An analytical study was conducted to determine the feasibility of using layers of phase-change materials to control gun tube temperatures. A mathematical model of the process was developed and programmed for numerical evaluation. Results of a parametric study were used to determine the optimum characteristics of the phase-change layer. A brief literature survey was made to determine the thermal property-values of materials in which phase-change occurs in the desired temperature range. Two materials were chosen for further numerical study. The results of this investigation shown that gun-tube temperature control with a phase-change layer is thermally feasible.
