摘要:
为获得少烟且高能量的复合固体推进剂,使用含能PBT黏合剂,制备了铝粉质量分数为5%的PBT叠氮三组元推进剂,研究了推进剂的能量、燃烧及力学性能。结果表明,推进剂在固体质量分数78%时能量和工艺性能最优,使用φ118标准发动机测试能量比冲达246.4 s;压强指数随燃速铜铬催化剂RC和增塑剂ATC用量的增加而降低;燃烧速度随RC和超细高氯酸铵AP用量的增加而升高;固化参数或键合剂用量增加后,推进剂抗拉强度升高、伸长率降低。制备的少烟叠氮配方综合性能良好,可供高性能少烟推进剂装药。
Abstract:
In order to obtain a composite solid propellant with low smoke and high energy, energetic PBT binder was used to prepare a PBT azido tri-propellant with 5% (mass fraction) aluminum. Properties, in respects of energy, combustion and mechanics, were studied. The results show that propellant presents the best energy and technological properties when the solid mass fraction is 78%, and it has a specific impulse of 246.4 s through BSF φ118 standard engine. The pressure index decreases with the increase of the dose of burning rate catalyst RC and plasticizer ATC. The burning rate increases with the increase of the amount of RC and ultrafine AP. Due to the increase of the curing parameter and the amount of bonding agent, the tensile strength increases and elongation decreases. This minimized smoke azido propellant has superior comprehensive properties and can be used in reduced smoke propellant.
