  • Publication number: 20140230682
    Abstract: A warhead system, method and apparatus. A warhead includes a liner having a logitundinal axis that runs down the center of the liner. The liner includes a liner pattern and a liner shape. The liner shape is selected and a radial distance from the longitudinal axis is selected. The liner pattern is warped as a function of the selected distance and the shape of the liner to reduce the effects of spoking in the post-detonation fragmentation pattern at the selected distance. The liner is then formed as a function of the warped liner pattern.

  • Patent number: 8746145
    Abstract: A munition is described including a reactive fragment having an energetic material dispersed in a metallic binder material. A method is also described including forming a energetic material; combining the energetic material with a metallic binder material to form a mixture; and shaping the mixture to form a reactive fragment. The munition may be in the form of a warhead, and the reactive fragment may be contained within a casing of the warhead.

  • Patent number: 8689669
    Abstract: The present invention is directed to a method for production preformed fabrication casing or associated parts intended to generate fragments initiated by the explosive of contained warhead charges. Molded parts having fragmentation bodies (4, 21, 34) embedded therein are produced by a two-stage powder compaction method followed by sintering together the compacted powder metal. The method described in the present invention defines how in an initial stage the fragmentation bodies (4, 21, 34) are fixed in position using a fixture (2) after which the bodies are covered with powder metal that is then compacted until the powder forms a single molded part (2) after which the fixture is replaced with a secondary quantity of powder that is also compacted to form a self-supporting unit (12) together with the first quantity of powder.

  • Publication number: 20140020590
    Abstract: The present invention relates to a method for the production preformed fragmentation casing or parts thereof intended to generate fragments initiated by the detonation of the explosive contained in warhead charges where the said casing or parts thereof are of the type that comprise a single-unit moulded part (7, 10 and 25,28) created by sintering powder metal and where the said moulded part contains embedded separately produced fragmentation bodies (4,21, 34). A distinguishing feature as claimed in the present invention is that the moulded part in which the fragmentation bodies (4, 21, 34) are embedded is produced by means of a two-stage powder compaction method followed by sintering together the compacted powder metal.

  • Publication number: 20130255524
    Abstract: A fragmentable projectile casing for an explosive projectile (7) has an irregular wall thickness (W) and predetermined breaking points (2) distributed over the projectile casing (1) for formation of fragments. The predetermined breaking points (2) for obtaining uniform fragments are spaced irregularly from one another. The predetermined breaking points (2) can have a smaller distance from one another in a region of greater wall thickness (W) and can be arranged in the manner of a grid and/or are formed as lines. Further, the predetermined breaking points (2) can run parallel to a longitudinal axis (L) of the projectile casing (1) and/or along a circumference (U) of the projectile casing (1).

  • Patent number: 7597037
    Abstract: A method for geometrically enhancing of the flight of a projectile fired from a weapon to an intended target, including development of a flat annular face on the outermost end of the ogive portion of the projectile, such flat annular face being oriented in a plane that is substantially perpendicular to, and concentric with, the longitudinal centerline of the projectile, and further including extraction of extraneous material from the meplat cavity of the projectile while establishing at least a void volume within the meplat cavity which is substantially concentric with the longitudinal centerline of the projectile and of substantially uniform size and geometry from projectile to projectile. Geometric alteration of the wall thickness of the flat annular face also may be provided. An enhanced projectile and a round of ammunition are disclosed.

  • Patent number: 6874402
    Abstract: A projectile, having a casing, a projectile base, which closes the casing off at the rear, a receiver coil for receiving electromagnetic signals, an energy source which is put into contact with the receiver coil, and a logic module. The casing is made from a plastic material, at least in the area of the rear.

  • Patent number: 6862995
    Abstract: A bean bag (15) installable in a cartridge for use as a less-lethal projectile in striking a target without killing or seriously injuring the target. A doubled-back open-sleeved configuration (27) of the fabric-constructed material includes a compartment in a shorter portion (33) interiorly disposed to a longer portion (36) of the opened-sleeved configuration (27), pellets (23) pre-measured by weight substantially filling the compartment (22). The length (26) of the open-sleeved configuration of the material for the bean bag 15 is determined by weight rather than by its length. The shorter portion (33) and longer portion (36) are fastened together as at (34) thereby determining the size of compartment 22 for the weighted pellets (23).

  • Publication number: 20030140772
    Abstract: The method of making a non-lead hollow point bullet has the steps of a) compressing an unsintered powdered metal composite core into a jacket, b) punching a hollow cavity tip portion into the core, c) seating an insert, the insert having a hollow point tip and a tail protrusion, on top of the core such that the tail protrusion couples with the hollow cavity tip portion, and d) swaging the open tip of the jacket.
