Numerical Analysis of Flow Distribution for Combined Weapon System in Environmental Tester

Abstract

Thermal behaviors of combined weapon systems have been analyzed in this study by developed computational programs. Also, temperature distributions of the materials of the system have been measured for the experimental conditions. Field tests in the large environmental tester have been prepared by the calculated thermal flow characteristics and the measured temperature distributions of the materials for the weapon systems. The boundary conditions of the analysis are composed of inlet and outlet conditions of the environmental tester and the limit of low temperature of −32°C. The soaking time of the system including a fuel tank and a battery in the environmental tester has been obtained by developed programs in this study to carry out the experiment in the predicted conditions.
