Webbguide for the design and application of reactive material liner and shape charge. 2. Experiment Setup and Simulation Method 2.1. Experiment Setup In this research, a … Webb29 juni 2015 · The shaped charge or “jet” perforator uses a small amount of high explosive and a carefully shaped case and liner to create a focused pressure punch that is highly … A typical device consists of a solid cylinder of explosive with a metal-lined conical hollow in one end and a central detonator, array of detonators, or detonation wave guide at the other end. Explosive energy is released directly away from (normal to) the surface of an explosive, so shaping the explosive will concentrate the explosive energy in the void. If the hollow is properly shaped (… early warning movie
