| 摘 要： | 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呈现麦撤燃烧特征，8～IOMPa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。

| Abstract: | The effects of ten kinds of nano-catalysts on the combustion properties of DB/RDX-CMDB propellant were investigated. The results show that the treated nano-composite (n-TPCC) is an effective combustion catalyst. The catalyst enables the double base propellant to emerge the mesa effect between 6 and 10MPa and its pressure exponent to decrease to -0.867. Improving the addition method of n-TPCC can obviously increase the catalytic effectivity at low pressure. The n-TPCC added together with carbon black brings about RDX-CMDB propellant to possess the higher burning rates, to produce wider plateau zone from 12MPa to 22MPa and to decrease the pressure exponent to less than 0.3. |
