Abstract: A spinner apparatus is disclosed herein. In one embodiment, the spinner comprises a magnetic ring; a rod, wherein the rod extends through the middle of the magnetic ring; and a first cap, wherein the first cap connects to a first end of the rod; and a second cap, wherein the second cap connects to a second opposite end of the rod. In another embodiment, the spinner comprises a first magnetic ring; a second magnetic ring; a magnet spacer, wherein the magnet spacer is disposed between the first and the second magnetic rings; a rod, wherein the rod extends through the middle of the first and the second magnetic rings; a first cap, wherein the first cap connects to a first end of the rod; and a second cap, wherein the second cap connects to a second opposite end of the rod.

Abstract: 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.

Abstract: 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.

Abstract: A munition may include a warhead, such as a penetrator warhead, enclosed in airframe. The airframe may enable connection to standard mountings, and/or to standard nose kits or tail kits. The airframe may have preformed fragments in it, packed between the airframe and the warhead. The preformed fragments may be loose, may be packed in a potting material, or may be in flexible bags. The fragments may enhance performance of the munition. The warhead may also contain preformed fragments.

Abstract: 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.

Abstract: A shock mitigation assembly for a penetrating explosive weapon having a first explosive charge and a second explosive charge includes an electronic circuit card having an electronic circuit formed therein, a weight attached to the circuit card to form a circuit card subassembly, a housing enclosing the subassembly, and a hyperelastic material between the housing and the subassembly for internal shock mitigation. The hyperelastic material has a modulus of elasticity that remains elastic characteristics with shock, temperature, or a combination of shock and temperature. The housing may include a casing and a cover with corresponding features that mate with one another and prevent separation of the cover from the casing. The casing also may have an external spiral flange that overlaps an internal spiral flange of a support for the casing, with a hyperelastic material between the casing and support for external shock mitigation.

Abstract: A munition, such as a warhead, includes a penetrator casing for penetrating hard targets, such as a fortification or inforced building or other structure, with the penetrator casing having reduced-thickness portions. The munition also includes a shock-resistant fuzewell for absorbing shocks during the penetration, to allow a fuze within the fuzewell to survive hard target penetration. The fuzewell may have one or more shock-absorbing features, such as having a ring surrounding a central housing, with flexible spokes connecting the ring to the central housing. The shock-absorbing features may allow the fuze to withstand the penetration into a hard target, with the fuze subsequently being used to detonate an explosive of the munition.

Abstract: A munition that is adapted to enhance fragmentation effects upon detonation includes preformed fragments between a casing and a shell. The overall mass of the preformed fragments is greater than the overall combined mass of the casing and the shell for enhancing the degree of controlled fragmentation compared to uncontrolled fragmentation. By enhancing the dispersal of controlled fragmentation, the overall fragmentation area coverage and fragmentation pattern density may also be enhanced while limiting travel of the fragmentation beyond the target area for reducing collateral damage. The preformed fragments may fill a continuous volume between the casing and the shell to effectively utilize the munition volume and to maximize the amount of preformed fragments contained within the shell. The preformed fragments may be free flowing pellets that are poured into the volume between the casing and the shell for enhancing distribution of the fragments and for improving assembly of the munition.

Abstract: A munition has a fuze that is mounted nonparallel to the axis of the munition, for example having a largest extent that is perpendicular to the longitudinal axis of the munition. Shocks from the fuze are transferred through a shock transfer device that is in contact with the fuze, to an initiation device that is also in contact with the shock transfer device. Shocks passing through the shock transfer device to the initiation coupler pass through a relatively narrow neck of the shock transfer device. In the shock transfer device the shock is concentrated and located precisely at the neck, before spreading out again and being transferred to the initiation device. In the initiation device the shock may detonate a high explosive material, which in turn is used to detonate a main explosive of the munition, such as a warhead.

Shocks from the fuze are transferred through a shock transfer device that is in contact with the fuze, to an initiation device that is also in contact with the shock transfer device.

In the shock transfer device the shock is concentrated and located precisely at the neck, before spreading out again and being transferred to the initiation device. In the initiation device the shock may detonate a high explosive material, which in turn is used to detonate a main explosive of the munition, such as a warhead.
