研究了10种不同纳米催化剂对双基或RDX-CMDB推进剂燃烧性能的影响,发现经表面处理的纳米复合物(n-TPCC)是一种非常有效的纳米催化剂,它使得双基推进剂在6～10MPa呈现麦撒燃烧特征,8～10MPa的压力指数为-0.867;改进n-TPCC加入方法后,可显著提高n-TPCC在低压下的催化效率;在RDX-CMDB推进剂中,n-TPCC与碳黑复合后,其催化效率进一步提高,且使推进剂在12～22MPa出现了一个宽压力范围的平台区,燃速压力指数小于0.3。 The effects of 10 different nanocatalysts on the combustion performance of binary or RDX-CMDB propellants were investigated. The surface-treated nanocomposite (n-TPCC) was found to be a very effective nanocatalyst, 6 ~ 10MPa, the pressure exponent of 8 ~ 10MPa is -0.867; The catalytic efficiency of n-TPCC at low pressure can be significantly improved by the improved n-TPCC addition method; in RDX-CMDB propellant, After the composite of TPCC and carbon black, the catalytic efficiency of TPCC is further increased, and a wide pressure range of platform area appears at 12 ~ 22MPa, the burning pressure pressure index is less than 0.3.
