弹丸杀伤半径计算方法研究

Calculation Method of Killing Radius

目前靶场主要采用扇形靶试验方法来测定弹丸的杀伤半径,其原理就是弹丸垂直放置,按不同距离分别设置6个圆心角为60°的靶,通过破片命中靶板的统计结果,来计算弹丸的杀伤半径。扇形靶试验结果原理上等同于弹丸综合威力试验时轴向90°的状态,其定义可以用杀伤概率来表示,即一定距离处一个人形靶上命中一块破片的概率为0.632时,该距离为杀伤半径。杀伤半径的结果可以通过分析弹丸综合威力试验数据进行计算,而不必要再次开展扇形靶试验。

Sectorial target test method is mainly used to measure killing radius, the principle is that the projectile is placed vertically, 6 tar- gets with the central angle of 60°are placed according to different distance, the projectile＇s killing radius can be calculated through statisti- cal result of fragments hitting target. Sector target test result is theoretically equivalent to axially 90° state in projectile synthetic power test, the distance is the killing radius when the kill probability is 0. 632. Lethal radius results can be obtained by analyzing the projectile syn- thetic power test data with no need to conduct sector target tes： again.
