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 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.

The invention discloses an inflammable and explosive explosive emergency destruction device, which comprises a base, a transmission shaft is rotatably connected to the upper end surface of the base, and an overhead device is arranged on the transmission shaft, and the overhead device can be connected to For the limit plate on the transmission shaft, the present invention uses a hemispherical cover and two quarter-ball covers to change the position to form a closed sphere to isolate flammable and explosive materials from the external environment to ensure the safety of the surroundings. The overhead mode of the destruction structure converts the vertical vibration generated by the explosion into the power of horizontal upward and reverse rotation, and uses multiple sets of spring structures to buffer, effectively protect the ground from damage, and performs water injection treatment on the interior of the closed sphere. Affects or destroys the conditions required for the original object to react, preventing secondary damage.

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.

A cap for an explosive water charge may be fixed to a collapsible water bottle by threading internal threads of the cap onto external threads of the water bottle. The cap also may be fixed to a water bottle by engaging a lip on the water bottle with lip grabbers on the cap. The cap is configured to hold a blasting cap and two different sizes of tubes of energetic material.

A method for cutting, in a non-through manner, a body of a thruster of an aerospace vehicle, water jets, the method including a plurality of passes of a high-pressure water jet along the same cutting path extending across the external perimeter of the thruster body, the cutting path describing a closed loop circuit, and each water jet pass starting from a starting point located on the cutting path and stopping just after returning on the starting location. The starting point of each high-pressure water jet pass is different from the starting points of the other water jet passes.
