介绍一种新型发射技术──冲压加速器技术。根据冲压加速过程中复杂激波系的流场特点，构造了有限体积的ＴＶＤ格式，用于求解Ｎ－Ｓ方程。计算结果与试验结果相一致，给出详细的流场谱图。为冲压加速器的冷态试验提供有益的指导。
Introducing a new launch technology - stamping accelerator technology. According to the characteristics of the flow field of complex shock wave during the acceleration process, a finite volume TVD format is constructed for solving the N-S equation. The calculated results are consistent with the experimental results, giving a detailed flow field spectrum. Provide a useful guide for cold test of stamping accelerator.
