Linear explosive charge with constant detonation velocity and synchronous booster charges

摘要

A linear explosive charge with constant detonation velocity comprising, a plurality of separate similar sticks that can be axially coupled into a long linear substantially rigid assembly. Each of the sticks includes a helical winding of linear explosive cord on its outer surface, the ends of the cord are coupled to the ends of the cord on adjacent sticks, so as to carry the detonation of the cord from one stick to the next. Separate booster explosive charge units are coupled into each of the junctions between sticks, to provide additional explosive units which are synchronously detonated by the passage of the cord detonation from stick to stick.
