Abstract: Methods, systems, and devices for an area-denial munition configured for self-neutralization of an explosive ordnance. In one or more embodiments the munition including a housing including a chassis defining one or more openings such that the housing is an at least partially open structure exposing an interior to an ambient environment. In various embodiments the munition includes a detonation module including a detonation initiator and a deflagration module including a deflagration initiator coupled with a pyrotechnic primer, and munition control circuitry. In various embodiments the munition control circuitry receives instructions to deflagrate the explosive ordnance and instructs the deflagration module to activate the deflagration initiator. In various embodiments, the deflagration initiator causes a deflagration of the explosive ordnance for self-neutralization of the munition resulting in safe destruction of the munition's explosive charge and control electronics.

Abstract: A capacitive discharge unit (CDU) for detonating an explosive in response to a control signal comprises a set of CDU components, including an exploding foil initiator (EFI), a trigger circuit, a firing capacitor, and an insulated-gate bipolar transistor (IGBT) firing switch. In various embodiments the components are arranged on a board for mechanically and electrically supporting the components in an ordered arrangement along a CDU axis where the CDU having an axial length defined by the ordered arrangement of two or more of the EFI, the firing capacitor, and the IBGT firing switch, wherein the trigger circuit is offset from the CDU axis such that the trigger circuit does not contribute to the axial length.
