  • Patent number: 8776690
    Abstract: The invention relates to a combustible sleeve for accommodating propellant charge powder, to munitions designed using such a sleeve, and to a production method for such sleeves. The sleeve according to the invention is designed for accommodating propellant charge powder and has a jacket wall made of combustible felted fibrous material and an inlay of intersecting threads in the jacket wall. The threads are disposed therein at a distance from one another such that felted fibrous material reaches through the regions between the threads. The method comprises the following steps: preparing a jacket wall made of combustible felted fibrous material and inserting an inlay made of intersecting threads into the jacket wall. The threads are disposed therein at a distance from one another such that the felted fibrous material extends through the regions between the threads.

  • Publication number: 20120132098
    Abstract: The invention relates to a combustible sleeve for accomodating propellant charge powder, to munitions designed using such a sleeve, and to a production method for such sleeves. The sleeve (6) according to the invention is designed for accomodating propellant charge powder (4) and has a jacket wall made of combustible felted fibrous material (23) and an inlay (5) of intersecting threads (5) in the jacket wall. The threads (5) are displayed therein at a distance from one another such that felted fibrous material (23) reaches through the regions between the threads (5). The method comprises the following steps: preparing a jacket wall made of combustible felted fibrous material (23) and inserting an inlay (5) made of intersecting threads (5) into the jacket wall. The threads (5) are disposed therein at a distance from one another such that the felted fibrous material (23) extends through the regions between the threads (5).

  • Patent number: 7707940
    Abstract: The invention relates to a connecting mechanism for a multiple-part munition (1), for example for artillery charges. It is proposed that a multiple-part munition (1) be connected by means of a simple plug connection to at least two casing elements (2) which can be connected to one another and are arranged axially one behind the other, of a propellent-charge casing (10), with the casing elements (2) having a taper (3) and/or a corresponding opening (4) on their mutually facing end faces or tail faces, and the tapers (3) and/or the inner wall (7) of the openings (4) having projections (8) so that they can be connected to one another with a force fit by pushing them together.
