为了使冲压发动机适应更宽广的工作包线,提高工作性能,充分发挥推进剂的能量,必须设计燃气发生器流量调节装置。文中针对一种固冲发动机用流量调节装置进行了设计,完成了结构与内流场仿真计算,在仿真计算的基础上加工试验件完成了热试试验,试验结果表明设计的流量调节装置满足冲压发动机要求,可以为流量调节装置将来的实际应用作技术储备。

In order to improve the output performances, further broaden operating envelope and give full scope to the propellant perform-ance; solid-rocket ramjet motor needs flow controller. In this paper, a flow controller was designed for solid-rocket ramjet motor, its intensi-ty and inner flow field were simulated, and the test piece was machined to finish the test. The results show that the flow controller meets the requirement of solid-rocket ramjet motor, laying technological foundation for practical application of flow controller.
