Abstract: A purpose of this study was to provide an enhanced understanding of typical impact and aerodynamic behaviour of segmented rod projectiles. A range of designs was examined by computational modelling. In all cases the segments have been treated as a dynamically changing configuration of free-flying bodies separated at launch. The paper highlights difficulties of this approach showing that, prior to impact, the segments rapidly lose alignment, which reduces effectiveness of penetration. Investigation of alternative design concepts is recommended.
