Definitions

  • the invention relates to a propellant charge case according to the preamble of claim 1.
  • the invention is based on the object of specifying a propellant charge sleeve which is particularly simple to produce and which therefore greatly simplifies and reduces the cost of laboring propellant charges, in particular also of the cartridge ammunition.
  • Fig. 1 shows a schematic representation in a side view of a large-caliber cartridge ammunition 10 with a projectile 12, a sleeve bottom 13 made of metal and a combustible sleeve 11 and a lid made of an elastic material 14.
  • the propellant charge sleeve 11 consists of a combustible plastic film 20, which envelops the propellant charge powder, which is not visible in FIG.
  • the plastic film 20 is particularly advantageously designed as a shrink film, which shrinks considerably under the influence of heat, thereby compressing the encased propellant powder strongly and in this way ensures excellent mechanical strength of the propellant charge build-up. Compared to a loosely filled powder, this also enables a significantly higher loading density to be achieved, which brings internal ballistic advantages.
  • a method known per se in the field of food packaging is used, in that after the
  • Propellant powder with the film 20 is sucked air by connecting a vacuum pump. This also causes the film 20 to lie closely against the enveloped propellant charge powder, which results in a structure which is similarly stable as when using a shrink film.
  • the propellant charge sleeve 11 is expediently introduced into a mold, on the inner wall of which it is supported during the filling process.
  • a higher charge density can be achieved, combined with an improvement in the mechanical stability of the propellant charge build-up.
  • Plastic films which are set to a desired burn-off behavior by oxygen carriers are particularly suitable.
  • plastic films made of polyethylene, polyurethane, polyisobutylene, polybutadiene and polysulfides are suitable.
  • Combined oxygen carriers such as boron / potassium nitrate, zirconium / barium nitrate and mixtures of the metals magnesium, boron and aluminum with the oxidizers mentioned above are also particularly suitable for the propellant charge sleeve.
  • the stability of the propellant charge sleeve can be increased further by covering the plastic film 20 with an outer coating 21 'made of polyurethane, as the cross-sectional image of a propellant charge sleeve 11 shown in FIG. 3 shows.
  • this is expediently mixed with a mixture of e.g. B. boron potassium nitrate or other aforementioned oxygen carriers.
  • the invention also offers further advantages, since the storage stability of the propellant charges can be increased by selecting gas and moisture-tight film materials.
  • cartridge ammunition (FIG. 1) is used with the foil 20 according to the invention configured propellant charge sleeve 11.
  • the film 20 is in the form of a hose which is fastened on the one hand to the rear of the projectile 12 and on the other hand to the sleeve base 13.
  • These fastenings can preferably be brought about by gluing or welding, possibly also by screwing, spraying or by shrink fit of the film. Possibly. can be attached to the lid 14 simultaneously with the attachment of the film 20 to the sleeve bottom 13.
  • the propellant charge can then be introduced into the propellant charge sleeve 11.
  • Bulk powder can expediently be filled in through the opening provided in the case base 13 for the propellant charge lighter, while tube powder is to be filled into the case 11 before the case base 13 is fastened.
  • the propellant charge sleeve 11 is then shrunk or evacuated. When evacuating, the opening of the propellant lighter can be used to extract the air.
  • the propellant charge sleeve 11 which is completed by shrinking or evacuating, has a highly irregular external shape.
  • this proves to be an advantage from the inside ballistic point of view, since this facilitates the combustion of the film 20.
  • propellant charge 40 of modular construction, in which propellant charge portions 43 are arranged in portions in a shrink tube 42 separated from one another.
  • the propellant charge portions 43 are in turn housed in an outer shell 41, which is also made of plastic film.
  • propellant charges 43 arranged in a shell 41 can be used simultaneously or only partially.
  • the outer shell 41 is designed to be easy to tear open, so that any number of propellant charges 43 that are not required can be removed.
  • the connecting pieces 44 are perforated between the foil casings enveloping the propellant charges 43 and are therefore easily separable.
  • the hose pieces 42 enveloping the propellant charges 43 can expediently be provided with different colors and / or an imprint, e.g. B. be marked with a number.
