摘要
研究了水杨酸铅（PbSa）、水杨酸铜（CuSa）、水杨酸铋（BiSa）、甲撑水杨酸铅（Pb2Sa2）、甲撑水杨酸铜（Cu2Sa2）和甲撑水杨酸铅铜（PbCusa2）对AP-CMDB推进剂的燃烧性能和1．0MPa压强下热分解特性的影响。结果表明，水杨酸金属衍生物均能有效提高APCMDB推进剂低压下的燃速，并降低高压下的燃速。水杨酸金属衍生物均使推进剂中NC／NG体系分解峰温在一定程度上降低，CuSa和Cu2Sa2可明显降低推进剂中AP的高温分解峰温。水杨酸的含铜衍生物（CuSa、Cu2Sa2和PbCuSa2）可有效降低较宽压强范围内（1～20MPa）的压强指数。
The influence of lead （II） salicylate （PbSa）, copper （II） salicylate （CuSa）, bismuth （II） salicylate （BiSa）, lead （II） methylene-bissalicylate （Pb2Sa2）, copper （II） methylene-bissalicylate （Cu2Sa2） and lead （II） copper（II） methylene-bissalicylate （PbCuSae） on the combustion characteristics and thermal behaviors of the AP-CMDB propellants were experimentally studied. The results showed that the pressure exponents of the AP-CMDB propellants decreased in a certain extent with the increase in burning rates of the propellants at low pressures and the decrease in burning rates at high pressures. The peak temperature of thermal decompositions of binary system NC/NG in the AP-CMDB propellants were affected obviously by all the metal salicylates, and the peak temperature of thermal decompositions of AP at high temperature were brought forward obviously by CuSa and Cu2Sa2. It was also found that the pressure exponents of the AP CMDB propellants in the wide pressure range of 1～20MPa can be decreased efficiently by the copper （II） salts of salicyle （CuSa,Cu2Sa2 and PbCuSa2）.
