含催化剂的RDX-CMDB推进剂熄火表面形貌特征和燃烧火焰结构分析

Quenched Surface Characteristics and Flame Structure of RDX-CMDB Propellants Containing Catalyst

对分别含有Pb盐、Pb/C双元催化剂及Pb/Cu/C三元催化剂的三种RDX CMDB推进剂熄火表面形貌特征和燃烧火焰结构进行了研究。结果发现 ,不同的催化剂可导致推进剂熄火表面的特征物类型和几何尺寸不同 ,燃烧表面上明亮物质的几何形状、亮度不同。压力增大 ,推进剂燃烧火焰变得更加明亮。

The quenched surface characteristics and flame structure of RDX CMDB propellants containing single lead salt,or Pb/C binary catalysis system,or Pb/Cu/C tribasic catalysis system were investigated. It is found that different catalyst systems bring about different types and sizes of characteristic substances borned on the quenched surface of the propellants, and different geometrical shapes and brightness of the luminous substances on the combustion surface.The flame of the propellant becomes much brighter with the pressure increase.
