We offered the numerical computation method in this process by using the fluent of CFD （ Computational Fluid Dynamics）software. Based on the specific examples, we carried out the computation of the model＇s drag coefficient, lift coefficient and pitching moment with its launching process. The computation results agree with the results of the experiment and the error between them is less than 10%. It shows that this computation method is viable and can be used in the system design, and the analysis of missile motion and basic structure intensity.展开更多
