An important property of a solid explosive is its impact sensitivity. This determines a minimum force (or energy) which is needed for initiation of detonation. To measure impact sensitivity one can apply conventional drop weight test. The result of such experiment, the h50 value (cm), determines a minimum drop height which is needed to reproduce 50 % of successful trials. Previously, a number of the quantitative structure-activity relationships (QSAR), including very complex artificial neutral networks, were developed to predict the h50 values. These models are based on estimation of the molecular features (topological, electrostatic potential, volume, orbital information, etc) and provide satisfactory results.
