摘要
旋转冲压发动机是一种没有叶片和活塞的基于冲压压缩技术的新概念发动机,气体的压缩主要是通过运动激波压缩来完成,通过对运动激波压缩过程的理论分析并与发动机冲压转子盘腔冷态流场进行数值模拟结果进行对比,印证了旋转冲压发动机中运动激波压缩假设的正确性．计算结果同时表明,旋转冲压发动机中的运动激波压缩效果和性能良好．
The rotated ramjet is a new conceptive engine based on the ram-compressed technology, which has no blade and no piston but has a ram-compressed rotor. The air compressed mainly by the moving shock wave. The theory of the moving shock wave compressing and the no heated flow field on the ram-compressed rotor disc cavity have been analyzed and the result of numerical calculated with three-dimensional steady RANS equations confirm the guess on the air was ram-compressed in the rotor by the moving shock wave. Results show that the effect of ram-compressed is availability.
