在分析了固体火箭冲压发动机的高度特性、壅塞式和非壅塞式固体火箭冲压发动机性能调节特性的基础上， 提出了燃气流量可以调节的燃气发生器， 尤其是非壅塞式固体火箭冲压发动机对贫氧推进剂的特殊要求。分析结果表明： 非壅塞式固体火箭冲压发动机要求贫氧推进剂具有高的燃速压强指数、低的可燃极限和足够好的燃烧稳定性。探讨了贫氧推进剂性能调节的途径。
Based on the analysis of the height characteristics of the solid rocket ramjet engine and the performance adjustment characteristics of the ramjet and non-ram ram ramjet engine, a gas generator with adjustable gas flow rate is proposed, especially for non-plugged solid rocket ramjet engine. Special requirements for propellants. The analysis results show that the non-plugged solid rocket ramjet engine requires the oxygen-poor propellant to have high burning rate pressure index, low flammability limit and good enough combustion stability. The ways to regulate the performance of oxygen-poor propellant were discussed.
