  • 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.

  • Patent number: 8272329
    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: 8161884
    Abstract: A selective fragmentation pattern of explosive material is applied to a surface of a munition. None, some, or all of the explosive material in the selective fragmentation pattern may be detonated, selectively stamping the surface of the munition with the detonated explosive material. The portion of the selective fragmentation pattern selected for ignition is determined by lethality requirements of a target of the munition. Upon detonation of the munition, fragments are formed based on the selected portion of the selective fragmentation pattern. Consequently, igniting all, some, or none of the selective fragmentation pattern may vary lethality of a munition and one munition may be used for a wide range of lethality.

  • Patent number: 8006623
    Abstract: 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.

  • 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: 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.

  • 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: 6895864
    Abstract: The present invention relates to a segmented subcaliber projectile (1) subdivisible into a number of separate segments contiguous with each other at least initially to form an integral projectile of united segments or submunitions (5). The advantage with this subcaliber projectile is that since the segments or submunitions (5) are arranged sequentially after each other, each one comprises an explosive charge (7) initiatable by a very powerful shock and encased in an outer casing (6) of hard material such that the projectile in integral form can be used directly against heavy armor, and by means of dispersion of the various segments can also be used against aircraft.

  • Patent number: 6536351
    Abstract: A warhead (1) having a warhead casing (2) that encloses an explosive charge (5). To ensure that, during the detonation of the explosive charge (5), the warhead (1) effects a rapid acceleration of the fragments flying in the flight direction, and a lesser acceleration of the fragments flying away laterally from the warhead, and/or generates a relatively intense lateral pressure wave, the charge has at least two different partial charges (7, 8-10) corresponding to the intended use of the warhead (1). The first partial charge (7), which is disposed in the region of the tip of the warhead (1), and comprises, for example, octogen (HMX), possesses a high detonation speed in order, when detonated, to accelerate heavy-metal fragments (preferably WSM spherical fragments) disposed in front of the partial charge very rapidly forward. In contrast, the second partial charge (8-10), which adjoins the rear of the first partial charge (7), is a far less costly charge, e.g.
