  • Patent number: 8250988
    Abstract: The invention relates to a subcaliber projectile, particularly for a dart projectile, having a resistance-stabilizing, conically designed guide mechanism having a frustum-shaped recess, wherein a guide cage has a substantially hollow cylindrical design in which a propulsion element is integrated therein on a rear side. To allow the propulsion element to be produced in a simple fashion and the guide cage to be lighter weight than comparable known drive cages, the propulsion element is designed substantially only as a disk-shaped metal plate extending transverse to the longitudinal axis of the guide cage, wherein the drive element is mounted on an edge in an annular groove-shaped recess of the inner wall of the guide cage, wherein the disk-shaped metal plate comprises a central through hole, the diameter of which is as large as possible, but smaller than the maximum diameter of the frustum-shaped recess of the guide mechanism.

  • Patent number: 8225999
    Abstract: The aim of the invention is to devise an inexpensive method and device that allows predefined target tolerances of an automatic weapon (1) to be maintained even in the range of prevailing resonant cadences. This aim is achieved by modifying the actual cadence of the automatic weapon from shot to shot around a predefined cadence lying within the range of a resonant cadence so that the time interval between successively triggered shots is alternately shorter and longer than the calculated constant time interval between the individual triggered shots that is calculated for the predefined cadence and that corresponds to the constant time interval required to fire the automatic weapon at the predefined cadence. In this way, the automatic weapon is controlled to fire at a time averaged cadence that is equal to the desired predefined cadence while avoiding ever actually firing the automatic weapon, shot-by-shot, at the resonant cadence.

  • Patent number: 8223061
    Abstract: The invention proposes to provide distraction spoofing even on modern infrared, radar and dual-mode guided missiles (4) by production of a decoy chain (20). The chain (20) is formed by a plurality of apparent targets which are switched successively, for example by firing of individual chaff submunitions (2.1-2.5). The deployment takes place before or during the search phase of the missile and can in this case, for example, be carried out using the reverse walk-off principle or at the same time simultaneously or successively and in the form of a pattern. This ensures that the decoys (2.1-2.5) act initially in the greatest selected range zone away from the target (3). The spoofing chain (20) created in this way results in the missile (4) having to carry out a series of time-consuming analysis processes on its way to the target (3).

  • Publication number: 20120132061
    Abstract: A mechanism or drive (100) for a weapon is described, which is characterized by only a limited acceleration of the breech (20) and a jerk- and recoil-free operation, thereby reducing the inertia force and the required power and increasing the repetition rate. The reduction of the required power also results in a reduction of braking power in the case of a quick stop. For this purpose, the rotational motion of preferably a motor (50) or the like is converted to a forward or reverse motion of the breech (20) using the Scotch yoke principle. In order to allow rest periods of the breech in the end limit positions, the rod (3) and the yoke (1) are arranged radially and displaceable relative to each other so that the yoke radius changes when the yoke (1) is rotated. A control cam (6) radially guides the rod (3).

  • Patent number: 8099893
    Abstract: In a first step, it is proposed that tunable transmitters and detectors (receivers) be included in a detection system and that a narrowband, preferably variable frequency signal be used in order to determine the frequencies for optimum injection into the electronics of a target. When the detection system identifies these frequencies, destruction can be initiated in the second step of the invention for a transmitter or receiver which is communicating with the target. For this purpose, once the optimum frequencies have been determined, a high-power signal is transmitted into the local area of the target at the specific/determined frequency. The evaluation unit, which is integrated in the detection system, controls the transmission frequencies, evaluates the harmonic signals, selects the optimum frequencies for an attack, and controls and checks the attack process.
