Hydrocode Computations and Experimental Investigations of Explosive Staged Shaped Charge Devices

Abstract

A staged shaped charge design is under investigation at the BRL. The device makes possible coherent shaped charge jets from extremely narrow angle liners. This is brought about through the explosive staging technique where the energy of the explosive is stored momentarily as kinetic energy of a metallic conical shell originally in contact with the high explosive, and then, delivered in a predetermined manner to an inner jetting metallic shaped charge liner. The paper presents the physical design of the staged shaped charge and its principal of operation. The staging mechanism and liner collapse are describe by both analytic and hydrocode approaches (HEMP). Experimental results are presented through radiographs flashed directly through the detonating charge showing the collapse process, jet formation, and early jet motion. These are compared directly with grid overlays calculated by HEMP. Results are presented for three inner liner materials; nickel, copper and aluminum.
