Provided herein are shaped charges for focusing a fluid mass and related methods of using the shaped charges for disruption of an explosive target. The shaped charge comprises a plastic shell having a special geometric shape configured to support a shape-conforming explosive. A cylindrical plastic body has an interior volume for containing a fluid and the plastic shell. The plastic body closed distal end has a geometric shape that is substantially matched to the shape of the plastic shell.

A configurable fluid vessel comprising a flexible bladder (45) having a fluid port (47) through which a fluid such as water can be provided into the bladder (45). The fluid vessel further comprises an internal support frame (43) within the flexible bladder (45) to increase rigidity and preferably an urging means (44) for urging the flexible bladder (45) into a predetermined shape. The fluid vessel is collapsible for storage whilst retaining rigidity when in use. The fluid vessel is particularly suited for use in explosive jet disruptors (40) for tailoring the formation of a fluid jet.

Provided herein are fluid jet enhancement adapters for use with a propellant driven disrupter, and more particularly muzzle blast suppressor. The fluid jet enhancement muzzle blast suppressor may comprise a suppressor bore extending between the proximal end and the distal end with an inner suppressor surface that defines the suppressor bore. An outer suppressor surface opposably faces the inner suppressor surface, with a suppressor chamber positioned between the inner and outer suppressor surfaces. A plurality of passages connect the suppressor bore with the suppressor chamber, wherein the plurality of passages are sized to allow gas to move from the suppressor bore to the suppressor chamber and minimize liquid movement from the suppressor bore to the suppressor chamber.

Provided herein are fluid jet enhancement adapters for use with a propellant driven disrupter. The adapter may comprise: a first end operably connected to a muzzle end of a propellant driven disrupter barrel and a second end, wherein a longitudinal region extends between the first end and the second end. The longitudinal region has: a longitudinal region inner surface that defines a longitudinal region lumen; a longitudinal region outer surface opposably facing the longitudinal region inner surface, with a longitudinal region wall having a wall thickness that separates the longitudinal region inner surface from the longitudinal region outer surface. The longitudinal region lumen has a first end inner diameter that is substantially equivalent to a muzzle inner diameter. The longitudinal region wall forms a continuous surface that radially isolates the longitudinal region lumen from a surrounding environment.

A disrupter for launching a combination of a liquid and a projectile toward an explosive device to strike the explosive device to disable the explosive device. The position of the projectile in the barrel of the disrupter determines an exit velocity of the liquid and the projectile from the barrel of the disrupter.

A novel dearmer enables EOD technicians to propel dearmer projectiles using conventional electric .50 caliber blank cartridges or conventional non-electric 12 gauge blank cartridges. The dearmer projectiles may render energetic threats safe without requiring an opposing force to offset the recoil. The conventional blank cartridge functions as a rocket motor that supplies gas to a converging/diverging nozzle. Alternatively, liquid is loaded into the dearmer (creating a liquid rocket effect) and the EOD projectile is propelled toward a target from the end of the dearmer opposite the liquid.

Provided herein are fluid jet enhancement adapters for use with a propellant driven disrupter, and more particularly muzzle blast suppresser. The fluid jet enhancement muzzle blast suppresser may comprise a suppresser bore extending between the proximal end and the distal end with an inner suppresser surface that defines the suppresser bore. An outer suppresser surface opposably faces the inner suppresser surface, with a suppresser chamber positioned between the inner and outer suppresser surfaces. A plurality of passages connect the suppresser bore with the suppresser chamber, wherein the plurality of passages are sized to allow gas to move from the suppresser bore to the suppresser chamber and minimize liquid movement from the suppresser bore to the suppresser chamber.

Provided herein are shaped charges for focusing a fluid mass and related methods of using the shaped charges for disruption of an explosive target with a spherical projectile. The shaped charge comprises a plastic shell having a special geometric shape configured to support a shape-conforming explosive. A cylindrical plastic body has an interior volume for containing a fluid and the plastic shell. The plastic body closed distal end has a geometric shape that is substantially matched to the shape of the plastic shell. Metal spherical projectiles having an outer layer of metal selected to have an effective density matched to the fluid provide advantageous target disruption capabilities.

Provided herein are shaped-charges for focusing a filler, such as a fluid mass, and related methods of using the shaped-charges for disruption of an explosive target. The shaped-charge comprises an attenuating body positioned and configured to attenuate rarefaction waves to increase filler, including a fluid mass, explosively driven out of the container toward a target while also maintaining and enhancing fluid jet integrity. To further control impact and impulse forces on a target, additional layers may be used, including a foam layer and a jet-clipping layer positioned between the shaped-charge and the target surface. Also provided are propellant driven liquid disrupters having special attenuating bodies to improve liquid jet column characteristics.
