of multiple armouring.
  • the comparatively smaller diameter of the flat butt joint region 18 'advantageously results in the possibility that a peripheral region of the intermediate body 12' on the joint region 18 'is already moving forward in the firing direction, so that the widening effect of the firing channel the material particles is reinforced.
  • a particularly favorable energy balance in the target results in a projectile according to the invention.
  • a better adaptation to target-specific circumstances, for example target design and target angle, is advantageously achieved.
  • Another particular advantage results from the simplicity of the floor structure, which is reflected in cost-effective production.
