ABSTRACT:
A blast focusing technique for producing high pressure on a ground plane, in which a right circular cylinder of explosive material is positioned adjacent the ground plane with the cylinder axis orthogonal to the ground plane. The cylinder is simultaneously detonated at both ends by detonators disposed on the cylinder axis at each end of the cylinder.
