Definitions

  • the invention relates to a tip body according to claim 1.
  • the sabot in the vicinity of the front part of the balancing projectile has a comprehensive air pocket for detaching the segments of the sabot from the balancing projectile after leaving a weapon barrel under the incoming air.
  • an uneven detachment of the sabot segments from the balancing projectile was found. This can lead to a harmful swinging of the balancing bullet. Due to the oscillation of the balancing bullet, both its accuracy as well as its penetration performance can be significantly impaired.
  • the latter primarily relates to the effect against new types of targets, which require both particularly long balancing bullets and the greatest possible freedom of oscillation.
  • Investigations into the behavior of the balancing projectile-sabot arrangement showed that unstable flow conditions can occur in the area around the front part of the balancing projectile, which impair the uniform segment-wise detachment of the sabot.
  • the invention has for its object to provide a tip body of the type mentioned.
  • a balancing projectile 1 which is only partially shown, has a projectile tip 10 with a circular-conical region 12.
  • the projectile tip 10 is a substantially circular cylindrical plastic hood 14 with longitudinal axial recesses 13 and a retracted front face 15 pushed and glued.
  • the plastic hood 14 is supported with a rear inner surface 19 on a floor circumferential counter surface 18 and has an outer diameter 16 which approximately corresponds to a largest outer diameter 17 of the balancing bullet 1.
  • a body 20 is fastened on a projectile tip 11 which is only shown in sections.
  • a diameter 22 of the projectile tip is increased by a predeterminable amount in an area 21.
  • the body 20 is made of a material that is consumed by melting, softening and / or burning under the friction of the incoming air after leaving the gun barrel.
  • a material that is consumed by melting, softening and / or burning under the friction of the incoming air after leaving the gun barrel In addition to a thermoplastic, Wood's or Rose's metal or a magnesium alloy are suitable.
  • a balancing projectile sabot arrangement with one of the tip bodies 14 or 20 according to the invention leaves the weapon barrel in the direction of an arrow S, the tip body in question, owing to its respective diameter, prevents pressure fluctuations from interfering with the detaching process of the sabot segments.
  • an unfavorable c w coefficient in the top range is accepted.
  • the predetermined breaking points 13 take effect in the plastic hood 14 under the dynamic pressure of the air in the region of the inflow surface 16. The plastic fragments separate from the tip 10 of the floor and there is an instantaneous more favorable c w coefficient.
  • the more favorable c coefficient is established after the consumption of the material of the body 20.
  • the invention is characterized by good effectiveness with simplicity and low costs.
