摘要
为了减小纵向倾斜状态下的狙击步枪射击偏差,文中提出了一种狙击步枪射击偏差校准方法,通过对狙击步枪纵向倾斜角度进行改变,分析了狙击步枪在纵向倾斜状态下射击偏差量变化规律,建立了狙击枪子弹运动轨迹的数学模型,研究了存在空气阻力和理想状态下的运动轨迹曲线。研究结果表明:纵向倾斜造成的方向偏差量随着射击距离及纵倾角度的增大而增大,通过对风偏系数和气压进行修正,得出在不同射击距离下需要修正的具体格数,为狙击步枪的射击精度提供了更有效的参考数据。
In order to reduce the shooting deviation of a sniper rifle in the longitudinal tilt state,the paper presents a method for calibrating the shooting deviation.By studying the change of the longitudinal inclined angle of the sniper rifle,the variation law of the shooting deviation of the sniper rifle in the longitudinal inclined state is obtained,and the mathematical model of the bullet trajectory of the sniper rifle is established.The trajectory curves in the presence of air resistance and ideal conditions are studied.The results show that the direction deviation caused by the longitudinal tilt increases with the increase of the shooting distance and the longitudinal tilt angle,and the wind deflection coefficient and the air pressure are corrected.The specific lattice number that needs to be corrected for different shooting distances is summarized,which provides more effective reference data for the shooting accuracy of sniper rifles.
