为提高固体冲压发动机贫氧推进剂在低压领域的自燃性、燃速和比冲，对会高燃烧热金属粉的固体推进剂进行研究。证明添加高燃烧热金属钛可以提高低压领域的自燃性和燃速。以提高燃速为目的探讨了埋入银丝推进剂的燃速特性，在贫氧推进剂中也取得了与具有适当比例氧化剂的推进剂同样的银丝效应。 In order to improve the spontaneous combustion, burning rate and specific impulse of low-oxygen propellants in solid ramjet engines, the solid propellants that burn hot metal powders will be studied. Prove that adding high combustion hot metal titanium can improve the self-ignition and burning rate in the low pressure area. In order to improve the burning rate for the purpose of discussing the burnt silver propellant burning rate characteristics, in the oxygen-poor propellant also achieved with the appropriate proportion of oxidant propellants with the same silver wire effect.
