炸高对爆炸超压的影响规律

Influence Rule of Bursting Height on Blast over Pressure

对炸高影响爆炸超压的规律进行了理论分析和实验研究。提出了描述超压与对比炸高和对比距离两个变量的拟合公式。得到了最有利的起爆高度(对比炸高)与对比距离的关系。得出最佳炸高条件下冲击波超压随对比距离的衰减曲线,可近似为一条直线,该曲线上的冲击波超压高于其他条件的超压值。

The influence rule of bursting height on blast pressure was studied theoretically and experimentally. Based on the theory analysis, a formula descriheing the variation of overpressure with specific bursting height and scaled distance to explosion center was proposed. The optimal specific bursting height varying with scaled distance was obtained. Variation of the peak overpressure with scaled distance to explosion center was deduced under the condition of optimal specific bursting height consequently,and it can be approximated as a straight line,under which the pressure is not less than other conditions. It can be used to guide the warhead performance design of FAE.
