| 摘 要： | 结合质量吸除方案,对超声速混压式进气道进行了起动耦合型面设计,并采用CFD数值模拟对进气道的总体性能进行了对比分析。研究结果表明该方案具有以下优点:1)可以提高进气道的总体性能;2)可以解决低马赫数下超声速混压式进气道的起动问题;3)可以改善高马赫数下进气道的气流分离特性。为大空域、宽马赫数工作的超声速进气道的设计提供参考。

| Abstract: | A mixed-compression supersonic axisymmetric ram jet inlet coupled with mass bleed was designed and calculational results of different flight Mach numbers are obtained after the numerical simulation.Finally the analysis of inlet performance were present in the end.According to the results of this investigation,this design has such advantages as follow: 1) The general performance of the inlet has been improved;2) It could also solve the start problem of mixed-compression supersonic inlets at low Mach number;3... |
