In this paper the problem is studied adopting finite difference method for the case of a rocket powered missile. Temperature distribution tables are given through quadrature experiments, and the results fit the actual measured values very well. The results also show that to ensure the launching security of rocket powered missiles having warhead charge critical temperature close to about 60?℃, the designer can select appropriate heat insulation structural parameters.展开更多
