摘要:
为定量表征发射药的破碎程度,引入了燃气生成速率比的概念。通过理论推导,得出燃气生成速率比即为破碎发射装药与相应未破碎发射装药的燃烧表面积比。提出采用破碎发射药燃烧前期的燃气生成速率比的平均值来定量表征发射药的破碎程度。对标准发射药、大块发射药、小块发射药和粉末发射药进行了密闭爆发器试验,获得了不同发射药的p-t曲线,数据处理得到不同发射药破碎程度的量化值。结果表明,基于燃气生成速率比的发射药破碎程度定量表征方法是可行的。
Abstract:
To characterize fragmentation degree of propellant quantitatively, ratio of gas generation rates was introduced. It was deduced that the ratio of gas generation rates is correlated to the ratio of burning surface area of crushed propellant to that of the standard propellant. Fragmentation degree of propellant is characterized with the average value of the ratio of gas generation rates at the initial time. Closed-bomb test was used to test the standard propellant, massive propellant, bite-size propellant and powdered propellant, and the curves of the different propellants were obtained. The quantitative value of the fragmentation degree of propellant was obtained by processing the p-t curves. Results show that the quantitative characterization method for fragmentation degree of propellant based on the ratio of gas generation rates is feasible.
