Launch Survivability Analysis of On-board Components of the Extended Area Protection and Survivability (EAPS) Projectile System

Authors: Michael M. Chen; ARMY RESEARCH LAB ABERDEEN PROVING GROUND MD WEAPONS AND MATERIALS RESEARCH DIRECTORATE
 
Abstract: This report focuses on the ability of on-board electronics generally required for precision projectiles to survive pressure waves that occur in early combustion phase for most propelling charges because of pressure imbalance in the chamber. The modeling of pressure waves was achieved by a deterministic transient excitation followed by a stochastic approach. The responses of the on-board electronic components were found to be significant when pressure waves were taken into account.
