惰性与含能催化剂对Al-RDX-CMDB推进剂燃烧性能的影响

研究了含能铅盐Ｂ、芳香酸铅盐Ｃ、芳香酸铜盐Ｂ、炭黑ＣＢ１或ＣＢ４作为催化剂（单独使用或两者复合或三者复合使用）对螺压Ａｌ－ＲＤＸ－ＣＭＤＢ推进剂燃速和压力指数的影响规律。指出了无论是含能铅盐Ｂ还是芳香酸铅盐Ｃ，当它们分别与铜盐和炭黑组成铅－铜－炭复合催化剂时，都有良好的提高燃速和降低压力指数的“协同效应”。含能铅盐Ｂ燃烧催化剂活性比芳香酸铅盐Ｃ要高，故使用量少，对提高配方能量有益。含能铅盐Ｂ燃烧催

EFFECT OF NONENERGETIC AND ENERGETIC CATALYSTS ON THE COMBUSTION BEHAVIOR OF Al-RDX-CMDB PROPELLANTS

The effect of several combustion catalysts,such as energetic lead salt B,aromatic acid lead salt C,aromatic acid copper salt B,carbon black CB₁ or CB₄,on the combustion behavior of screw-compressed Al-RDX-CMDB propellants was investigated when they were used alone or as a combination of two or three of them. The experimental results show that both energetic lead salt B and nonenergetic aromatic acid lead salt C are able to increase the burning rate and decrease pressure exponent of the propellants when they are respectively used together with copper salt and carbon black.The catalytic activity of energetic lead B is higher than that of aromatic acid lead salt C.The reason is that the thermal decomposition product PbO of energetic lead salt B has a higher catalytic activity than the later's.
