| 摘 要： | 对某型冲压发动机二元混压式进气道进行了三维数值模拟。研究了不同来流及背压条件对进气道性能的影响,以及弹体气动性能对进气道工作特性的影响。结果表明,在宽广的飞行马赫数和空域范围内,进气道的性能差异很大;对于单独设计的进气道,安装在弹体上以后,其性能会出现明显下降;弹体附面层隔槽大小及轴向安装位置会对进气道性能产生较大影响。根据计算结果,可以为该进气道提供实验方案,并为其装配提供参考数据。

| Abstract: | Three-dimensional flow of a two-dimension ramjet inlet was simulated numerically.The effect of different work condition and flow field of the missile on the performance of the inlet was analyzed.It is indicated that inlet performance has large difference in wide flight range;it will descend obviously after installation and behaved differently based on installation position and boundary layer interval.The result can be used to set test and installation scheme. |

| Keywords: | solid-ramjet two-dimension inlet numerical simulation boundary layer interval |
