摘　　要：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。A new type of projectile launch technoloygy -ram accelerator is introduced in this paper. Based on the interacting complex shock flowfields of the ram accelerator, a high resolution TVD finite volume scheme has been constructed for solution of the N-S equations. Some computed results are in good accord with experimental results. Computed flow fields are given in detail. This paper gives the theoretical guide to design the non-reacting flow field test.
