Abstract

A novel shaped charge device that produces a hollow cylindrical jet capable of creating a hole in a target larger than the overall diameter of the device. In the conical family of axisymmetric circular linear shaped charge liners (Conical, Tulip, and Trumpet), this novel swept conical-like profile shaped explosive device produces a large diameter stretching hollow cylindrical jet and corresponding slug. The hollow jet is formed by peripherally initiating a high explosive (HE) that collapses the circular linear liner into the hollow cylindrical jet. The precision of the circular simultaneous peripheral initiation of the HE billet is accomplished by the use of a novel Circular Precision Initiation Coupler (CPIC). This CPIC uses a single point initiation to create a simultaneous peripheral detonation of the HE billet that collapses and drives the swept liner into a high speed stretching hollow cylindrical projectile, or more commonly called a jet in the industry.
