Analytical Model for High Explosive Munitions Storage
Abstract
Analytical models and subsequent computer codes have been developed for predicting peak overpressure, positive unit impulse, the distribution and impact velocity of bomb fragments, crater dimensions and ejecta thickness from the detonations of typical bomb stacks used by the Air Force. These models consider aboveground barricaded stacks with an equivalent net weight high- explosive range of 10 to 500 tons of TNT. The peak overpressure and impulse from a detonation are obtained by modifying the known results of a bare hemispherical charge to take into account the stack and barricade geometries and the interaction effect of bombs. Fragment dispersion patterns are predicted by combining experimental results for single bombs and using the trajectory equations for the motion of a steel fragment in air. By using basic principles and experimental data, crater and ejecta dimensions are predicted. Based on output from the computer codes, illustrative examples are given together with recommendations for future tests to obtain needed data. Programs for optimizing munition storage areas are also suggested.
