  • Patent number: 10690459
    Abstract: A fuze booster includes a first explosive charge having a cavity with an annular portion of the first explosive charge encircling a first axial portion of the cavity and a semi-annular portion partially encircling a second axial portion of the cavity. The annular portion abuts the semi-annular portion. An explosively-inert material abuts the semi-annular portion, abuts the annular portion, and partially encircles the second axial portion of the cavity. A second explosive charge abuts the explosively-inert material, abuts the semi-annular portion, and partially encircles the second axial portion of the cavity. The second axial portion of the cavity is thus completely encircled by a combination of the semi-annular portion, the explosively-inert material, and the second explosive charge.

  • Patent number: 8943971
    Abstract: Compounded High Explosive Composites provide a novel family of low-cost explosives that exhibit anisotropic (directionally dependent, non-symmetric) sensitivity properties to replace current homogenous plastic bonded high explosives that are vulnerable to unwanted detonation from a variety of hazards and operating conditions. Anisotropic sensitivity behavior is largely achieved by manipulating the bulk property of critical diameter to fine-tune the compounded geometry of the explosive composite. As such, Compounded High Explosive Composites represent structural arrangements of small, spatially distributed, highly consolidated explosive units (pellets) arranged in a prescribed (but versatile) fashion in a motion and energy-dampening rubbery matrix. The compounded geometry and structural arrangement allows the explosive pellets to function cooperatively and detonate in an exemplary orientation, while ensuring the pellets do not cooperate in other directions to mitigate against known vulnerabilities and threats.

  • Patent number: 6962113
    Abstract: The present invention comprises a warhead designed to provide a number of spiraling tendrils composed of segmented rods that move in an increasing radial arc in order to defeat a target. The warhead comprises a substantially cylindrical explosive charge having a plurality of rod segments arranged circumferentially around the explosive charge in a plurality of horizontal layers. As the horizontal layers descend down the explosive charge, the rod segments are offset from those directly above and below them to create a pattern that appears to be twisted columns. The number of columns is equivalent to the number of rod segments in each horizontal layer.

  • Patent number: 6499706
    Abstract: The present invention is an emplacement stand for holding explosive ordnance disposal tools that comprises a support base having tapered pegs evenly spaced around the outside of the support base extending outward at a downward angle. Detachable legs may be attached to the tapered pegs or each other to increase the height of the support base. A pivot arm slides through a hollow bearing ring within the support base and a set screw connector locks the pivot arm into a specific desired position after moving the pivot arm up or down within the support base. A pivot base, having a tool cradle connected to a disc shaped surface attaches to a clevis slot within the pivot arm through a pin that allows the disc shaped surface to freely pivot about the pin within the slot. A second set screw connector locks the disc shaped surface into place within the clevis slot.
