摘　　要：采用计算流体力学方法开展了超燃冲压发动机流场二维及三维数值仿真,获得了发动机流场结构及流动细节。探讨了二维简化计算的适用性及不足。通过对发动机各部件受力的分析,得到了发动机初步性能,并就支板及凹腔的减阻设计提供了一些参考。The 2D and 3D numerical simulations of a scramjet were conducted respectively with computational fluid dynamics （CFD） method. The flow field structure and flow detail of a scramjet were obtained. The applicability and shortage of the 2D simplified calculation were discussed. The preliminary performance of the engine was achieved by means of force analysis on every part of the engine. Some additional references about drag reduction design for the strut and cavity are provided in this paper.
