Definitions

  • the invention relates to a swirl-stabilized carrier projectile provided with a guide band, as defined in more detail in the preamble of the patent claim.
  • the projectiles are provided with guide bands for transmitting 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 band is usually arranged either on the floor or on the shell of the projectile. If the guide band is on the floor, the twist transmission between the floor and the casing is usually carried out via a pin or screw connection.
  • the screw connection was previously used for thick-walled casings.
  • the pin connection has advantages over thin-walled sleeves. A large number of pins are arranged over the circumference in order to ensure a secure swirl transmission in the pin connection. This requires a relatively large ejection charge to shear the pins when the submunitions are ejected.
  • the guide band is arranged on the projectile casing, a relatively complex radial support structure of the casing in the guide band area is required. Otherwise, the sealing function of the guide band would not be guaranteed due to the large radial compressive forces of the tube on the guide band.
  • the projectile is particularly sensitive to radial pressure, since large stresses on the material can occur at locations dependent on the projectile geometry.
  • the present invention is therefore based on the object of specifying a carrier projectile of the type mentioned at the beginning, in which on the one hand the swirl transmission between the casing and the floor is eliminated and in which on the other hand a complex support structure of the casing in the guide band area is not required.
  • the invention is therefore based on the idea of distributing the guide band over the shell and floor, so that a direct swirl transmission takes place in both storey components. Due to a guide band distribution corresponding to the axial inertia conditions, the previously required twist transmission between the shell and the bottom is eliminated.
  • the connection between the shell and the bottom can therefore be designed to meet emissions requirements (e.g. only two instead of 8 dowel pins) and thus one Contributing to the minimization of the projectile load during ejection.
  • 10 is a carrier floor. At the rear end of the carrier floor 10 there is a floor 11, which is connected to the shell 12 of the carrier floor 10 via shear pins 13.
  • Submunition bodies may be located in the interior of the carrier projectile, the rear-side submunition body, which is only shown schematically, being indicated by 15.
  • the guide band 14 is dimensioned so that it fully presses into the trains when the projectile passes through the tube. It transmits the swirl to the floor 11 via the strip guide of the trains and via the shear pins 13 to the floor case 12.
  • the submunition projectiles 15 are ejected by, for example, igniting a pyrotechnic charge in the bow-side part of the carrier projectile 10, which pushes the submunition projectiles 15 backwards so that it is at a sufficiently high pressure to shear the pins 13 is coming.
  • the guide band is composed of two partial guide bands 140 and 141.
  • the first part guide band 140 is arranged on the floor 11 and the second part guide band 141 on the floor case 12.
  • the guide band causes a direct swirl transmission both to the floor 11 and to the shell 12.
  • the swirl transmission between the shell 12 and the floor 11, which is usually necessary, is therefore eliminated.
  • the number of shear pins can be reduced compared to conventional carrier projectiles 10 (e.g. Only two pins may be required), and consequently the ejection charge required to shear the pins can be significantly reduced. Ultimately, this leads to a considerable reduction in the projectile load during ejection.
  • the guide band 140 located on the floor 11 could e.g. B. made of copper and the guide band 141 located on the sleeve 12 are made of soft iron.
  • the guide band 140 located on the floor 11 and fasten the partial guide band 141 to the cover 12 with three welds.
  • the different materials and types of fastening shown by way of example are chosen because the thin wall of the casing does not allow the partial guide band 141 made of copper to be shrunk on and a soft iron guide band must be used instead.
  • the floor 11, on the other hand allows the shrinking of a partial guide band 140 made of copper thanks to the greater wall thickness. In general, copper is preferred as the belt material because it causes less tube wear.
