Abstract
An apparatus for blast suppression involves forming a foam barrier in proximity to a bomb or other suspicious device. The foam is maintained in position by a containment structure which is inflated and kept in an inflated state by the foam used to form such barrier. Various containment structures are disclosed for suppression of compression waves and combustion effects caused by an explosive event.
Claims14
An apparatus for suppressing a blast from an explosive device comprising:
- a) a foam generating unit comprising:
- i) a vessel having a top, a bottom, an outer surface, an internal chamber, at least one input port and at least one output port;
- and
- ii) a siphon tube having an upper end, a bottom end and a length, wherein said upper end is connected to said output port, and said siphon tube is vertically disposed within said vessel;
- b) a containment structure having an outer surface, and inner surface and an internal void, wherein said containment structure has an inlet orifice extending from the outer surface of said containment structure into said internal void;
- and
- c) a conduit extending from said at least one output port of said vessel to said inlet orifice of said containment structure.
