  • Publication number: 20180100725
    Abstract: A smoke munition or smoke grenade which can be fired from a launcher, for example a grenade launcher, and has at least one active charge for producing smoke as a protection for ships. To achieve the effect that the active charge of the smoke grenade can be delivered quickly and safely for the ship's crew and the active compound thereof can be converted completely into smoke even after hitting the water, the invention proposes providing the active charge with a floating aid, which can be deployed before the active charge hits the water and prevents the active charge from sinking and prevents the active compound that produces the smoke from becoming wet.

  • Publication number: 20180023928
    Abstract: A method and a device for providing a dummy target via decoy chaffs for protecting a vehicle and/or an object from radar-guided missiles. After identification of the radar-guided missile and calculation of a decoy chaff pattern, the decoy chaff pattern is presented in the form of polar coordinates in accordance with the firing of shots, a “cut-off” distance for the determination of a defence radius is then found in these polar coordinates. A minimum distance between the disassembly or detonation points within the defence radius is set. The dummy target is then optimized on the basis of the “cut-off” distance and the minimum distance between the disassembly or detonation points. As a result of this calculation, the only decoy chaffs that are deloyed are those that meet the conditions, i.e. that have a minimum distance between the disassembly or detonation points within the defence radius in the optimized dummy target.

  • Publication number: 20170299361
    Abstract: A cartridge with a drive system and a projectile which is connected to the drive system, wherein the drive system has a propellant case filled with a propellant and has a case bottom containing a substantially axially extending case bottom opening with a T-shaped edge contour. The case bottom opening is closed by a plug which is of T-shaped configuration, receives an ignition cap and is held in position by a safety fuse ring of a rupture disc. The safety fuse ring is arranged between the front side of the head part of the plug and the rear side of an adjoining inner-side projection of the case bottom, with the result that the propellant chamber is delimited by the front surface of the plug neck. An inner edge of the safety fuse ring engages in a positively locking and/or non-positive manner into an outer groove-shaped recess of the plug.

  • 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: 9121667
    Abstract: A mortar includes at least one barrel mounted movably over a ball journal in a bottom supporting device, and an aiming device serving to aim the barrel vertically and horizontally. In order to be able to aim the barrel of the mortar automatically in a simple and cost advantageous manner, the aiming device preferably comprises a carriage that can be moved along guideways essentially horizontally towards or away from the barrel. At the carriage, the first end region of a pivoted arm is mounted so that it can be rotated about a pivot axis, and the second end region of the pivoted arm is connected with a spherical plain bearing, guiding the barrel. The spherical plain bearing embraces a housing part, which is open at its end faces and in which an inner part is mounted spherically (rotatably), which contains a cylindrical barrel guide, for movably accommodating the barrel.

  • Patent number: 9016205
    Abstract: An irritation body (100, 100?) is proposed, which is formed by at least two modules (101, 102). The upper module (101) serves for acceptance of an ignition head (1) with tilt lever (3) and comprises upper blow-out apertures (8, 9). The lower module (102) is intended for acceptance of an effect-charge (11) with the effect-charge (11) being integrated in a central chamber (10) of a module (102). The chamber (10) itself is functionally connected with the upper blow-out apertures (8, 9) and also with the lower blow-out apertures (12, 18, 19, 20) in the lower module (102).

  • Publication number: 20140352565
    Abstract: An activation unit for explosive masses or explosive bodies includes an ejector tube and high-performance heating elements mounted around the ejector tube, each made of at least one heating wire supplied with electrical power by a control unit. Each heating wire is enclosed in a casing and embedded in a material minimizing heat loss. When the explosive body is passed through the activation unit, the jacket surface of the explosive body contacts the individual elements of the activation unit in a direct or non-contact manner. Thermal energy is transferred to the explosive body by means of the heating wires, and the body ignites at the contact points. A further activation unit includes heating elements in the ejector tube, at least partially fed longitudinally through the ejector tube, made of heating wire clad with CrNi steel and contact plates soldered thereto.

  • Patent number: 8800450
    Abstract: A shell with a subcaliber penetrator, which has a conical tailpiece, and with a basically disk-shaped propulsion element, wherein the conical tailpiece has a frustum-shaped recess that is open towards the rear end. The propulsion element is joined with the penetrator, preferably by a screw connection (projectile fastening bolt). To this end, a bolt element joins the propulsion element and the penetrator in the area of the tailpiece and has a borehole that is open at the rear end, into which propellant charge gases flow when the shell is fired and cause rending of the bolt element and thus separation of the propulsion element from the penetrator.
