  • Patent number: 8387539
    Abstract: Bombs lined with reactive liners that improve the blast and fragmentation of the bombs is disclosed. The effect is caused by the Richtmyer-Meshkov instability which is introduced at the explosive/reactive liner interface by introducing semi-cylindrical open linear cells between the reactive liner and the explosive that are void. This geometry produces a turbulent flow effect which readily mixes the reactive liner when accelerated by the grazing shock wave generated during detonation, which moves through the liner and case material. The geometry produces the added effect of creating faster and more plentiful fragments that are lighter in mass than those produced by typical bombs that are annularly lined with reactive liners, while maintaining insensitive munitions capability.

    Abstract: The dynamically configurable controlled fragmentation insert mechanism of this invention includes an assembly of three or more sleeves with differing through hole patterns thereon, that fit inside the shell casing. The individual sleeves can move independently of one another and a simple pinning mechanism holds the parts in place for a selected configuration. The warfighter can realign the insert sleeves by to create different geometric patterns of holes, each designed to engage a different target set with optimally sized fragments. The aligned patterns of holes creates individual geometric shapes that focus high-velocity jets to cut into the steel shell casing to correlate to the through-holes in the aligned patterned sleeves. Realigning the insert sleeves changes the through-hole pattern to produce different fragment sizes and mass distributions.

  • Patent number: 7886667
    Abstract: A warhead includes a body, a patterned liner made of plastic, and an explosive charge disposed within the liner. The liner pattern is formed of gaps and liner elements. The explosive charge includes a first set of sections that are disposed adjacent to the liner gaps and a second set of sections that are disposed adjacent to the liner elements. Upon detonation of the explosive charge and because of the temporal delay in transmitting the detonation energy between these two sets of sections, the warhead body is caused to shear and break into fragments with controlled size. The use of plastic as the liner material also provides a welcome safety feature for this warhead. In the event of unwanted heat ignition, the plastic (which is also low melt temperature material), would melt to seal the explosive and would also flow. Because of the plastic, neither sudden pressure nor heat/ignition inside the round, would therefore be as catastrophic.

Upon impact with a target the impact switch sends a detonation signal to a detonator positioned at the rear end of the warhead causing the shaped charge to initiate. Upon the detonation of the rear shaped charge, a high-speed shaped-charge jet forms into the hollow jet formation region, penetrates into and initiates the forward fragmentation charge, and continues through the fragmentation charge. The residual shaped charge jet provides lethality against light armored targets while the fragmentation from the forward charge provides lethality against personnel and other soft targets.

  • Patent number: 6789484
    Abstract: Projectiles or war-heads with an inner arrangement for the formation of bulging zones (4,4a) are proposed, comprised of an enclosed bulging medium (1) which is terminal-ballistically substantially ineffective and is radially enclosed by a penetration material (2) which is terminal-ballistically effective, with the bulging medium (1) having a lower density as compared with the enclosing penetration material (2). This leads to the effect that on impact or on penetrating a target plate (3) the bulging medium (1) remains behind relative to the encompassing terminal-ballistic effective body (2) and is laterally increasingly bulged by the bulging material (1) which continues to flow in from behind. As a result of the high pressures, a conical (crowned) pressure and bulging zone (4,4a) is formed dynamically, which zone radially widens or fragments the passing ambient effective material (5,5a).

  • Patent number: 6283036
    Abstract: This invention involves a hard target penetrating warhead designed to produce a variable explosive discharge. A standard warhead casing is divided into several compartments with each compartment separated by a shock-absorbing shield. Explosive fill in contained within each compartment. The shock-absorbing shield inhibits the dynamic shock produced by detonating a compartment, thus preventing sympathetic detonation of adjoining compartments. As a result, the size of an explosive blast is controlled by detonating the explosive fill, in a set number of compartments. Each compartment also contains an igniter element, which initiates a slow burn of undetonated explosive fill.

  • Patent number: 5939663
    Abstract: A method and apparatus are provided for selectively producing a coherent or ispersed jet pattern upon detonation of a shaped charge ammunition round. Multiple detonators are provided which may be arranged in a symmetrical or non-symmetrical pattern around or on the axis of the charge. Selection of a coherent or dispersed jet pattern may be provided by controlling the number and timing of detonators used. A coherent jet may be produced, for example, by actuating only one detonator along the centerline of the round. Dispersed jets in selected patterns may be achieved by actuating multiple detonators in different patterns.

  • Patent number: 5852256
    Abstract: A non-nuclear, non-focusing, active warhead that comprises a high explosive charge contained within a casing of reactive metal. When the high explosive is detonated, the reactive metal is dispersed and reacts with the air, which significantly increases the explosive yield of the warhead. The active warhead produces therefore much higher blast effects with significantly reduced weight compared to conventional munitions. The warhead is highly effective against such targets as aircraft which typically have thin fuselages, for example. The explosiveness of this warhead can be enhanced further by elevating the temperature and therefore the reactivity of the reactive metal before or during the explosion. New methods of enhancing the reactivity of the metal are also taught.
