Definitions

  • the invention relates to a projectile body as defined in the preamble of the claim.
  • the projectiles are provided with one or - for reasons of stress and deformation - also several guide bands arranged one behind the other to transmit the swirl.
  • the diameter of the guide bands is such that they press into the trains as the bullet passes through the tube.
  • the guide tapes can e.g. B. made of copper, soft iron or plastic.
  • the projectile is particularly sensitive to radial pressure, since large stresses on the material can occur at the points depending on the projectile geometry. This allows the shell to be are pressed inwards and the seal against the propellant gases usually guaranteed by the guide band is no longer guaranteed.
  • a solid core projectile is also known from DE-C 731 064, the relatively wide guide band of which has several sections for receiving the sheared material. The problem of the deflection of the casing due to the axial guide band pressure does not arise with this projectile.
  • the present invention is therefore based on the object of specifying a projectile body of the type mentioned in the introduction, in which, when using thin-walled casings, a better sealing against the gas pressure takes place.
  • the invention is therefore based on the idea of providing relief at the points in the region of the guide band where the bullet casing is subjected to high stress in the radial direction.
  • the axial extent of the relief grooves depends on the rigidity of the shell and should be> 4 mm for artillery shells with metal guide bands.
  • Fig. 1 denotes a projectile body, 2 the projectile casing and 3 the guide band.
  • the guide band 3 is dimensioned so that it fully presses into the trains when the projectile passes through the tube. It transmits the swirl to the floor via the rail guide of the trains and at the same time seals against the powder gases.
  • the projectile 1 has a cavity 4 inside, in which, for. B. a brake parachute, not shown, can be accommodated.
  • Fig. 2, 2 again designates the projectile shell on which the guide band 3 according to the invention is arranged.
  • the grooves denoted by 31 to 34 serve in a known manner to accommodate the guide band material which also shears off at the rear when the projectile body passes through the tube.
  • the radial contact between the tube and the guide band 3 exists only at the guide band rings 36 to 41.
  • the dashed curve 300 shows the guide band pressure distribution for a guide band without grooves according to the storey structure with cavity 4 shown in FIG. 1. It can clearly be seen that a maximum guide band pressure occurs approximately in the middle of the guide band.
  • This groove must be provided in this area.
  • This groove was designated 35 in FIG. Their width B should be wider than 4 mm.
  • the width B should be between 6 and 20 mm, depending on the type of the projectile. However, it should be taken into account that the total width of the guide band rings in such projectiles should be approximately 20 mm (typically, guide bands have a width of 38-40 mm).
  • the step curve 301 in FIG. 3 gives approximately the pressure distribution of the guide belt 3 according to FIG. Fig. 2 again. Due to the relief groove 35, the guide band pressure drops significantly in this area.
