Voltage induced porosity in insensitive munition

A method of selectively increasing the sensitivity of an insensitive munition by inducing porosity or Joule heating in munitions assembly comprising a power source, an explosive apparatus and a fuze apparatus wherein the explosive apparatus contains a sensitized main explosive composition comprising a secondary explosive and a sensitizing agent. As a result, the otherwise insensitive munition is rendered sensitive to a propagating wave shock by approximately 10 to 25%. To this end, a voltage is applied across the main conductive explosive composition within the insensitive munition. Voltages above certain thresholds cause the decomposition of the explosive material or conductive binder, which leads to an increase in porosity, and therefore the shock sensitivity.

Chemical agent delivery receptacle with reusable digital control cartridge
11243057 · 2022-02-08 · ·

A digitally controlled hand-tossable explosive delivery receptacle comprises a ruggedized reusable compartment enclosing a digital circuit and a disposable cartridge holding one or more explosive chemical agents and a primer. The disposable cartridge is configured to be mounted to the ruggedized reusable cartridge, and a high-strength bulkhead incorporated into the reusable or disposable compartment that separates the digital circuit from the chemical agents. The reusable compartment is sufficiently ruggedized to withstand the ignition of the primer and the detonation of the chemical agents to be reused with one or more additional disposable cartridges. In one implementation, the delivery receptacle uses a commercial airbag initiator as the primer, which is arranged in relation to the one or more chemical agents so that when the initiator is activated, it generates a pressure wave that expels the one or more chemical agents from the grenade.
