| 摘 要： | 采用一维气动分析和三维流场数值模拟两种方法,对超声速二元进气道的性能进行了研究.研究结果表明,超声速进气道侧向膨胀对进气道性能影响显著,侧向膨胀使进气道喉部马赫数增大,扩张段正激波强度增大,进气道总压恢复系数和流量捕获系数都减小.

| 关 键 词： | 进气道 侧向膨胀 总压恢复系数 流量捕获系数 |

| Abstract: | In order to analyse the performance of supersonic inlet,one-dimensional aerodynamic analysis and three-dimensional numerical simulation are used.The results show that expansion in width cannot be neglected.Expansion in width can lead to the increase of inlet throat Mach number,which results in the decrease of inlet total pressure recovery and flow capture efficient. |

| Keywords: | inlet expansion in width total pressure recovery capture coefficient |
