Definitions

  • the present invention relates to a training cartridge for recoil-free defense weapons, such as the apelooka. It is based on a state of the art, as described for example in DE-AS 20 59 202. According to this, such a practice cartridge consists of a propellant charge sleeve for accommodating a propellant charge and a sub-caliber projectile which is fired from a sub-caliber barrel accommodated in a dummy storey, the dummy projectile being inserted into the barrel muzzle with its hollow shaft coaxially surrounding the sub-caliber barrel and by means of an ejection of the dummy projectile effecting and the firing bang simulating ejection charge is provided, which is accommodated in an ejection charge sleeve connected to the bottom of the propellant charge sleeve and guided in the barrel and the powder charge of which is ignited laterally through the sleeve wall in the region of an annular groove-shaped cross-sectional weakening which allows the ignition beam to pass through and the ignition
  • a disadvantage of conventional practice cartridges is that they have unsatisfactory flight behavior and sometimes even hit the target in a transverse position, ie. H. spin and that after the practice shooting non-rotting material from the dam remains on the floor (plastic) or that moisture is introduced during assembly, which affects storage stability (cardboard disks).
  • the present invention has therefore set itself the task of creating a cost-effective practice cartridge with improved flight characteristics of the projectile and thus increased hit accuracy and further by using a certain material for the insulation on the one hand rotten and at the same time space-saving and storage-stable.
  • a practice cartridge for recoil-free defense weapons consisting of a high-weight projectile head housed in a cartridge case, preferably with a disassembly core and a tail unit, as well as loading and unloading, characterized in that the projectile head has a step on the end face and that between the projectile head and the tail unit there is a tail unit Tapered intermediate piece is arranged, wherein the intermediate piece and tail unit are made of light material such as plastic or preferably aluminum and that the tail unit is of the same caliber.
  • the empennage itself is guided in the cartridge case, preferably in a sliding fit, which enables a precise launch that is free of tilting moment until it emerges from the case.
  • the front step of the projectile head can be a flat surface, but this requires a relatively high face resistance. It is therefore still proposed to arrange a cone centrally at this level, whose foot diameter is smaller than that of the projectile head, so that an outer ring is formed around it.
  • the cone itself is preferably also truncated.
  • the tail unit like the intermediate piece, is particularly advantageous, i.e. H. inexpensively made of extruded aluminum or similar ductile material or of plastic.
  • the projectile is preferably constructed in three parts and consists of the projectile head which can be solid or hollow and filled with metal powder or ceramic powder and an intermediate piece which tapers towards the tail unit, all parts being screwed together.
  • the tail unit has a backward-open bowl to accommodate the tracer. If the tail unit is designed as a plastic part, it may be necessary to place it in a metal insert.
  • a construction has proven to be particularly flight-stable and accurate, in which the width of the ring surface is approximately 0.1 to 0.2 times the length of the projectile and 3.8 to 5.2 times the projectile Head diameter or caliber, the mass of the projectile head makes up about 84 to 94% of the total weight and its length or the length of the fragmentation charge 40-60% of the total length.
  • the tail fins preferably have outer, axially parallel edges, which abut the inner wall of the cartridge and guide the projectile as it exits.
  • the number of fins increases the accuracy of guidance.
  • a certain opening of the fins between one another is also necessary for a perfect flow.
  • An eight-tail empennage has proven particularly useful for conventional apelooka practice ammunition.
  • the insulation further consists of iron powder or preferably of pressed or sintered metal, preferably iron powder.
  • Metal powder such as preferably iron powder
  • Metal powder has significant advantages over plastic granules or cardboard disks. Firstly, because of the higher specific weight, it is possible to reduce the dimensions. On the other hand, fine iron powder rots well.
  • the metal powders can preferably be entered as pressed bodies or sintered materials, on the one hand they have a very small surface area and thus introduce little adsorptive water, they can additionally be provided with a lacquer coating and thus considerably increase the storage stability.
  • Another improvement of the practice cartridge is the separation of the Deut charge into a front one made of black powder and a rear one made of nitrocellulose powder, both of which are separated from each other by a suitable disc.
  • a suitable disc In connection with the formation of the propellant charge from nitroglycerin powder, u. a. low residue combustion with improved firing behavior.
  • the propellant charge is fired through an ignition channel, which is arranged in the cartridge case.
  • Fig. 1 shows the practice cartridge with the projectile. This consists of the projectile head 2, the tapering intermediate piece 11 and the tail assembly 4 connected to it.
  • the projectile is mounted in the cartridge case 1 and guided through the tail edges 8 in the inner wall of the case.
  • the sleeve holds the projectile in the clamp seat 12, in which the cartridge case 1 is folded over at right angles at the screwing point between the projectile head 2 and the intermediate piece 11 and is clamped by screwing parts 2 and 11 together.
  • the tail unit encounters a eyelid cap 13 which has a central bore for igniting the tracer in the interior of the tail unit carrier 14.
  • the propellant charge 15 is located below the eyelid cap in a corresponding recess in the cartridge case 1.
  • the cartridge case 1 is screwed to the Deutladungshülse 16 connecting to the rear.
  • the front Deutchar 18 is to which the rear Deutchar 19 and the dam 5 connect.
  • This insulation consists of iron powder compacted by sintering or pressing in the form of disks, which are pulverized when ejected and cool the escaping flame due to their large surface area and their specific heat and, on the other hand, are abruptly braked due to their small grain size. Ultimately, iron powder rots relatively quickly.
  • the compacts of the dam 5 have the shape of perforated disks.
  • the propellant charge 15 consists of nitroglycerin powder and is covered on both sides by plastic discs glued with tissue paper.
  • the front Deut cargo 18 made of nitrocellulose powder.
  • the ignition channel is designated by 21.
  • Fig. 2 shows the floor in plan view and in section with two versions of the stage according to the invention.
  • the projectile head 2 can be solid or can be filled with a pulverized charge 3.
  • the hollow body 20 can also be made of plastic, e.g. B. Ultramid exist.
  • the truncated cone 9 connects, creating an annular surface 10, the width of z. B. can be about a third of the total projected area, the outer diameter is z. B. 18 mm and the diameter of the conical foot 13 mm.
  • the projectile head 2 is screwed to the adjoining tapered intermediate piece 11.
  • this is preferably made of metal (aluminum).
  • the tail boom 14 is in turn screwed to the intermediate piece 11. This is cylindrical and carries the tail fins 4 with the guide edges 8.
  • This type of room shape enables easy manufacture of the entire tail unit from e.g. B. extruded aluminum or a production as a cast or injection molded part, also made of plastic.
  • the projectile head 2 can also be designed in a simple manner to be completely flat with a cylindrical surface 21, the flight stability being retained, but the face resistance increasing.
  • the tracer 22 is located inside the tail boom 14.
