摘要
采用了多种实验测试手段，对不同类型的合利贫氛推进剂燃烧特性进行了研究，由括它的热分解、点火性能、能量特性、燃烧现象及流场温度分布等特征．结果表明，配方中加入经过包覆处理的硼粉是有利的，但要有合理的比例；添加LiF或镁粉需要综合考虑其利弊；选取适宜的硼粒子包覆方案是提高硼燃烧效率的重要途径。
By several experimental measurement methods, the combustion characteristics of various boronbased fuel-rich propellants, such as thermal decomposition, ignition temperature, energy behaviour, combustion phenomena and temperature distribution in flow field are investigated. The experimental results points out that it is beneficial to add coated boron into the formula with reasonable ratio. Furthemore the benefit by adding LiF or Mg should be comprehensively considered. It is necessary to select suitable scheme to coat boron for raising the combustion efficiency.
