Continuous Rod Warhead Patents (Class 102/474)
  • Publication number: 20080141891
    Abstract: A method for reducing the amount of ammunition types to be used against a wide set of targets. At least two explosive charges are made use of in cooperation. Each of the explosive charges has changeable characteristics and is arranged to mutually cooperate in different ways depending on the particular changeable characteristics given to the explosive charges in a specific case and the type of target to be combated. An ammunition device admitting a reduction of the amount of ammunition types to be used. At least two cooperating explosive charges are arranged in a row along the direction of movement of the ammunition device when activated. Each of the explosive charges is switchable between at least two operating conditions having different operating characteristics.

  • Patent number: 7284490
    Abstract: Rod warhead systems and associated methods are disclosed. In one embodiment, a projectile having an arrangement of rods is propelled along a trajectory toward an object. The arrangement of rods is radially expanded from a first position to a second position prior to the projectile impacting the object. The arrangement of rods impacts the object to breach at least a portion of the object. In a further embodiment, the arrangement of rods is expanded from the first position to the second position using a nonexplosive means. In another embodiment, the projectile includes a follow-up explosive device that applies an explosive force proximate to the object after the arrangement of rods impacts the object.

  • Patent number: 6681679
    Abstract: The invention relates to a wall (2)-protection device (1), notably for a vehicle wall, against attack by a projectile. This device comprises at least one explosive charge (3) able to project at least one metallic block (7) in the direction of the projectile. The device is characterized in that the block or blocks (7) are in the shape of elongated bars, that is which have a maximal length greater than or equal to 10 times their smallest crosswise dimension, the explosive charge (3) being position opposite a longitudinal surface of the bar (7).

  • Patent number: 6279482
    Abstract: There is provided a countermeasure defense system against hostile missiles by employing non-explosive intercepting (“NEI”) elements 14 deployed by the spin stabilized rocket 10. The NEI are carried in a payload section 17 and contained by a sleeve assembly 16 which is removed by a drive mechanism 20 or a pyrotechnic device 152 after a countdown time delay programmed into the trigger release assembly 46 as controlled by the control unit 150. The drive assembly includes a drive rod 26 that is releasably held by a release assembly 46 a compressed coiled spring unit 30 drives the sleeve assembly 16 forward exposing the payload section 17 to the centrifugal force of the spin stabilized rocket propelling the NEI elements out from the rocket at constant angular velocity creating an interceptor cloud of elements.

  • Patent number: 5408932
    Abstract: An elongated rod made of a shape memory alloy composition having selected eudoelastic properties, is deformed into a dimensionally compact coil for packaged storage under stress maintained by physical constraint. Upon selective removal of the constraint allowing shape recovery, a substantial increase in axial length of the rod occurs in order to improve its performance in various installations, including long rod penetrating projectiles.

  • Patent number: 4459915
    Abstract: A solid fuel rocket in which the rocket casing acts as a warhead. Solid propellant rocket motors require relatively heavy cases to contain the 1000-2000 psi combustion pressure needed for efficient performance. This casing can be used as a fragmentation warhead by forming longitudinal grooves in the elongated rocket casing, causing the casing to fracture along the grooves and allowing the pressure within the casing to disperse the fragments. The resulting strip-like fragments are particularly useful against "soft" equipment targets, such as anti-vehicle and anti-radar applications. Several different methods for rupturing the case along spaced, parallel longitudinal lines are disclosed. This system eliminates the need for a separate warhead including case and explosive at the cost of a slight increase in propellant case thickness and weight.

  • 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: H1367
    Abstract: A wire assault weapon warhead preferably for breaching barbed-wire barrics in a battlefield at standoff distances, has a cylindrical shaped projectile having a domed nose cone and a rear bulkhead sized so as to allow the warhead to be fired from a Shoulder-Fired Multi-Purpose Assault Weapon or a similar weapon. The warhead includes a fragmentation tube that fragments upon the detonation of an explosive charge and the fragments expelled into the wire of the barricade sever the wire and breach the barricade.
