本文详细地阐明了“诱导滚转力矩”和“诱导侧向力矩”的产生机理,并应用了“诱导滚转力矩”、“诱导侧向力矩”、“转速闭锁”等概念,从理论上讨论了迫击炮弹出现近弹的三种情况,分析了产生近弹的原因。同时给出了迫击炮弹外形不对称的上限,对如何避免近弹,提出了初步的看法。 本文可供迫击炮弹设计工作者及外弹道研究人员参考。
In this paper, the mechanism of “inducing rolling moment” and “inducing lateral moment” are explained in detail, and the concepts of “inducing rolling moment”, “inducing lateral moment” and “rotation speed locking” are applied and discussed theoretically The mortar rounds appeared in three cases of nearly bouncing, analyzed the reason for the near-bounce. At the same time, the upper limit of asymmetric mortar shell shape is given, and a preliminary view is given on how to avoid near-miss. This article is for reference by mortar shell designers and outside ballistic researchers.
