Definitions

  • the invention can be used primarily in the field of large-caliber weapon systems, such as battle tanks and artillery guns, in which Chen the weapon is operated with split ammunition, ie consisting of the ammunition to be fired and a separate, ignitable propellant charge to accelerate the ammunition. But the invention can also be used, for example, in the production and / or handling of propellant charges. In contrast to cartridged ammunition, split ammunition offers the option of varying the amount of propellant charge if necessary, for example to adjust the firing range and thus to be able to fire at targets that are further away or closer.
  • the nested propellant charge modules can be placed on an edge, for example, and the propellant charge module to be isolated can then be subjected to a force from above, whereby the connector between the propellant charge modules is to be released by kinking.
  • the individual propellant charge modules usually consist of a thin outer skin, usually a flammable material, which can easily be damaged if the propellant charge modules are not properly plugged together or separated. Since the propellant charge modules are also often very tightly plugged into one another due to manufacturing tolerances, manual separation can lead to undesired damage to the outer skin of the propellant charge modules, which may mean that they can no longer be used. In order to avoid such problems, devices are known with de NEN the propellant charges in propellant charge modules can be ver individually in individual portions.
