The U.S. Army Research Laboratory ARL obtained a sample of powder metal-lined nonprecision shaped charges from Halliburton Energy Services located in Alvarado, TX. These shaped charges, designated as the 4 58-in PM OMNI, are designed and manufactured for use as oil-well or gas-well perforators. The agreement with Halliburton Energy Services involved a complete study of these rounds. They were being investigated as a potential shaped charge to be used in the controlled detonation, containment, and decontamination of chemical munitions by the U.S. Army Garrison Directorate of Safety, Health, and the Environment DSHE at Aberdeen Proving Ground APO. ARL is interested in charges of this type due to their design for optimum performance at short standoff, the short charge length and head height, the fact that the charges are inexpensive, and their potential application as precursor charges against specialized targets. The authors also have an interest in modeling the penetration of a powder-metal jet. Thus, the penetration standoff data will provide experimental data to verify a penetration model. This study is the subject of this report.
