一种平衡抛射单兵反装甲武器发射装药低温发射安全性分析

Analysis of Launch Safety of an Equilibrium Launching Individual Anti-armor Weapon at Low Temperature

发射膛炸的概率是评估武器使用安全性的重要性能指标。旨在研究某平衡抛射的单兵反装甲武器发射装药的发射安全性评估方法。分析了该武器系统的低温内弹道性能,建立了一种预测膛炸事故概率的方法,通过统计推断其低温最大膛压服从三参数Weibull分布,计算了其发射装药引起膛炸事故的概率。结果表明该武器发生膛炸概率较大,并通过改进消除了膛炸隐患。建立的膛炸概率预测方法可用于平衡抛射单兵反装甲武器、迫击炮、无坐力炮等武器的发射安全性分析。

The probability of bore burst is an important performance criterion for evaluating the launch safety of weapons.A method for evaluating the launch safety of propellant charge of equilibrium launching individual anti-armor weapon was studied.The interior ballistic performance of this weapon system was analyzed at low temperature,a method was presented for forecasting the probability of bore burst accident,and the probability of bore burst accident caused by propellant charge was calculated by statistically inferring its maximal barrel pressure at low temperature to obey 3-parameter Weibull distribution.The result shows that the probability of bore burst is very big,and this problem can be overcome by improvement.The forecasting method can be used to analyze the launch safety of weapons,such as equilibrium launching individual anti-armor weapon,mortar and recoilless gun.
