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.

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.

Abstract: An apparatus and method for disarming improvised bombs are disclosed. The apparatus comprises a fluid-filled bottle or container made of plastic or another soft material which contains a fixed or adjustable, preferably sheet explosive. The charge is fired centrally at its apex and can be adjusted to propel a fluid projectile that is broad or narrow, depending upon how it is set up. In one embodiment, the sheet explosive is adjustable so as to correlate the performance of the fluid projectile to the disarming needs for the improvised explosive device (IED). Common materials such as plastic water bottles or larger containers can be used, with the sheet explosive or other explosive material configured in a general chevron-shape to target the projectile toward the target. In another embodiment, a thin disk of metal is conformably mounted with the exterior of the container and radially aligned with the direction of fire of the fluid projectile.

Abstract: The fly over homing guidance system for terminal homing missile guidance is fire and forget missile guidance method wherein on board target sensing tracks the target and guides the missile to the target, but instead of being guided to a direct impact as is conventionally done, the missile is guided toward a precise distance over the top of the target, intentionally avoiding impact. A second sensor on the missile detects the leading edge of the target, such as the turret of a tank. The warhead is then fired down onto the top of the target as the missile is guided or directed over it. Further, the shot line of the warhead is substantially perpendicular to the top of the target, maximizing lethality. This allows the use of the same angle of attack and warhead for all modes of target engagement and thus maintains high lethality for every firing scenario.

Abstract: A missile includes a warhead accommodated in an inner space at a front portion of the missile; a ball joint being in alignment with the longitudinal missile axis and pivotally supporting the warhead; and an aiming device for placing the warhead into a desired pivotal orientation. The aiming device includes a plurality of inflatable vessels arranged axially adjacent the warhead in a distribution about the missile axis. Each vessel has a first end oriented toward the warhead and a second end oriented away therefrom. The vessels are supported at their second end by a disk situated in the inner space of the missile. A gas generator is coupled to each vessel for charging the vessel with a gas to place the vessel into its inflated state. In the inflated state each vessel exerts a torque on the warhead about the ball joint by an engagement between the first end of the respective vessel and the warhead. Further, an electronic control system is accommodated in the inner space of the vessel.

Abstract: An axially extending fragmentation warhead having a plurality of separate axially extending deformation charges in its radially outer surface. The deformation charges are located in a damping layer enclosing a fragmentation layer covering a cylindrical jacket enclosing a main explosive charge. The deformation charges facing a target can be individually ignited to inwardly deform the cylindrical jacket and the fragmentation layer prior to igniting the main explosive charge for selectively directing the fragmentation layer at the target. The deformation charges can be ignited individually or in selected groups to increase the effectiveness of the fragments directed at the target.

Abstract: A solid explosive charge is provided with plural detonators on its outer surface at locations from which divergent shock waves simultaneously emerge for movement inwardly of the explosive body. Such shock waves form an uninterrupted wave front enclosing a progressively decreasing volume of the explosive as it converges toward the center of the charge to correspondingly increase peak implosion pressure within a body of water.

Abstract: A novel warhead employing a unique shaped charge liner design is disclosed. particular construction of the liner is described whereby the fabrication process uses three radii of curvature to generate an arcuate design which is convex when viewed from the open end. This liner design is capable of producing two distinct jets; a front or precursor jet consisting of small diameter particles traveling faster than a secondary or main jet and consists of larger diameter particles.

Abstract: The detonation wave velocity in a solid explosive body of material, incred by the "channel effect", is further increased by compounding of the "channel effect" and/or by partial shock wave interruption by means of a threaded or rifled passage wall surface in a continuous, open channel arrangement. The high velocity detonation wave can be used to increase the jet velocity of shaped charges.

Abstract: An explosive round is formed by a bundle of fibers made of explosive matel held in peripheral contact with each other within an outer casing. Axially extending channel passages thereby extend between the fibers to conduct shock waves periodically impacting explosive blockage plugs in order to generate auxiliary detonation waves in forward and reverse directions. The auxiliary waves propagated in the reverse direction collide with the original detonation wave in the fibers between the blockage plugs at the locations of axial gaps between the fiber segments so as to reduce peak pressure oscillation.

Abstract: A selectable fragmentation warhead capable of producing a predetermined number of fragments from a metal plate, and accelerating the fragments toward a target. A first explosive located adjacent to the plate is detonated at selected number of points by laser-driven slapper detonators. In one embodiment, a smoother-disk and a second explosive, located adjacent to the first explosive, serve to increase acceleration of the fragments toward a target. The ability to produce a selected number of fragments allows for effective destruction of a chosen target.

Abstract: In an explosive device having a main charge explosive, a booster explosive mbedded in the main charge explosive, and a detonator, a can or plate is embedded in the main charge explosive and provides a high impedance surface which is shaped and oriented so that shock waves from the booster explosion will strike the high impedance surface at normal incidence and be reflected back toward the booster explosion. This increases the pressure in the main charge explosive material between the booster explosive and the can or plate, thus increasing the effectiveness of the booster explosive.

Abstract: A system for aiming a selectively aimable warhead (SAW) at a target by exsively deforming the warhead into a shape desirable for directionality. Twenty-four explosive forming charges are located around the circumference of the warhead and run the entire length of the warhead. The proximity fuze selects one sector out of 24 as the direction aim. Having selected a sector in the azimuth, the forming charge in that sector plus the adjacent two forming charges are initiated simultaneously. After a time delay interval sufficient to allow the warhead to deform (about 1/2 millisecond to 1 millisecond), warhead boosters located furthest from the target (or 180 degrees from the forming charges) and on each end of the warhead, are initiated simultaneously. The warhead is detonated generating a high velocity fragment beam towards the target.

Abstract: An explosive fragmentation device such as a grenade or a mortar bomb has a casing formed from flat sided notched wire formed into a coil. Instead of coiling the wire so that sides of the coiled wire which are adjacent after coiling lie normal to the longitudinal axis of the coil, as in a known form of grenade body, the wire is given additionally a twist about its own longitudinal axis during coiling, so that the adjacent flat faces of adjacent turns are substantially normal to the surface of the finished casing. In this way adjacent turns overlay one another, preferably completely, and the outer surface of the casing can then be smooth. Also, adjacent turns can then be bonded together as by brazing or soldering, which is impractical with coiling "normal to the axis". This means explosive cannot be trapped between adjacent turns to be accidentally detonated, an outer casing is unnecessary, and the casing is stronger.

Abstract: An explosive body having an intensified detonation pressure is disclosed, characterized in that the body includes a main explosive charge and an auxiliary explosive charge. A material is arranged between the charges for transmitting the impact wave from the detonating auxiliary charge to the main charge. Detonation of the main charge is delayed following detonation of the auxiliary charge, whereby the impact wave of the auxiliary charge compresses the explosive of the main charge. Thus, the intensity of the resulting detonation pressure of the main charge is increased.

The forward composition, preferably incendiary, is encompassed by a ballistic hood, the rearward composition being at least partially of explosive material is detonatable by an impact detonator. The head portion of the penetrating member is formed of two regions having different slopes to increase the activity of the projectile at flat striking angles against a target. The two regions are separated by a sharp-edged gripping edge. The penetrating member may also include in the interior thereof a plug of a pyrophorically acting metal or alloy.

Abstract: This invention involves a hard target penetrating warhead designed to penetrate several layers of a target. 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. Each compartment also contains a delay element, which permits each compartment to be ignited at the desired time. This allows the warhead to destroy a layer of a target then proceed to the next layer or layers, eliminating the need for several missiles to destroy the entire target.
