摘要
快燃物ACP作为一种有效含能助剂用来提高推进剂的燃速具有一定的效果。通过DSC和TG-DTG研究了ACP对无烟改性双基推进剂(CMDB)热分解特性的影响,采用靶线法研究了不同含量的ACP对无烟改性双基推进剂燃速和燃速压力指数的影响,用燃烧火焰单幅照相技术和微热电偶测温获得了含ACP无烟改性双基推进剂在稳态燃烧条件下的火焰结构和燃烧波温度分布,分析了该推进剂中主要组分对燃烧性能的影响。结果表明:含ACP推进剂的燃速随ACP含量的增加而增大,推进剂燃烧火焰结构随ACP含量增加而更加明亮。
Fast-burning energetic compound （ACP） is one of the most important additives to increase the burning rate of solid propellant, the decomposition effects of ACP to the composite modified double-based （CMDB） propel- lant were investigated by means of differential scanning calorimeters （DSC） and thermogravimetry-derivative ther- mogravimetry （TG-DTG） experiments, the burning rate of CMDB propellant with ACP was determined. The ＇flame structure and the combustion wave temperature distribution of CMDB propellant with ACP samples were measured by means of flame photo technique and micro-thermal-couple, respectively. The effect of the major components of propellant on the combustion properties was analyzed. The results show that the burning rate of CMDB propellant with ACP increases with increase in the mass content of ACP, the brightness of combustion structures is luminous with increase in the content of ACP.
