摘要
通过静态燃烧性能测试及 112mm发动机动态评定等实验方法 ,研究了球形铝粉及非球形铝粉对低燃速丁羟推进剂燃烧性能的影响。结果表明 ,含球形铝粉推进剂的燃速和燃速压强指数略高于含非球形铝粉的推进剂 ,而且其燃速可通过调节氧化剂的粒度级配来改变 ,而燃速温度敏感系数没有显著变化。
The effect of spherical and non spherical aluminum powder on the combustion behavior of the low burning rate HTPB propellant was studied by means of both static burning rate measurement and firing test of the 112 mm evaluation test motor. The results showed that the burning rate of the spherical aluminum propellant could be adjusted by means of variation of the particle size combination of the oxidizer. The results also showed that the burning rate at high pressure and the burning rate exponent of the spherical aluminum propellant are higher than those of the non spherical aluminum propellant. There is no remarkable change in temperature sensitive coefficient of burning rate.
