Abstract
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.
Claims10
A dearmer, comprising:
- a blank cartridge being configured to create propulsion gas;
- an air-tight insert being disposed around the blank cartridge and conforming to an exterior profile of the blank cartridge;
- an EOD projectile being disposed adjacent a base of the blank cartridge;
- an outer sleeve being disposed around the air-tight insert;
- and
- a converging-diverging nozzle being disposed adjacent an end of the blank cartridge that is opposite the base of the blank cartridge and fixed to the outer sleeve,
- wherein the converging-diverging nozzle is configured to receive the propulsion gas and thereby propel the dearmer toward a target to dearm the target.
