Transient Analysis Method for HEMi Sabot Structural Design

Abstract

The High Energy Missile (HEMi) design objective is to defeat 1000 mm of roll hardened armour with a weapon that measures less than 1.2 m long in its stored configuration. An innovative penetrator concept utilizing segmented penetrators was developed. To validate the hydrocode predictions of the penetrator performance, an experimental program to launch prototype segmented penetrators in a two-stage light gas gun was prepared. Acceleration of the penetrator to hypervelocity speeds requires a sabot that can withstand the high g-forces generated by the expanding gas and the inertia of the penetrator. This document discusses the finite element analysis strategy that was developed to calculate sabot stresses and displacements under static and transient conditions.
