| 摘 要： | 给出了定几何混压式轴对称超声速进气道型面设计及性能计算方法,进行了算例计算。对亚临界状态下脱体激波的计算进行了研究,给出了进气道临界状态性能参数随飞行马赫数和高度的改变而变化的曲线。分析了进-发匹配过程,以及进气道的自调节能力。计算得到了基于进气道性能最优,即进气道工作在临界状态条件下,碳氢燃料冲压发动机的供油规律,为进气道大范围寻优设计打下了基础。

| Abstract: | Geometric design method of mixed-compression fixed-geometry axisymmetric supersonic ramjet inlet was presented.Performance calculations of inlet under on-or off-design conditions were carried out with special attention to the detached bow shock calculation during subcritical operations.The influence of flight Mach number and altitude on inlet critical condition performance has been evaluated.The inlet-engine matching mechanism was investigated, and the fuel supply characteristics were obtained to maintain the optimum inlet performance.The successful study provides a good reference to the design of ramjet supersonic inlets. |

| Keywords: | aerospace propulsion system supersonic inlet performance calculation detached bow shock inlet-engine matching fuel supply characteristics |
