  • Patent number: 6119600
    Abstract: By means of this method it is possible to produce projectiles with single- or multi-element projectile bodies of different shapes and sizes simply and in a time-saving way. The jacket (1) of the projectile consists of a projectile tip (3), which is fixedly connected with a projectile casing (2) and has a centering device (5, 9) in its interior, in which the projectile body (6) is guided and maintained. The projectile body (6) is essentially cylindrical or has a diameter which increases toward the rear. The back of the projectile casing (2) is closed by means of a sealing body (15), which partially extends around the projectile body (6). In the course of producing the projectile, the projectile tip (3) is injection-molded to the projectile casing (2) in a first step, and in a second step the projectile body (6) is pushed into the centering device (5, 9).

  • Patent number: 6105505
    Abstract: The present invention is directed to a hard target incendiary projectile that includes a penetrator casing filled with an incendiary and having a rear opening sealed with a closure. When the projectile hits a target and penetrates, a fuze ignites the incendiary. Hot gasses from the burning incendiary increase pressure within the casing so that within milliseconds of the fuze firing, pressure within the casing ejects the closure out of the rear opening with a vigorous pressure pulse that expels burning fragments of incendiary into the interior of the target. The projectile can also carry additional payloads such as chemicals, radioactive materials, and electric/electronic devices that can be ejected from within the casing into the target. The projectile can also be configured so that pressure within the casing opens vents in the closure but does not eject the closure. As the incendiary combusts or reacts within the casing, hot reaction products are vented through the vents into the target.

  • Patent number: 5880398
    Abstract: A dual-purpose bullet is provided consisting of a thermoplastic body, a base cap, and a pressed powder core. The bullet in the preferred embodiment can either penetrate destroying and disrupting large volumes of human tissue or not penetrate the human tissue delivering a strong shock event and creating a thermal nuisance. The lethal mode is achieved by a high-velocity launch of the bullet without ignition of the igniter mixture and pressed powder core. The less-than-lethal mode is achieved by a low-velocity launch with ignition of first the pressed powder core and softening of the plastic projectile body.

  • Patent number: 5728968
    Abstract: An armor penetrator projectile is disclosed that has an elongated rod penetrator core. The core has a central bore therein extending from a rear portion to a front end portion of the core. The front end portion is preferably conically shaped for impact with an armor plate. A self igniting pyrotechnic material such as thermite is packed within the rear portion and in the bore. The thermite is ignited by the frictional heat and pressure generated during projectile impact with a target armor plate. The ignited thermite ejects a molten jet of material through the bore and forwardly out through the impacting front end thus further melting the armor plate about the point of impact and enhancing the behind armor destructive effects of the projectile.

  • Patent number: 5109774
    Abstract: Disclosed is a new type of penetrating projectile, the penetrating capacity of which is improved and more efficiently controlled, notably through a solution to the problems of obliquity. A projectile of this type has a front element forming the active part, fixedly joined to a tube. The tube has a closed end which contains a propellant charge for the propulsion of the element and an igniter for the charge, responding to the impact of the element on a target. In reaching the target, the projectile penetrates it slightly under the effect of the velocity and it is only at this instant, or slightly after it, that the penetration proper takes place. The penetration thus takes place without obliquity. This projectile can be used as an individual munition or sub-munition.

  • Patent number: 4505202
    Abstract: A projectile for dispersing a riot control agent material into the atmosphere at a target. The projectile is designed to open in flight and scatter a number of independent dispersal charges over a limited target area, and comprises a sabot in the form of a number of segments which are locked together prior to launching, which contains the dispersal charges and a delayed opening means which initiates opening in flight, thereby releasing the charges along approximately the same trajectory as the former projectile. In a preferred embodiment the sabot is cylindrical, in two segments hinged together at their rear end, locked together by either a collar or a pin and socket arrangement, and containing a number of cylindrical charges in line, with an axial channel. The projectile is fired from a gun, and firing initiates a pyrotechnic delay which activates an explosive or pyrotechnic charge in the channel and between the charges to open the sabot and activate and disperse the charges.
