摘　　要：根据固体火箭冲压发动机工作原理和三维数值仿真与试验结果,建立了较为符合实际的进气道、燃气发生器和补燃室工作数学模型,并对进气道和固体火箭冲压发动机的工作包线进行了分析,提出了进一步拓宽固体火箭冲压发动机工作包线的措施,得出对燃气流量进行调节,是扩大固体火箭冲压发动机工作包线的一种可行的方法。Based on solid propellant ramjet motor operating principle and plenty of three-dimensional numerical simulation and test results, mathematical working model of air inlet, gas generator and compensation combustion chamber is built, which is relatively in keeping with reality. Air inlet and operating envelope of solid propellant ramjet motor are also analyzed. Finally, it is put forward how to further broaden operating envelope of solid propellant ramjet motor.
