摘要
本文建立了弹丸在后效期内运动的动力学模型,模型包括:弹丸自转、质量偏心、动不平衡、气体压力等.求得了弹丸在后效期内运动的解析公式.并对某23mm弹炮系统进行了计算,得到了一些初步结论.
A dynamic model of a projectile travelling in the aftereffect period of proopellant gas is developed in this paper.The model ac-commodates projectile spin, mass eccentricity, dynamic unbalance, gas pres-sure. etc.The analytical formulation of the projectile motion in the aftereffectperiod of propellant gas is made. A computation is made for a 23mmprojectile-gun system and some basic conclusions are reached.
