| 摘 要： | 提出了一种带有中间喷管的新型双脉冲固体火箭发动机技术方案，设计了一台结构参数可调的试验发动机；改变发动机的结构参数进行多次点火试验，获得了试验数据；对该发动机的多喉道流动过程建立了二维非稳态流动模型，对试验方案进行了大量计算，并与试验数据进行了比较分析。试验结果与理论计算基本吻合，结构可靠，对工程设计有参考价值

| Abstract: | A new type of dual-pulse solid rocket motor concept with an intermediate nozzle is presented and a test motor with changeable structural parameters was designed.Several firings of the motor with changing the structural parameters were conducted and the corresponding experimental data were obtained.A two-dimensional unsteady mathematical model was constructed for analyzing the multithroat flowfields,and numerical calculation with this model was completed.The results were compared with the test data. |
