Overview of Analysis and Test Support for the MUNITIONS SURVIVABILITY TECHNOLOGY Program

摘要

The Munitions Survivability Technology(MST) program was initiated by the Defense Ammunition Logistics Activity to develop a rapidly deployable system of fragment barricades combined with lightweight fire-inhibiting blankets, with guidelines for their use to prevent or reduce propagation of explosions and fire between stacks of Army munitions. In order to ensure the maximum effectiveness of such systems, the U.S. Army Research Laboratory has undertaken a program to elucidate relevant propagation mechanisms, enhance predictive techniques for propagation, and develop data required for the evaluation of the system to be fielded. Available resources include the FRAGPROP model for predicting propagation of detonation and burning reactions between ammunition stacks, the FRAGGEN model for predicting fragmentation of items that are not characterized in arena tests, existing data on gun propellant and rocket motor vulnerability to fragment attack, analyses and test procedures developed in conjunction with the Navy's HIGH-PERFORMANCE MAGAZINE program, and data from hazard classification tests. The MST program is divided into four broad areas: (1) fragment propagation, (2) crushing propagation, (3) fire propagation, and (4) ammunition site design criteria. Although much of this work is still in progress, considerable success has been achieved.
