Abstract

An explosive disruptor includes a first jacket having joined inflatable members. The inflatable members are adapted to be filled with a gas. A second jacket is surrounded by and coupled to the first jacket. The second jacket has an outer radial wall, an inner radial wall spaced apart from the outer radial wall, and two end walls coupled to opposing axial ends of the outer radial wall and the inner radial wall. A first volumetric region is defined between the outer radial wall, the inner radial wall, and the two end walls. A second volumetric region is defined by the inner radial wall. The first volumetric region is sealed and adapted to be filled with a liquid. An explosive material is disposed in the second volumetric region. A blasting cap is in contact with the explosive material.

Claims

1. An explosive disruptor, comprising:

a first jacket including a plurality of inflatable members arranged at a radial periphery thereof, each of said inflatable members disposed between two others of said inflatable members and joined to each of said two others along a length of said first jacket, said inflatable members adapted to be filled with a gas;

a second jacket being surrounded by and being coupled to said first jacket, said second jacket includes an outer radial wall, an inner radial wall spaced apart from said outer radial wall, and two end walls coupled to opposing axial ends of said outer radial wall and said inner radial wall, wherein a first volumetric region is defined between said outer radial wall, said inner radial wall, and said two end walls, and wherein a second volumetric region is defined by said inner radial wall, said first volumetric region being sealed, said first volumetric region adapted to be filled with a liquid;

an explosive material being disposed in said second volumetric region; and

a blasting cap in contact with said explosive material.

2. The explosive disruptor as in claim 1, wherein said first jacket is cylindrical.
