| 摘要: |
| 建立了一种新型非壅塞燃气发生器固体火箭冲压发动机系统。一系列直连式实验证实，验证的镁铝中能贫氧推进剂在低压（≥０．５ＭＰａ）范围内可以稳定燃烧，燃气发生器的工作压强可以随冲压补燃室压强的改变而变化，因此贫氧推进剂燃速随之进行自适应调节，最终达到富燃烧气流量自主调节的目的。 |

| Abstract: |
| A new type of unchoked solid rocket ramjet system was established.The test results show that a magnesium aluminum fuel rich propellant can burn steady at the pressure as low as 0 5MPa,and the pressure of gas generator can be adjusted according to the variation of ram combustor pressure.Therefore,the burning rate of fuel rich propellant can adjust adaptively with the variation of ram combustor pressure. |
