    摘要:

    奥克托今(HMX)作为含能材料在能够提高推进剂能量性能的同时可改变推进剂的燃烧过程,广泛用于固体推进剂中。为了研究HMX含量对推进剂点火、燃烧、团聚和凝聚相燃烧产物特性的影响,采用推进剂燃面拍摄、激光点火以及凝聚相燃烧产物收集方法对HMX含量在0%~10%范围内的典型四组元推进剂进行试验研究。结果表明:随着HMX含量由0%增加到10%,推进剂的点火延迟时间由191 ms增加到286 ms,推进剂的燃速和压强指数均减小,凝聚相燃烧产物的体积平均粒径D43由48.1 μm增加到138.3 μm。含10%HMX的推进剂燃面上铝的团聚程度最大,而含8%HMX的推进剂凝聚相燃烧产物中活性铝的含量最高。

    Abstract:

    As an energetic material, octogen(HMX) is widely used in solid propellants. While improving the energy performance of the propellant, it also changes the combustion process of the propellant. To study the effect of HMX content on the ignition, combustion, and agglomeration properties of propellant and its condensed phase combustion products (CCPs), burning surface photography, laser ignition and collection of the CCPs were used for testing and studying typical AP/HTPB/Al/HMX propellants with HMX contents ranging 0%-10%. Results show that as the HMX content increases from 0 to 10%, the ignition delay time increases from 191 ms to 286 ms, and both the burning rate and pressure exponent of the propellent decreases. The volume average particle size of the CCPs increased from 48.1 μm to 138.3 μm. The propellent with 10% HMX has the highest agglomeration degree on the burning surface, while the propellent with 8% HMX has the highest active aluminum content in the CCPs.
