A Safety, Quality and Cost Effectiveness Study of Composition A-3 Press Loading Parameters (II)

Abstract

This report presents further details of a safety, quality and cost effectiveness study of loading gun ammunition with Composition A-3 explosive previously reported in NWSY TR 76-1. Processing parameters were required to increase gun firing safety and increase explosive load quality using material with a bulk density of less than 0.81 g/cc at the lowest possible cost. The temperature and pressing efforts were investigated and production processing parameters were established. The problem of explosive cracking after temperature cycling was traced to the new type waxes being used in the manufacture of the Composition A-3. The ram configuration, pressing pressure, increment weights and sizes were optimized for limited range of temperatures.
