  • Patent number: 9541363
    Abstract: A series of small explosive charges are used to preferentially crack the casing of a warhead to provide for a controlled fragmentation of the warhead. During detonation of the warhead's explosive fill, the casing will break early in the process along predetermined lines resulting in very large fragments that are projected toward the ground and away from innocent civilians. A fragmentation control collar which contacts these charges can be fitted on the outside of existing warheads. An annular liner within the warhead aids in the controlled fragmentation.

  • Patent number: 8955443
    Abstract: A cylindrical warhead is divided into a conical central segment and peripheral segments. The central segment has a disk-shaped liner bounding a cavity with high explosive and forming a penetrating projectile. The peripheral segments are hingedly attached to the central segment and have outer segment faces bounding respective cavities with high explosive, the segment faces forming sidewalls of the warhead in a closed position. The peripheral segments can be released to an open position in which the segment faces point in the forward direction for detonation. The warhead may be used in the closed position for single hardened targets such as armored vehicles and in the open position for area targets such as lighter vehicles and personnel. Opening of the warhead may be enabled at a time of launch of the warhead, or at a time of target acquisition after launch.

  • Patent number: 8522685
    Abstract: A fragmentation warhead includes a cylindrical fragmenting body, a pair of concentric cylindrical liners within, made of plastic, and an explosive charge disposed within the innermost liner. In one embodiment, one liner provides various “legs” of liner material and the other liner provides various open receptacle areas, into which such legs may come to rest when the liners are slid together and/or rotated relative to one another. Various recessed and/or raised areas of liner material can thus be randomly created by such adjustments, which lead to select fragmentation of the warhead upon detonation.

    Abstract: A simple, inexpensive, device and method of use thereof for disrupting the jet of a shaped charge and thereby significantly reducing the penetrating capability by over 90% thereof; thus providing a means to mitigate the damage caused by the premature or accidental jetting of the shaped charge. The device has a central support, along which radiate a plurality of increasing radius, generally hemi-circular, thin discs—such that the outline of the disc edges thereof form a cone that models the interior of the hollow open mouth of the shaped charge—importantly, the discs are staggered along the length of the central support. The device, which can be molded of inexpensive plastic, must be lodged fully within the hollow open mouth of the shaped charge at the time of the premature or accidental jetting—to provide the desired mitigation.

  • Patent number: 7971535
    Abstract: The present invention provides a high-lethality low collateral damage fragmentation warhead. The case is formed of a material that is pulverized upon detonation of the explosive. As a result, the lethality radius of the pulverized case fragments is no greater than that of the gas blast, thus reducing potential collateral damage. Warhead lethality is improved by placing a pattern shaper between the fragment assembly and the explosive. The explosive and pattern shaper have a conformal non-planar interface that shapes the pressure wavefront as it propagates there through to expel metal fragments from the fragmentation assembly with a desired pattern density over a prescribed solid angle.

  • Patent number: 6983698
    Abstract: A shaped charge explosive device which includes an axially symmetric body of explosive material, a liner lining the forward end of the body, and a detonator disposed at the bottom of the body. The liner has an apex disposed along the symmetry axis of the body and the forward end of the body contains a gas filled cavity which overlaps the apex of the liner. When the detonator detonates the explosive material, a detonation wave is produced that collapses the liner into a plurality of liner parts which are projected against an external target. The gas filled cavity shapes the detonation wave so that the detonation wave impacts the liner at the most favorable angle to transfer energy to the liner and maximize the effective penetration of the external target by the projected liner parts.

  • Patent number: 6973878
    Abstract: A kinetic energy rod warhead with aligned projectiles includes a projectile core in a hull including a plurality of individual projectiles and an explosive charge in the hull about the core. The individual projectiles are aligned when the explosive charge deploys the projectiles. The projectiles may also be aimed in a specific direction.

  • Publication number: 20040154492
    Abstract: Encapsulated shaped charge for efficient initiation of hydrodynamic velocity detonation of explosives column. A water tight capsule with angled sides containing sufficient quantities of explosive and a detonator means where the capsule substantially occupies the cross-section of the bore-hole. The capsule contains up to 30 pounds of explosives. The capsule efficiently and sufficiently initiates a column of explosives whereby the amount of Nitrogen Dioxide is substantially decreased.

  • Publication number: 20040055497
    Abstract: A solid explosive munition casing for an explosive charge, the inner surface of the casing including a material that is highly reflective in the optical and infrared spectrum. Through this reflectivity, electromagnetic radiation generated by the detonation process is redirected back into the interior of the munition to increase its explosive output.

  • Patent number: 6622632
    Abstract: The present invention controls the polar ejection angle of fragments in a fragmenting warhead. The warhead's detonators are initiated non-simultaneously to produce corresponding detonation waves in the warhead's explosive material. The detonation waves interact to control the polar ejection angle of fragments formed when the warhead's casing ruptures. Specified times of detonation for each of the detonators can be selected/adjusted after the warhead is deployed.

  • Publication number: 20030172832
    Abstract: An anti-missile missile (10) includes a missile configured to track and intercept an incoming missile travelling along path (12). Missile (10) includes at least one barrel assembly (13) having a multiplicity of projectiles stacked axially within barrel assembly (13), together with discrete selectively ignitable propellant charges for propelling the multiplicity of projectiles sequentially through the muzzle of barrel assembly (13). The multiplicity of projectiles produce a fragment column (20) along path (12) to destroy the incoming missile. Alternatively, anti-missile missile (10) can be guided to produce a direct hit at point (18) on the incoming missile. Barrel assembly (13) can include an aiming mechanism so that barrel assembly (13) can be rotated through sector (15, 16) to target path (12).

  • Patent number: 6619210
    Abstract: A warhead casing defines a geometry that is a portion of a ring having an outer radial wall and an inner radial wall spaced radially apart from one another. The outer radial wall and inner radial wall are joined radially by side walls, while the casing is enclosed at either axial end thereof by end walls. An explosive material fills the casing. At least one initiator is positioned in the explosive material along a radial plane that bisects the portion of the ring. Detonation of the explosive material causes the inner radial wall to form an EFP while the outer radial wall fragments.

  • Patent number: H2236
    Abstract: A method is provided for destroying a target that includes dispersing submunition fragments in an array that is directed to intercept the target, and engaging said fragments to collide against an outer shell of the target, wherein said array distributes said fragments as having a ratio between a characteristic length of said fragments and a separation distance of at most 2.5 and a collision velocity of between 1.8 km/s 2.0 km/s. The ratio is preferably at most 1.9. The characteristic length corresponds to a spherical radius of the fragment. Each fragment has a mass between 150 grains and 300 grains. The array is preferably aligned to intercept the target at an angle offset by between 15° and 45° from perpendicular to a longitudinal axis of the target. Each fragment has a preferable shape of a prism, a trapezoid or a pyramid.
