Apparatus and methods for disrupting/disabling explosive ordnance

Explosive devices may be formed from hollow members filled with explosive materials. The hollow members may be made of mating halves that are packed or loaded with explosive material prior to the mating halves being joined together. In some exemplary aspects, the hollow members are placed in fluid-filled containers such that the explosive reaction creates a wave of fluid that impacts a target. Components of the devices may be COTS items and items that may be manufacture with 3D printers.

METHODS AND DEVICES METERING AND COMPACTING EXPLOSIVE POWDERS

A powder compaction device is disclosed. The device has a drive motor operable connected to a compaction rod that moves through a loading platform to a cartridge holding platform. A powder loading station is positioned below the loading platform and above the cartridge holding platform. The compaction rod moves through the powder loading station, which loads a predetermined volume of propellant powder into one or more reliefs defined in the compaction rod. The cartridge holding platform has a removable cartridge fixture designed to receive an ammunition cartridge to be loaded and compacted with propellant powder. The propellant powder is released into the cartridge fixture from the reliefs as the compaction rod passes a funnel defined at an upper end of the fixture. After releasing the powder, the compaction rod continues into an interior chamber of the fixture to compact the powder contained therein.

SHAPED POWER CHARGE WITH INTEGRATED INITIATOR

A power charge for actuating a wellbore tool. Combustion of the power charge generates gas and corresponding gas pressure within the wellbore tool and the power charge and wellbore tool are configured for providing a path to an expansion chamber for the gas pressure. A body of the power charge may have the shape of a regular polygonal cylinder, thus defining flow-paths for the expanding gas. The power charge may include a cylinder of energetic material and an interior space formed within the energetic material and configured for receiving an igniter and/or ignition material. Ignition of the igniter or ignition material results in combustion of the power charge.

A de-coupling mechanism includes a link slidably received in a link aperture of a bracket. A pin is slidably received in a pin bore of the link and a receiving bore of the bracket. A first block is connected to the bracket and includes an initiator receiving passage in communication with the pin bore. An initiator is positioned in the initiator receiving passage and retained against a connecting passage edge and oppositely contacts an end face of a cap connected to the first block. A second block connected to the bracket includes a longitudinal channel having a channel diameter larger than a pin diameter so the pin is freely displaceable into the longitudinal channel. An end face of a retaining cap is connected to a second block end wall. The retaining cap includes a stepped portion having a step diameter smaller than the channel diameter and the pin diameter.

ADJUSTABLE STAND FOR HOLDING A LIQUID EXPLOSIVE
20170299348 · 2017-10-19 ·

A low-cost, reliable and easy to use kit for neutralizing surface exposed landmine and unexploded ordnance for humanitarian demining is based on a liquid fuel and a solid/soluble fuel. Both fuels are premeasured in separate, sealed containers. The addition of a small quantity of solid/soluble fuel into the liquid creates an explosive. The resulting mixture is capable of detonating with a standard No. 8 blasting cap. The solid/soluble fuel can be in the form of a powder, tablet, or its saturated solution in water. The solid/soluble fuel is hexamethylenetetramine. The liquid fuel, nitromethane, is provided in premeasured quantities. User is provided instructions for choosing the appropriate quantity of liquid fuel, the corresponding solid/soluble fuel required, the method of mixing, placement and detonation of the kits. Also disclosed is a simple wooden stand to hold the bottle of explosive in place. A special fuel, liquid 2-ethylhexylnitrate, is provided to desensitize the mixed and sensitized explosive.
