摘要： A projectile round for intercepting an incoming threat to a vehicle or the like is provided. The projectile round may include an explosive layer, which upon detonation, may cause a the fracturing of one or more material layers into one or both of shrapnel and chaff while simultaneously causing the distortion and/or destruction of a piezoelectric material contained within the projectile round. The distortion and/or destruction of this piezoelectric material may further cause the release of an electromagnetic pulse. The projectile round may be part of a countermeasure system against guided munition threats, including those posed by man-portable air defense systems.

摘要： 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 outer fragments may be between the casing and an outer enclosure that surrounds the casing. The casing may be part of a warhead, and may be a penetrator 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.

摘要： A munition, such as a warhead, includes a penetrator casing for penetrating hard targets, such as a fortification or reinforced building or other structure, with the penetrator casing having reduced-thickness portions. The reduced-thickness portions provide weak points to the casing that facilitate the casing being transformed into fragments of a desired size/quantity when an explosive within the casing is detonated after the penetration occurs, thus enhancing the effectiveness of the munition. In addition, the warhead may have lethality-enhancing materials, such as additional fragments and/or energetic materials, at the reduced-thickness portions of the penetrator casing. The reduced-thickness portions may be holes, such as longitudinal holes, in the casing, or may be grooves on an inner and/or outer surface of the casing. The munition may be a dual-use munition, with the explosive able to be detonated at a burst height for use of the warhead as a non-penetrating area fragmentation weapon.

摘要： A munition, such as a warhead, includes a penetrator casing for penetrating hard targets, such as a fortification or reinforced building or other structure. The penetrator casing has a relatively thick nose, and a relatively thin aft section extending back from the nose. A cable interface is in the aft section, and an electrical harness extends from the cable interface, external of the casing, and forward to a nose kit. The penetrator casing may have reduced-thickness portions, to provide weakness points to the casing that facilitate the casing being transformed into fragments of a semi-controlled and desirable size when an explosive within the casing is detonated after the penetration occurs, thus enhancing the effectiveness of the munition.

摘要： A multi-warhead munition includes a first cylindrical warhead having a cavity filled with high explosive, and a second cylindrical warhead offset axially from the first cylindrical warhead. The second cylindrical warhead is a transformable, segmented warhead including a plurality of segments each having an outer segment face bounding a cavity of the segment filled with high explosive. The segments are elongated and mounted at one end for rotation away from an axis of the munition to an open position in which the segment faces are pointed in a forward direction for detonation. Rotation may generally be somewhere in a broad range from about 105 degrees to about 170 degrees, obtaining different effects in different sub-ranges. The munition includes first and second detonators for the first and second cylindrical warheads respectively, the second detonator simultaneously detonating the segments of the second cylindrical warhead.

摘要： Described herein is a munition to be exploded in the air at a position above an intended target. The munition includes an explosive, a matrix of fragmentation material, a body part with a convex shaped support element and a detonator. The layered structure of the munition is such that when detonated, a directional explosion code of fragmentation material is formed in a delimited distribution pattern. The munition can be arranged within a takeoff canister with a takeoff charge.

摘要： A system and method is provided for detecting the trajectory of multiple fragments through a conic or cylindrical section, such as the body of a missile. Three or more sensors are placed on the on the body of the object. Each of the sensors is constructed and arranged to measure signals to the sensor at from impacts on one or more locations on the body. The sensor then transmits a signal commiserate with the impact of a fragment thereon. A computer system is also provided to perform necessary calculations and, potentially, record the impact times and locations. When the body of the object is hit by fragments or shrapnel, a signal from one or more of the sensors is sent to the computer system. This operation is performed and constantly updated for all locations where a fragment is detected by one or more of the sensors. Waveforms of the impacts are recorded, but because multiple hits can occur, there can be superposition (or destruction) of the resulting waveform sent to the computer system. The computer system can interpret which superposition or destruction is indicative of another fragment strike, and filter out those additions or subtractions to the waveforms that could not possibly be from another fragment.

摘要： A method of modifying material properties of a fragmentation device, includes providing a fragmentation device with a first surface, a first section, a second section, a second surface spaced apart from the first surface, a third section, and a fourth section disposed between the first, second, and third sections. The method further includes positioning the fragmentation device within a carbon-rich environment, and absorbing carbon from the carbon-rich environment into the first and second surfaces of the fragmentation device. Additionally, the method further includes increasing a content of carbon at the first and second surfaces of 0.06 wt. % carbon to 1.0 wt. % carbon and maintaining an original content of carbon of 0.01 wt. % carbon to 0.05 wt. % carbon at the fourth section of the fragmentation device by controlling penetration of the carbon into the fourth section.
