20140299012FRAGMENTATION-BEAM TANK PROJECTILE - This invention relates to fragmentation-beam ammunition capable of simultaneous axial and circular field destruction.10-09-2014
20160054107CONTROLLED FRAGMENTATION OF A WARHEAD SHELL - 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.02-25-2016

20090199736MCD SHELL - The present invention relates to a method for firing explosive-filled, fragmentation shells (08-13-2009
20100199875PROJECTILE OR WARHEAD - The aim of the invention is to obtain great final ballistic effectiveness of fragmentation bullets and warheads regardless of the impact speed while using as little explosive material as possible. Said aim is achieved by combining explosive shell (08-12-2010
20110094408FORWARD FIRING FRAGMENTATION WARHEAD - A forward firing fragmentation warhead is constructed with casing materials that are 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 may be improved by forming the fragmentation layer and explosive with dome-shapes that approximately match the shape of the advancing pressure wave. This increases fragment velocity and improves the uniformity of the fragment distribution over the forward-firing pattern. A variable-thickness pattern shaper may be placed between the fragmentation layer and explosive to provide additional shaping of the forward-firing pattern. Warhead weight and cost can be reduced by eliminating explosive at the aft end of the warhead that does not contribute to the total energy imparted to the fragments. More specifically, the aft section of the explosive and explosive containment structure may be tapered to approximately match the expansion of the pressure wave from the single-point aft detonation.04-28-2011
20110179966DUAL-MASS FORWARD AND SIDE FIRING FRAGMENTATION WARHEAD - A high-lethality fragmentation warhead with reduced risk of collateral damage to the warhead launch platform. High lethality is achieved with a forward-firing fragmentation assembly placed in front of the explosive and a side-firing fragmentation assembly placed in a void space in the aft section of the explosive. The risk of collateral damage to the launch platform is reduced by forming the case and explosive containment structures of materials that are pulverized upon detonation of the explosive. This substantially eliminates radial fragments and in particular fragments thrown back towards the platform. Performance may be enhanced by tapering the aft section of the containment structure and explosive to eliminate explosive that does not contribute to the total energy imparted to the forward-firing fragmentation assembly by the pressure wave to create the void space for the side-firing fragmentation assembly. Performance may be further enhanced by forming the end of the explosive and forward-firing fragmentation assembly with largely conformal dome shapes that approximately match the shape of the front of the pressure wave. This both increases the amount of explosive energy delivered to those fragments and serves to expel them in a desirable pattern.07-28-2011

20140230682RADIAL FIRING WARHEAD SYSTEM AND METHOD - A warhead system, method and apparatus. A warhead includes a liner having a logitundinal axis that runs down the center of the liner. The liner includes a liner pattern and a liner shape. The liner shape is selected and a radial distance from the longitudinal axis is selected. The liner pattern is warped as a function of the selected distance and the shape of the liner to reduce the effects of spoking in the post-detonation fragmentation pattern at the selected distance. The liner is then formed as a function of the warped liner pattern.08-21-2014
20160025467LOW-COLLATERAL DAMAGE DIRECTED FRAGMENTATION MUNITION - A directed munition has a non-fragmentation casing, and an explosive within the casing that is configured to propel fragments out an opening of the casing when the explosive is detonated. The casing may be made of a material that does not produce lethal or injurious fragments when the explosive is detonated. The explosive may include an insensitive explosive portion that creates the shape of an explosive front, and a secondary explosive containing a more energetic explosive, which is closer to the fragments than the insensitive explosive portion. There may be more of the insensitive explosive than the relatively energetic explosive. The munition may have a ring that is operatively coupled to the fragments, to aid in directing the fragments out of the casing opening in a desired direction. The ring may be made of a material that does not produce injurious fragments when the explosive is detonated.01-28-2016

20160377396MUNITION WITH MULTIPLE FRAGMENT LAYERS - A munition has preformed fragments at two radial distances from a center axis, for instance having inner fragments in or within or adjacent to a casing, and outer fragments outside of the casing.

The fragments at different radial distances from the center may have different sizes, different materials, and/or different shapes. The use of fragments at different radial distances aids in providing enhanced fragmentation effects, such as controlling dispersal of fragments to limit fragmentation effects and/or provide more even distribution of fragments.12-29-2016

20110146523HIGH-LETHALITY LOW COLLATERAL DAMAGE FRAGMENTATION WARHEAD - 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.06-23-2011
