US12523456 - Device, system, and method for transport and activation of a two- part explosive

A system for delivering and activating a two-part explosive may include an unmanned vehicle and/or an elevated structure, and a two-part explosive device. The device may include a container that is attached to, and releasable from, the unmanned vehicle or elevated structure. The container may contain an unsensitized explosive enclosed in a casing and and a sensitizing agent adjacent to the casing. The device may include an opening mechanism positioned at least partially within the container and adjacent to the casing. The opening mechanism may open the casing and expose the unsensitized explosive to the sensitizing agent, forming the two-part explosive in response to the container being released from the unmanned vehicle or elevated structure. The device may include a detonator inside or attached to the container. The detonator may trigger ignition of the two-part explosive after the unsensitized explosive is exposed to the sensitizing agent.

Claim 1

1 . A system that delivers and combines a two-part explosive, comprising: an unmanned vehicle; a container that contains the two-part explosive, wherein: the container is attached to, and releasable from, the unmanned vehicle; and the two-part explosive comprises: an unsensitized explosive in a casing that encloses the unsensitized explosive; and a sensitizing agent adjacent to the casing; an opening mechanism positioned at least partially within the container and adjacent to the casing, wherein the opening mechanism opens the casing and exposes the unsensitized explosive to the sensitizing agent in response to the container being released from the unmanned vehicle, the opening mechanism comprising a spring-loaded pin positioned such that, as the spring-loaded pin deploys it punctures or cuts the casing, wherein the spring-loaded pin is deployed in response to the container being released from the unmanned vehicle; and a detonator inside or attached to the container, wherein the detonator triggers ignition of the two-part explosive after the unsensitized explosive is exposed to the sensitizing agent. an unmanned vehicle; a container that contains the two-part explosive, wherein: the container is attached to, and releasable from, the unmanned vehicle; and the two-part explosive comprises: an unsensitized explosive in a casing that encloses the unsensitized explosive; and a sensitizing agent adjacent to the casing; an opening mechanism positioned at least partially within the container and adjacent to the casing, wherein the opening mechanism opens the casing and exposes the unsensitized explosive to the sensitizing agent in response to the container being released from the unmanned vehicle, the opening mechanism comprising a spring-loaded pin positioned such that, as the spring-loaded pin deploys it punctures or cuts the casing, wherein the spring-loaded pin is deployed in response to the container being released from the unmanned vehicle; and a detonator inside or attached to the container, wherein the detonator triggers ignition of the two-part explosive after the unsensitized explosive is exposed to the sensitizing agent. the container is attached to, and releasable from, the unmanned vehicle; and the two-part explosive comprises: an unsensitized explosive in a casing that encloses the unsensitized explosive; and a sensitizing agent adjacent to the casing; an unsensitized explosive in a casing that encloses the unsensitized explosive; and a sensitizing agent adjacent to the casing; an opening mechanism positioned at least partially within the container and adjacent to the casing, wherein the opening mechanism opens the casing and exposes the unsensitized explosive to the sensitizing agent in response to the container being released from the unmanned vehicle, the opening mechanism comprising a spring-loaded pin positioned such that, as the spring-loaded pin deploys it punctures or cuts the casing, wherein the spring-loaded pin is deployed in response to the container being released from the unmanned vehicle; and a detonator inside or attached to the container, wherein the detonator triggers ignition of the two-part explosive after the unsensitized explosive is exposed to the sensitizing agent.
