超高燃速推进剂的压力敏感性

A Study on Ultra High Burning Rate Propellants with Low Pressure Indices

摘要: 分析了超高燃速推进剂的压力敏感性，提出了一种降低超高燃速推进剂压力敏感性的物理方法，即通过估算，以不同密度和不同孔结构参数的多段药片组合成ＵＨＢＲ药柱。实验证明理论估算与实测ｐ－ｕ关系，在规律上非常一致，证实用这种方法可以降低ＵＨＢＲ燃烧过程的表观压力指数。

Abstract: Pressure sensitivity of the burning rates of ultra high burning rate (UHBR) propellants is analyzed. Possibility of reducing the pressure sensitivity of UHBR propellants is studied by a physical method. Experimental results show that pressure sensitivity of UHBR propellants may be reduced in this way.
