Abstract: A fragmentation casing is defined by a monolithic tube having a solid radial wall and a pattern of tunnels defined in the solid radial wall. The tunnels may be filled with air, a powder that is a powdered form of the material used to make the solid radial wall, or a solid material that is the same as the solid radial wall but whose mechanical attributes differ from those of the solid radial wall.

Abstract: A fragmentation casing includes a monolithic tube defined by an alternating axial arrangement of first and second rings. Each first ring is a contiguous ring of fused powder defining spaced-apart first elements of the fused powder and at least one second element of the fused powder joining adjacent ones of the first elements. Each second ring is a contiguous lattice of the fused powder. Each of the first elements is contiguous with a portion of the lattice associated with at least one of the second rings.

Abstract: A shock mitigation casing includes a monolithic body made from a solid material. The monolithic body includes a first wall, a second wall spaced apart from the first wall, and axial end walls contiguous with the first wall and the second wall. A chamber is defined between the walls. A powder fills the chamber. The powder is a powdered form of the solid material.

Abstract: A warhead device of an ordnance including a body of a high strength material, where the body includes a plurality of depressions; an explosive material, where the explosive material fills the body; and a plurality of reactive materials, where each reactive material fills a corresponding depression of the plurality of depressions on the body. The high strength material is configured to endure an internal stress, a first stress caused by the plurality of reactive materials, and a second stress caused by another component of the ordnance. The internal stress, the first stress, and the second stress are in response to acceleration of the ordnance.

Abstract: The present disclosure relates to systems and methods for explosive systems such as grenades with novel micro-electromechanical systems (MEMS) fuze and novel placement of the MEMS fuze providing increased performance, reliability, and safety. The MEMS fuze is disposed towards a rear portion of the explosive system providing superior performance and design flexibility. Further, the explosive system includes electronics configured to implement a launch timer and to sense impact or when the system stops spinning. The present invention includes an operational method improving safety and reliability by preventing detonation until after the launch timer expires, upon impact, or when the explosive system stops spinning.
