GAP/AN推进剂的热分解催化研究

Study on Thermal Decomposition Catalytic of GAP/AN Propellant

研究了ＧＡＰ／ＡＮ推进剂的燃速与硝酸铵放热分解峰温之间的相关性，硝酸铵的放热分解峰温越低，推进剂的燃速越高。用热分析方法筛选出了ＧＡＰ／ＡＮ推进剂有效的燃速调节剂ＭＯ，它能促进硝酸铵热分解过程中质子转移反应，因而使ＧＡＰ／ＡＮ推进剂燃速提高。

A type of transitional element oxider is selected as the burning rate modifier for GAP/AN composite propellant by means of thermal analysis.The correlations both the burning rate characteristics of propellant and the decomposition temperature of AN is studied.It is shown that the lower the exothermic decomposition peak temperature of AN,the higher the burning rate of propellant.MO can increase the burning rate of GAP/AN propellant due to promoting the proton transfer reaction of AN decomposition.The burning rate modifier MO is an effective material to increase the burning rate and decrease burning rate pressure exponent of GAP/AN propellant.
