US12442616 - Half pipe disrupter

Provided herein are mass focusing shaped charges and related methods useful for disrupting targets in either underwater or on land. The mass focusing shaped charges comprise an explosives shell having an explosives shell surface, wherein at least a portion is curved and defines an inner volume configured to contain an inner volume of fluid or a metal liner. A distal body is comprising a SMART material is positioned between the inner volume of fluid and a to-be-disrupted target. A conformable layer of explosives conforms to at least a portion of a surface of the explosives shell, the conformable layer of explosives configured for explosive initiation by a detonator. Upon explosive initiation the inner volume of fluid or metal liner is forcefully ejected to form a fluid or metal jet in a direction through the distal body and toward the target.

The patent describes a mass focusing shaped charge designed to disrupt targets using a combination of an explosives shell, a SMART material distal body, and a conformable layer of explosives. Upon detonation, the inner volume of fluid or metal liner is forcefully ejected, creating a jet directed at the target for effective disruption.

Claim 1

A mass focusing shaped charge to disrupt a target comprising: an explosives shell having: an explosives shell surface having an inside surface and an outside surface; an explosives shell sectioned profile that is at least partially curved; one or more symmetry planes; an inner volume defined by the explosives shell inside surface configured to contain an inner volume of fluid; a distal opening; a distal body connected to the explosives shell distal opening to close the inner volume and contain the inner volume of fluid, wherein the distal body comprises a SMART material that is positioned between the inner volume of fluid and the target; a fluid body, wherein the explosives shell is immersed in the fluid body; a conformable layer of explosives that conforms to at least a portion of a surface of the explosives shell, the conformable layer of explosives configured for explosive initiation by a detonator; wherein upon explosive initiation the inner volume of fluid is configured to implode and form a fluid jet that is forced in a direction through the distal body toward the target. an explosives shell having: an explosives shell surface having an inside surface and an outside surface; an explosives shell sectioned profile that is at least partially curved; one or more symmetry planes; an inner volume defined by the explosives shell inside surface configured to contain an inner volume of fluid; a distal opening; an explosives shell surface having an inside surface and an outside surface; an explosives shell sectioned profile that is at least partially curved; one or more symmetry planes; an inner volume defined by the explosives shell inside surface configured to contain an inner volume of fluid; a distal opening; a distal body connected to the explosives shell distal opening to close the inner volume and contain the inner volume of fluid, wherein the distal body comprises a SMART material that is positioned between the inner volume of fluid and the target; a fluid body, wherein the explosives shell is immersed in the fluid body; a conformable layer of explosives that conforms to at least a portion of a surface of the explosives shell, the conformable layer of explosives configured for explosive initiation by a detonator; wherein upon explosive initiation the inner volume of fluid is configured to implode and form a fluid jet that is forced in a direction through the distal body toward the target.
