Abstract

In order to analyze the influence of exceeding the initial room temperature criterion on a missile motor under conditions of high and low temperatures, three-dimensional solid for every part of the first stage motor was simplified and modeled by the CFD method. After considering heat conduction, convection and radiation, the stationary simulation calculation was conducted by the fluid-solid coupled heat transfer method to obtain the temperature distribution at different temperatures in severe field environment and theoretical basis used for adjusting the initial room temperature criterion. Through simulating the model described in Reference [2], it could be determined that the results of the simulation are in accordance with that of the experimental data. Using the CFD method and the fluid-solid coupled method can provide both reference and basis for adjusting the temperature of missile motor propellant.
