本文报导了长纯金属丝对双基及挤压改性双基推进剂燃烧性能的影响.指出双基推进剂中嵌入长纯金属丝后可以大幅度提高燃速,同时对压力指数和温度系数也有相当大的影响.这些与金属丝的材料、尺寸和推进剂的类型、性能有关.弄清这些关系和规律,以利于发动机装药设计者对这类推进剂的选择和使用 This paper reports the effect of long pure metal wire on the combustion performance of double base and extrusion modified double base propellants.It is pointed out that the burning rate can be greatly increased after the embedded pure wire is inserted into the double base propellant and the pressure index and temperature coefficient Also have a considerable impact on the wire material, size and type of propellant, performance related to clarify these relationships and laws in order to facilitate the design of the engine chargers of such propellant selection and use
