  • Publication number: 20240377175
    Abstract: The invention relates to an ignition device for ammunition, in particular medium-caliber ammunition, comprising at least one battery and at least one electric or electronic ignition-chain component, wherein: the battery has a battery housing; an electrolyte and at least two electrodes are located in the battery housing; an explosive charge of the ammunition can be caused to explode by means of the electric or electronic ignition-chain component, and the energy required to trigger the electric or electronic ignition-chain component can be provided by means of the battery. The ignition device provides for a sufficient amount of energy, and the volume in the ignition device is at the same time utilized particularly efficiently in that the battery housing has a cup-shaped recess, and at least part of the at least one electric or electronic ignition-chain component is located in the cup-shaped recess.

  • Patent number: 11307006
    Abstract: The invention relates to a projectile (1, 8, 9) having at least one payload (5) or explosive charge in the projectile body (2, 7, 10), preferably in the medium caliber range, the payload (5) being integrated into the projectile body (2, 7, 10) in the form of a pyrotechnic charge. The payload (5) can preferably be enclosed and sealed by a core (6, 14) which preferably consists of metal or plastic. In an alternative embodiment, the pyrotechnic payload (5) is disposed behind a penetrator (11) in the projectile body (10), the payload (5) thus being located between the penetrator (11) and the projectile body (10).

  • Patent number: 10996035
    Abstract: A fin-stabilized sub-caliber projectile adapted to be fired from a rifled barrel, the projectile having a penetrator with a tail fin assembly, a sabot arranged on the penetrator and having at least two sabot segments circumferentially joined to one another that are separated from one another after leaving the barrel by centrifugal forces acting on the projectile during firing. The sabot includes a main body and a front guide flange that is adapted to be supported on an inner wall of the barrel and a rear guide flange arranged at an axial distance. A connecting section of the sabot is arranged between the front guide flange and the rear guide flange and has a smaller outer diameter than the front guide flange or the rear guide flange. The sabot and the penetrator are joined together in a positive manner in a region of the rear guide flange.

  • Patent number: 9528806
    Abstract: The invention relates to a sabot (4) for a sub-caliber projectile (1) having a projectile core (2). When the projectile exits a weapon barrel, the sabot detaches from the projectile core (2) without transferring momentum by means of a separating aid (4) incorporated between the projectile core (2) and the sabot. The separating aid (4) has a plurality of fingers (5) having at least one predetermined breaking point (8a, 8b), which is connected to the projectile core (2) by a type of snap-connection bead (6) on the fingers/braces (5).

  • Patent number: 9188415
    Abstract: A part of a cover is pressed radially into a circumferential groove contour in a projectile body by a preferably rigid die, which need only be moved axially and which is provided with a special outer contour. An outer contour should be matched to the groove contour or vice versa, so that the material of the cover that is formed radially by the forward-moving die can be pressed into the groove contour of the projectile body, and the cover no longer has any degrees of freedom after the forming, so that it is secured with respect to the tracer or the like. The cover is preferably a cover ring.

  • Patent number: 8518197
    Abstract: Disclosed is an incendiary compound comprising spherical zirconium, titanium, or hafnium powder having an average grain size of 50 to 250 ?m as well as a thermosetting or thermoplastic micronized organic binder which is added to the powder at a quantity of less than 1 percent by weight. The incendiary compound is fastened in the projectile or warhead by pressing and then thermally treating the same in order to activate crosslinking of the thermosetting binder or melt the thermoplastic binder.

  • Publication number: 20110011296
    Abstract: The invention relates to a subprojectile (1) comprising a body, which is provided with a borehole (5) and consists of hard metal or heavy metal, an energy component (3) with or without a firing means (4) being incorporated into the borehole (5). The energy component (3) with or without a pressure-sensitive firing means (4) is fired or activated by air friction, by an ignition in the carrier bullet together with a firing charge, or at the latest when the target is hit.
