The objective of this Phase I effort is to establish the feasibility and performance benefits of incorporating a traveling charge to achieve maximum gun launch energy while minimizing peak pressure and acceleration loads. The effort involves three primary tasks:(1) Preliminary design and analysis of single ram and double ram projectile, traveling charge, and fixed charge designs;(2) Selection of applicable traveling charge propellant compositions and corresponding grain designs; and(3) Characterize interior ballistic performance of single ram and double ram traveling charge configurations for variations of traveling charge to fixed charge mass ratios and for various delay times between ignition of the fixed charge and ignition of the traveling charge. Should the effort result in developing a traveling charge approach that can be applied to existing and/or future Navy gun systems, significant range performance increases could potentially be realized without imposing additional structural demands on either the gun system or the projectile.
