Abstract: This application discloses a shaped charge firearm projectile that includes a two-piece jacket that defines an internal cavity with an opening in the front side of the jacket that is part of the internal cavity, a detonator positioned in the internal cavity, a striker passing through the opening with one end positioned outside of the internal cavity and the other end positioned near the detonator inside of the internal cavity positioned to detonate the detonator when the striker impacts a target with sufficient force, and a main charge positioned in the internal cavity with the main charge and the jacket defining an air-filled chamber located between the front side of the jacket and the main charge, where the striker extends into the main charge.

Abstract: A liner assembly for an explosively formed projectile device may include a reactive material liner and a primary liner configured to form into a projectile responsive to initiation of an explosive material. The reactive material liner may be configured and formulated to increase the velocity of the projectile after formation thereof. An ordnance device for generating an explosively formed projectile may include a case, an explosive material, and a reactive material liner and a primary liner configured, in combination, to form into a projectile. An explosively formed projectile may include a deformed primary liner and a deformed reactive material liner having an ignited portion increasing the velocity of the projectile. Methods of explosively forming a projectile may include explosively expelling a primary liner and a secondary liner and increasing the velocity of the projectile by combusting at least a portion of the secondary liner.

Abstract: 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 pre-determined lines resulting in very large fragments that are projected towards 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.

Abstract: A case for a warhead having a plurality of elongated wires which are braided or woven together to form a mesh which is formed into the shape corresponding to the warhead case. The mesh is impregnated with a polymer matrix which, upon curing, forms a rigid warhead case. At least some of the elongated wires include notches at selected locations which form fracture points which shape a blast from a subsequent explosion of the warhead.

Abstract: A method and apparatus is described for modifying downhole wellbore pressure at the instant that an explosive event occurs. By a significant temporary reduction in wellbore pressure, for example, an explosive cutter will be able to cut through thicker pipe in a deep well with high hydrostatic pressure. A favorable transient wellbore pressure is achieved by the selective timing of implosion and explosion devices, to improve the performance of certain explosive tools when subsequently initiated, such as shaped charge explosive cutters, severing tools, setting tools and perforating guns. As part of the system, each implosion or explosion device is initiated by a detonator having a preprogrammed control unit with a preselected timing delay to take advantage of the temporarily lowered wellbore pressure.
