  • Patent number: 4936217

  • Patent number: 4922826
    Abstract: An active component of submunition for utilization from a carrier against different target objects, especially against semi-hard and hard or heavily armored target objects; as well as warheads for this purpose and flechettes which are preferably deployed over the targets through the intermediary of such warheads. The active component incorporates at least one warhead having flechettes, which is equipped with a propellant or propulsion mechanism for the acceleration of the warhead in the direction of effect for the flechettes, and with an ejector piston for additional acceleration of the flechettes through the ejection from the precedingly accelerated warhead.

  • Patent number: 4917016
    Abstract: A warhead casing containing an explosive charge for the formation of projectiles, and in which the casing has portions with notches formed therein to facilitate the formation of splinters or fragments in addition to the projectiles. The notches may be formed in the outside surface, inside surface or both inside and outside surfaces of the casing to provide splinters of specific sizes and shapes optimized for the attacking of specific types of targets.

  • Patent number: 4458594
    Abstract: In small-caliber, barreled-weapon ammunition with head or base fuses, detonator safety is achieved in that the inadvertantly ignited detonator which is a secure position within a rotor remains without effect on an intensifying charge. Measures are provided for the gas to expand within the fuse and the energy of the rotor fragments used up so that the gas expanding direction and the flight direction of the fragments face away from the explosives of the intensifying charge. Expansion chambers are formed by recesses in the fuse for safety devices adjacent the rotor, such as different centrifugal force-dependent safety devices for the firing pin which are separated from each other by breaking locations destroyable by the gas.

  • Patent number: 4362563
    Abstract: A process for producing a formed member, and a formed member which includes spherical fragments embedded in a metallic matrix is effected through cold pressure rolling. The spheres are arranged in the interspace between a basic support member, which may be a thin-walled inner casing, and an outer casing. Forging of the outer casing causes the material of the support member and the outer casing to be pressed into the spaces between the spheres, densifies the support member and the outer casing, and prestresses the outer casing and spheres, thus allowing the inner casing to be extremely thin-walled. The prestressing of the spheres and outer casing, together with the inner casing imparts a high degree of energy to the casing fragments and to the spheres, affords economies in manufacture and a substantial increase in fragmenting energy at detonation of the formed member.

  • Patent number: 4296180
    Abstract: A process for producing a formed member, and a formed member which includes spherical fragments embedded in a metallic matrix is effected through round cold forging. The spheres are arranged in the interspace between a basic support member, which may be a thinwalled inner casing, and an outer casing. Forging of the outer casing causes the material of the support member and the outer casing to be pressed into the spaces between the spheres, densifies the support member and the outer casing, and prestresses the outer casing and spheres, thus allowing the inner casing to be extremely thinwalled. The prestressing of the spheres and outer casing, together with the inner casing imparts a high degree of energy to the casing fragments and to the spheres, affords economies in manufacture and a substantial increase in fragmenting energy at detonation of the formed member.

  • Patent number: 4292829
    Abstract: A process for producing a formed member, and a formed member which includes spherical fragments embedded in a metallic matrix is effected through cold annular or round forming. The spheres are arranged in the interspace between a basic support member, which may be a thin-walled inner casing, and an outer casing. Working of the outer casing causes the material of the support member and the outer casing to be pressed into the spaces between the spheres, densifies the support member and the outer casing, and prestresses the outer casing and spheres, thus allowing the inner casing to be extremely thin-walled. The prestressing of the spheres and outer casing, together with the inner casing imparts a high degree of energy to the casing fragments and to the spheres, affords economies in manufacture and a substantial increase in fragmenting energy at detonation of the formed member.

  • Patent number: 4281599
    Abstract: A projectile including a penetrating member and a pyrotechnic composition, such as an incendiary composition. The composition is located ahead of the head portion of the penetrating member and is surrounded by a ballistic hood. The projectile includes a solid insert of a pyrophorically acting metal or an alloy containing such a metal. In order to increase the effect of the projectile, the pyrometal insert is located in a recess provided in the head portion of the penetrating member. Furthermore, arranged in a rearward extension of the recess and immediately behind the pyrometal insert is, additionally, an explosive material insert adapted to be detonated at impact against a target.

  • Patent number: 4280408
    Abstract: A projectile with a penetrating member, in which a pyrotechnic composition is arranged ahead of and rearwardly of the penetrating member. The forward composition, preferably incendiary, is encompassed by a ballistic hood, the rearward composition being at least partially of explosive material is detonatable by an impact detonator. The head portion of the penetrating member is formed of two regions having different slopes to increase the activity of the projectile at flat striking angles against a target. The two regions are separated by a sharp-edged gripping edge. The penetrating member may also include in the interior thereof a plug of a pyrophorically acting metal or alloy.
