The Phenomenology of Interround Communication and Techniques for Prevention
Abstract
Examination of large scale munitions propagation tests indicated that the mechanisms by which detonation and violent reaction propagate between munitions and through stacks are inadequately understood. Experimental data were obtained with respect to interround propagation and with respect to munition response to fragment impact and deformation. The data are consistent with the assumption that ignition is caused by individual fragment impacts creating a stress level in the explosive which exceeds some critical value. The violence of the post ignition reaction was found to be proportional to the delivered areal impulse density, and is consistent with assuming that the reaction violence is proportional to the deformation of the explosive. Since the yield strength of the explosive is far less than that of the casing, the warhead casing essentially controls the violence of reaction.
