Definitions

  • the invention relates to a spin-stabilized projectile with a payload according to the preamble of claim 1.
  • the object of the invention is to ensure as smooth and trouble-free ejection of the payload as possible. According to the invention, this is solved by the features in the characterizing part of patent claim 1.
  • the application of predetermined breaking points in the longitudinal direction in the effective space also has an advantageous effect, and, if a payload made of subprojectiles is used, the special coaxial arrangement of the subprojectiles and their securing against rotation during projectile acceleration through recesses on the projectile body in the area of the effective space.
  • a spin-stabilized projectile contains a projectile body 1, a ballistic hood 2 attached to the front of the projectile body 1 and a detonator 3 fastened to the rear part of the projectile body 1, which in this example is designed as a programmable timer 3.
  • a distance igniter for example a distance igniter, the ignition of which is triggered by transmission means.
  • the projectile body 1 also has an effective space 4 for a payload 5 fixed therein, a detonator space 6 arranged behind the effective space 4 and partially separated by a web 7, a guide band 8 and grooves 9 for attachment to a cartridge case, not shown, which is known per se .
  • a retaining screw 10 holds the payload 5 fixed in the axial direction and connects the projectile body 1 and the ballistic hood 2.
  • an explosive charge 17 is provided as the ejection charge 17, which is arranged in the radial direction with full contact in the detonator or time fuse 3 and / or in the projectile body 1 and in the axial direction with a damping distance 18 from the web 7.
  • the explosive charge 17 can be arranged directly in the projectile body 1 be, in which case the ignition chain to the detonator or timer 3 or detonator 16 must be ensured.
  • the damping distance 18 can be in the form of an air gap between the web 7 and the explosive charge 17, as shown in FIG. 1 or, for example, not shown, in the form of a material arranged between the web 7 and the explosive charge 17 with damping properties for the detonation shock wave.
  • the payload 5 consists of a large number of cylindrical sub-projectiles 20 made of heavy metal, which form 4 sub-projectile columns 21 in a coaxial arrangement in the active space. Eight subprojectiles 20 arranged one above the other form a column 21 and nineteen such columns 21, see FIG. 2, are firmly fixed in the effective space 4 by the retaining screw 10 in the axial direction.
  • the projectile body 1 is preferably formed in the region of the active space 4 as a hollow cylinder 22 with additional recesses 23 in the axial direction. According to FIG. 2, six recesses 23, which are eccentric in cross section, are provided here.
  • the mode of action of the spin-stabilized projectile is as follows: If the detonator 15 is fired, the payload 5 or the sub-projectile 20 is ejected via the detonator 16 and the explosive charge 17. Due to the arrangement of the explosive charge 17, the shock waves of the detonation have a temporal effect in the radial direction immediately and with a time delay in the axial direction. As a result, the projectile body 1 is torn open laterally in the region of the guide band 8 and the The active space 4 is opened laterally from behind along the predetermined breaking points 24, for example peeled like a banana, and its side parts, supported by the centrifugal forces, are flung away.
  • the payload 5 Due to the damping distance 18, the payload 5 is only slightly pressurized, as a result of which the release of the sub-projectiles 20 is delayed and practically trouble-free.
  • the subprojectiles made of heavy metal, shown as payload 5, then fly individually against each target in a twist-stabilized manner at an acute scattering angle.
  • FIG. 3 shows the coaxial arrangement of the nineteen sub-projectile columns 21 with their eight sub-projectiles 20 in the effective space 4 and the practically trouble-free ejection are very well documented.
  • the framed point spiral 25 can be traced back to a subprojectile column 21 with the greatest coaxial distance to the projectile axis and the point 26 to a subprojectile 20 resting on the web 7.
  • Sub projectiles of a different design and arrangement or, for generating false targets or for dazzling a flight destination, CHAFF or FLARE payloads can also be provided as payload 5.
