Abstract:
A liquid disrupter for deactivating a bomb comprising:a main elongated hollow barrel having a rigid cylindrical body with an inner chamber, a closed rear end and an opened front end closed with a front frangible seal; a channel member having a bore engaged by said barrel, said channel member being securely attached to said barrel; at least two recoil channels equally peripherally spaced about said barrel, said recoil channels having a first end extending through said barrel cylindrical body and opening inside said barrel inner chamber at a section thereof intermediate said front and rear ends, and a second end rearwardly opening out of said channel member and closed with rear frangible seals, said recoil channels radially outwardly and rearwardly extending through said barrel cylindrical body and said channel member from said first to said second ends; a remotely selectively controlled trigger member operatively mounted to said barrel; wherein in operation, an explosive charge is to be placed inside said barrel inner chamber near said rear end and connected to said trigger member, and said barrel body inner chamber and said recoil channels are to be filled with fluid, and wherein upon the explosive charge exploding when it is detonated by said trigger member, a portion of the fluid is ejected at high velocity frontwardly out of said barrel front end, rupturing said front frangible seal, to puncture the bomb outer shell and deactivate the bomb inner detonating components, and another portion of the fluid concurrently engages said recoil channels, rupturing said rear frangible seals, to be rearwardly ejected out of said channels, which at least partly counteracts the rearward recoil resulting from the explosive charge projecting the water frontwardly out of said barrel;wherein each said recoil channel includes a first and a second channel sections, said first channel section extending through said barrel and said channel member in a radially outwardly and rearwardly inclined fashion relative to said barrel, and said second channel section being a recoil tube securely attached to said channel member and rearwardly projecting from said first channel section, said recoil channel second end being located at the rear end of said recoil tube; andwherein each said recoil tube is provided with transverse blades at its rear end, for wide angle dispersal of the fluid jet being ejected out of said recoil tubes.
