Abstract: In this paper,the finite element method which was extensively and effectively used was also applied to predict the transient temperature field of the composite nozzle in a cylindrical solid rocket motor. The differences of convective heat transfer coefficient along the nozzle axix and the anisotropy of the material were considered in the computation. The program can be easy generalized. The method and model for computation provided in this paper is practical in engineering.
