Definitions

  • the invention relates to cartridge ammunition according to the preamble of claim 1.
  • the invention is therefore based on the object of specifying a cartridge ammunition in which the connection between the sub-caliber projectile and the combustible propellant charge sleeve is designed to be considerably simpler and easier to manufacture with the same load capacity. This object is achieved by the invention specified in claim 1.
  • the invention is characterized in particular by the fact that a secure connection between the sub-caliber projectile and the propellant charge sleeve made of combustible material is achieved by simply plugging it on. This considerably simplifies assembly and the saving of the screws considerably reduces the cost of producing the cartridge ammunition. Finally, in contrast to the known solution, in which the propellant charge sleeve had to be formed in two parts to carry out the screw connection, it can be formed in one piece. This saves another operation that was previously necessary to complete the propellant charge sleeve.
  • Fig. 1 shows a longitudinal section of a portion of a cartridge ammunition 10, which consists of a sub-caliber projectile 11, a sabot 12 concentrically surrounding the projectile and a combustible propellant charge sleeve, of which a section is shown in Fig. 1, namely the cartridge cover designated 23 .
  • the propellant charge sleeve is connected to the projectile 11 in the region of the cartridge cover 23 via a snap-in connection.
  • the latching connection is formed by resiliently inwardly projecting parts 18 of the bead-like bent cartridge cover 23, which rest on shape-matching surfaces 20, 21, 24 in the rear part of the sabot.
  • Fig. 2 These form-fitting surfaces are shown in Fig. 2. They initially consist of the surface 24 of an annular trench-shaped depression 26 which is embedded in the rear part of the sabot 12, further of a truncated cone-shaped surface 20 which adjoins the surface 24 in the radial direction inwards, and finally of the surface 21 of a step 15 in the rear-shaped part of the sabot 12. Just as in the radial direction inwards, the surface 24 also merges in the radial direction outwards into a conical surface 25.
  • the correspondingly adapted surfaces of the cartridge cover 23 bear against the aforementioned surface parts during the connection process, in such a way that the bead 19 of the cartridge cover 23 is supported on the surface of the annular trench-shaped depression 26 and in part also on the surface 25, while the part 18 of the cartridge cover 23 rests over the entire surface of the conical surface 20 and, after the snap-in process, also sits with its end piece on the surface 21 of step 15.
  • the rear part of the sabot 12, which carries a guide belt 13 in a known manner, is covered over the entire area with a seal 14 towards the rear.
  • This seal is suitably made of silicone rubber, which is vulcanized onto the sabot rear.
  • the aforementioned mating surfaces, against which the parts of the cartridge cover rest, are arranged according to the invention in this seal 14.
  • the material of the seal yields and thus enables the parts of the cartridge cover 23 to be positively attached to the seal 14.
  • the surface 24 of the annular trench-shaped recess 26 extends conically in the radial direction as well as outwards Areas 24 and 20 over.
  • the surface 20 forms an acute opening angle -t with the longitudinal axis 27 of the floor, which preferably does not exceed a value of 20 °.
  • the surface 25 encloses an angle with a surface perpendicular to the longitudinal axis 27 of the projectile, the value of which should preferably be between 40 ° and 50 °.
  • the rear end Piece 22 of the seal 14, which carries the step 15, is also bordered by a spherical surface 28.
  • FIG. 3 shows the cartridge cover 23 in a longitudinal section
  • FIG. 4 shows the cartridge cover 23 in a top view.
  • the radially inwardly projecting part 18 of the cartridge cover 23 which is caused by the bulb-like bending of the cartridge cover material, is appropriately slotted , in such a way that slots 30 are arranged evenly distributed over the circumference of the part 18.
  • slots 30 are arranged evenly distributed over the circumference of the part 18. It has proven to be particularly expedient, as shown in the exemplary embodiment in FIG. 4, to provide four slots 30, which are each 90 ° apart. Starting from the end piece of part 18, the slots 30 are introduced into the part 18 in such a way that they reach at most up to half of the part 18. In this way it is ensured that the part 18 has sufficiently good spring properties and, on the other hand, sufficient strength.
  • the snap connection according to the invention alone can produce a permanent connection between the propellant charge sleeve and the projectile, which meets all requirements.
  • the latching connection can additionally be reinforced with an adhesive.
  • the surfaces of the seal 14 or the part 18 of the propellant charge sleeve 23 intended for connection are coated with a suitable adhesive which hardens after the snap connection has been made.
  • the ballast weight is advantageously reduced in the solution according to the invention by eliminating screws which were necessary in conventional connections between the propellant charge sleeve and the projectile.
  • the increase in the ratio of useful to ballast weight has a particularly advantageous effect on KE ammunition.
