霰弹子外弹道理论与计算

本文通过分析与求解霰弹子外弹道运动方程 ,给出计算圆球形霰弹子抛物运动弹道曲线、速度衰减曲线及残留能量曲线的方法。计算结果表明 ,霰弹子直径越小 ,顶点越低 ,飞的行程越短 ;水平飞行距离相同时 ,在 50 m内弹道降基本相同且不明显 ,但大于 50 m时 ,弹道降将变得愈来愈大 ,且不同弹径弹子间的弹道降差别也将变得愈来愈明显 ;水平飞行距离相同时 ,弹子愈小 ,其残留速度就愈低 ,因而其残留动能就愈小

EXTERIOR BALLISTIC THEORY AND COMPUTATION OF SHOTS

By analyzing and solving the exterior ballistic equations of shots, the paper gives a method for computing the parabolic trajectory,flying velocity curve and rudimental energy curve of shots Results of computation point to several conclusions Firstly, the smaller the diameter of the shot, the lower the top of parabolic trajectory and so the shorter the flying distance Secondly, at the same horizontal range, the drops of spots of different diameter are almost the same and can be neglected within 50m range But when the range is over 50m, the drops will become larger and so the drop difference between shots of different diameters become clearer And thirdly for the same range the smaller the size of the shot, the lower will be the rudimental flight velocity of the shot, and thus the lower the rudimental energy of the shot
