Abstract

A numerical analysis has been performed in this study to predict thermal behaviors of combined weapon systems in a large environmental tester. Also, temperature distributions of the materials of the system have been measured for the experimental conditions. The calculated thermal flow characteristics and the measured temperature distributions of the materials for the weapon systems have been analyzed to prepare for field tests in the environmental tester. The boundary conditions of the analysis are composed of inlet and outlet conditions of the environmental tester with various pressures and the limit of low temperature of -25$^{\circ}$C. The soaking time of the system in the environmental tester has been obtained by developed programs in this study to carry out the experiment in the predicted conditions.
