RDX-CMDB推进剂中组合催化剂的研究

AN INVESTIGATION ON THE EFFECT OF COMPOSITE CATALYSTS USED IN RDX-CMDB PROPELLANT

利用正交设计结合方差分析的方法对RDX-CMDB推进剂中邻苯二甲酸铅(φ-Pb)和炭黑(CB)催化剂进行了较全面的研究,得到了φ-Pb和CB对推进剂燃烧性能的影响规律及其作用区域,并从影响显著性的角度,解释了催化剂之间的协同作用及其使推进剂产生平台燃烧的原因。

By using the orthogonal design and variance analysis, lead phthalate (φ-Pb)and carbon black(CB) added in RDX-CMDB propellants as combustion catalysts have been investigation in this parper. The effect of φ-Pb and CB on combustion properties of the propellants, and their action region are obtained. In terms of the significance of effect, the synergism of φ-Pb and CB and the plateau combustion phenomenon of the propellants are explained.
