轻武器榴弹射击密集度试验方法研究

Research on Test Method of Fire Concentration of Small Arms Grenade

为研究确定轻武器榴弹射击密集度的试验方法,结合轻武器榴弹鉴定试验时的操作实际,对气象条件、弹丸初速、射角、弹道系数等影响因素进行了分析,找到了影响轻武器榴弹射击密集度散布变化的关键因素。通过运用数理统计理论建立了方差检验模型,对有关产品在不同状态下的密集度散布方差进行了检验分析。检验结果表明,弹温对密集度散布没有影响,而分组试验能够消除偶然因素带来的不利影响。为保证试验条件的一致性,建议密集度试验采用在标准温度下分3组进行的试验方法。

To research the test method of ammunition concentration of small arms grenades,the factors affecting the fire concentration,such as meteorological conditions,muzzle-velocity,fire angle and ballistic coefficient,were analyzed by combining the actual operation in the evaluation test of small-arms grenade.The critical factor affecting fire concentration was found.Based on the statistic theory,the variance checking model was established.The testing results show that the ammunition temperature has no effect on fire concentration,and the adverse effect caused by accidental reason can be eliminated by grouping test.To ensure the uniformity of test conditions,the fire-concentration test should be divided into three groups under standard temperature.
