Abstract: A method and device for judging the aiming error of a weapon system and a use of the device are disclosed. The weapon system includes a fire control device (F) for tracking a target (Z), a weapon (W) having a weapon barrel (B), aiming means for aiming the weapon barrel (B), and a data processing facility (EDV). The fire control device (F) continuously tracks the target (Z). An image recording device (V) moved in solidarity with the weapon barrel (B) record images of the target (Z) and its surroundings. An image reproduction device (M) displays the images recorded by the image recording device (V) and a mark (X). The mark (X) represents an aiming line, a deviation (a) of the target (Z) from the mark (X) representing the aiming error of the weapon system. The fire control device (F) performs the aiming of the weapon barrel (B) on the basis of a lead calculation, which takes the movement of the target (Z) into consideration. The device may be used for fixed and mobile weapon systems.
Abstract: The projectile attachments to a forced air compression chamber are devices that are attached to force air compression chambers and permit the user to place the projectile in or on the launch chamber prior to operating the air compression chamber thus making for a more fluid movement. The flexible ball projectile attachment allows the user to place one or more balls into the launch chamber and eject the same in a fluid movement without the aid of mechanical devices. Thus increasing the reliability and decreasing the number of moving parts in the typical ball launching device. The flexible dart type projectile attachment allows the user to place the dart type projection on the launch chamber and then suck air into the air compression chamber through the non-tube openings and when air is expelled from the air compression chamber the flexible diaphragm closes over the non-tube holes thus ejecting the dart type projectiles. Thus making the use of the launch chamber more efficient and easier.
Abstract: A high-precision pyrotechnic initiator is well adapted for rapid, precise ignition of solid and liquid energetics. A rigid housing, for example formed of an SiC-treated semiconductor substrate material, contains a pyrotechnic. When ignited, the reaction, or explosion, of the pyrotechnic is confined to the housing. The release of energy creates a hot particulate in which the formation of solid byproducts is mitigated or eliminated. The flame is directed through an outlet. In one embodiment, a microcapillary tube may be placed in communication with the outlet, the tube including a primary front vent and secondary side vents, which serve to increase system efficiency and reliability. A dual bridge wire may be provided for improving system reliability. The resulting assembly thereby performs the combined functions of both an igniter and a flash tube and a complete ignition train is provided in a manner that overcomes the limitations of the conventional configurations.
Abstract: A frangible projectile for gun ammunition wherein the projectile includes a core formed from one or more metal powders which are pressed into a self-supporting compact and incorporated into a metal jacket. The metal jacket is initially cup-shaped (generally cylindrical in overall geometry) with an open end and a closed end. In accordance with one embodiment of the present invention the closed end of the jacket becomes the trailing end of the projectile. In another embodiment, the closed end of the jacket becomes the leading end of the projectile. In either embodiment, that surface of the closed end of the jacket which faces inwardly of the volume of the jacket is indented and stressed over substantially its entire area in accordance with a pattern which enhances the frangibility of this closed end of the projectile when the projectile strikes a target.

Abstract: A cartridge with a propellant case (4) that contains a propellant charge (3) and an electrothermal ignition device, wherein several ignition channels (9) are provided in the charge (3), and extend axial-symmetrical in the direction of longitudinal axis (8) of cartridge (1), with each channel comprising a propellant tube (10) and an electrically conducting layer (11). To achieve a uniform and symmetrical ignition of the cartridge (1) in the chamber of the respective weapon, electric arcs (21) that form during the ignition operation in the ignition channels (9), are decoupled in that the electrically conducting layer (11) is composed of successively connected rhombi or other shapes (circles, ovals, etc.) that electrically function as decoupling resistances. When current flows through such a structure, the current bridges (20) arranged in the current-flow direction between the individual rhombi (15) etc. initially break apart explosively.
Abstract: A specialty bullet is disclosed that is adapted to transmit a tranquilizing fluid upon impact with a target for purposes of immobilizing the intended target without causing great harm to the target or the surrounding area. The specialty bullet is sized and shaped like that of a conventional bullet so that it can be fired from a conventional firearm; however, the concept could work with innumerable types of ammunition. The disclosed invention includes a so-called “Collapsule” bullet, which is a molded, hollow cavity fabricated of a high-strength malleable plastic polymer that is filled with a tranquilizing fluid. The bullet is fitted with a so-called “Injectile,” which is a hypodermic injection spike (to transmit the tranquilizing fluid) that is backed and driven by an inertia base mass (i.e., lead core or other suitable) located at the base of the bullet.

Abstract: A method of manufacturing a soft point bullet and the bullet resulting there from. The method comprises forming a bullet core of a first material plated with a second material; providing a cavity in one end of the plated core of preferably polygonal shape and positioning a shaped blank of plating material into the cavity; and forming the core into the final bullet size and shape by extruding the core into the cavity to form the bullet nose and encapsulate the shaped blank within the bullet.
Abstract: A method and apparatus for placement of continuous pre-split, gel explosive in an elongated borehole or cavity. An anchor is attached to one end of a selected length of continuous gel explosive. A suitable anchor is a flexible, plastic “pilgrim's hat” with a hole in the narrow, closed end. The size of the anchor depends on the width of the borehole; the flared skirt should be narrow enough to permit insertion of the anchor into the hole but wide enough to resist removal. One end of the explosive charge is pressed through the hole in the anchor. The remainder of the length of explosive is placed inside a tubular member, such as PVC pipe. The loaded pipe then is inserted into the borehole or cavity with the anchor leading. The pipe is used to push the anchor back into the hole to the desired depth. Then, the pipe is withdrawn. The flexible skirt on the anchor engages the sidewall of the borehole and thus resists removal with the pipe.
Abstract: An device for correcting the in-flight trajectory of a munition consists of an impulse motor assembly body. The slug or multiple slugs and propellant(s) are located within the impulse motor assembly body. When a trajectory correction is desired and required, the individual impulse motor propellants are activated and fired, and the slug or multiple slugs are propelled out of the in-flight munition at a specific time and a specific angle on or near the gravimetric center of gravity of the in-flight munition. The reactive forces created by the explosion of the(se) heavy metal slugs does, by equal and opposite reaction, create a corrective vector and thereby does cause a correction in the trajectory of the in-flight munition.

Abstract: A munition in the form of a projectile contains a dart having a body terminating in a front tip and ductile hammer block in the form of a ferrule engaging at least a part of the dart. The dart is formed of sections the diameters of which increase from the back to the front of the dart body, forming support shoulders. A recess in the hammer block has a shape corresponding to the dart body shape received in the hammer block. Hammer block sections form thrust shoulders which engage the corresponding dart support shoulders. When the projectile impacts a target, the thrust shoulders push against the dart support shoulders, causing the ductile hammer block to open and flare out.
