摘　　要：采用微测温和火焰照相及SEM研究了含硼富燃料推进剂燃烧波温度分布、火焰结构及熄火表面;结合热力计算,分析含硼富燃料推进剂中硼燃烧反应类型。研究认为低压下推进剂燃烧波结构存在暗区;硼表面用AP包覆,可以降低暗区厚度,有利于改善推进剂的燃烧。The combustion wave temperature profiles, the flame structure and extinguished surface of boron-based fuel-rich propel-lant are investigated by means of temperature measuring, flame photograph and SEM. The reaction styles of the propellant are analyzed based on the thermodynamic calculation. Dark zone is discovered in combustion wave structure of the propellant at low pressure. It will decrease the dark zone thickness and improve combustion performance by use of coeted boron with AP.
