Abstract

Provided is a multi-configuration transportable demolition pouch that includes a cruciform shaped section of fabric with a central explosive containing area and four trimmable flaps, a fastener on each of the flaps, a strap accepting slit, a first and a second strap, a fabric lid and priming hole, and one or more energetic device that can be selected based on desired blast footprint. The pouch can be trimmed when using smaller quantities of explosives to reduce its footprint and facilitate ease of carrying and emplacement. The device has attachment features to aid in transport and to provide proper spacing and attachment points for demolitions and breeching techniques involving multiple charges. The pouch provides components to allow for blast footprint alteration and for water tamping to reduce blast effects to nearby personnel, as well as to increase the efficiency of the explosive charge.

First claim

1 . A multi-configuration transportable demolition pouch comprising:
a cruciform shaped section of fabric comprising a central explosive containing area and four trimmable flaps; a fastener on each of said trimmable flaps; a strap accepting slit positioned at a junction between each of said trimmable flaps and said central explosive containing area; a first and a second strap; a fabric lid comprising a fastener and a centered priming hole; and a first energetic device comprising a packed explosive, a sheet explosive, and a detonation cord wrapped around and secured to said sheet explosive; or a second energetic device comprising, in order, a packed explosive, a first sheet explosive, a wave shaper, a second sheet explosive, and a detonation cord wrapped around and secured to said second sheet explosive; wherein said first or said second energetic device is placed in said central explosive containing area, said trimmable flaps are trimmed to secure said first energetic device in said central explosive containing area in a pouch configuration, said fabric lid is positioned on top of said trimmable flaps, said detonation chord is passed through said centered priming hole, and said straps are passed through said strap accepting slits and tightened; wherein said first energetic device, when detonated, provides a central detonation point causing hemispherical detonation wave propagation to produce an expanding blast zone; and wherein said second energetic device, when detonated, said wave shaper creates an interrupted hemispherical detonation wave that causes detonation propagation to travel to outer edges of said packed explosive to produce a reduced footprint blast zone.

2 . The multi-configuration transportable demolition pouch of claim 1 , wherein said pouch further comprises one or more attachment features.

3 . The multi-configuration transportable demolition pouch of claim 1 , wherein said wave shaper can be immersed in water to provide water tamping to reduce blast effects.
