摘要:

本文系统地研究了TMO(过渡金属氧化物)对AP热分解性能和AP/AI/HTPB推进剂燃速的催化作用.结果发现,TMO对AP热分解反应和AP/AI/HTPB推进剂燃速的催化作用是一致的.文中指出了与AP热分解反应和AP/AI/HTPB推进剂燃速同时有关的表征参数,为采用热分析实验预估含铝推进剂的燃速奠定了基础.

Abstract:

The effect of TMOs (Transition Metal Oxides) on the thermal decomposition characteristics of AP and on the burning rates of AP/A1/HTPB propellants was studied in this paper. The results show that the catalysis of TMOS on the thermal decomposition of AP is consistent with that on the burning rates of aluminized propellants. It was found that the characteristic parameters of thermal decomposition is also related to the burning rates of the propellants,which make it possible to predict burning rates of aluminized propellants by the data of AP/TMO thermal decomposition.
