反坦克火箭筒横倾状态下射击偏差的定量分析

反坦克火箭筒发生横向倾斜时会影响火箭弹的射击精度,导致射击出现偏差。通过建立反坦克火箭筒的坐标系,描述反坦克火箭筒横倾前后的筒身状态,通过分析和坐标变换,得出横倾状态下射击偏差量的数学模型。利用Origin软件,计算了使用典型弹种射击时,反坦克火箭筒在不同距离、不同横倾角度下的方向和高低偏差量。通过对计算结果的分析表明,横倾造成的方向和高低偏差量,随着射击距离和横倾角的增大而增大,但是对于火箭弹的射击精度影响程度不同,高低偏差量极小,可以忽略不计,方向偏差量较大,需要进行修正。该计算方法和结论可为制定精确射表提供参考。

The Quantitative Analysis of Deviation About Rear Sight for Anti-tank Rocket on the Slope

The shooting accuracy of the anti-tank rocket would be influenced and the shooting deviation caused if the anti-tank rocket leaned to one side. Through building up the anti-tank rocket coordinate system, describing the state of body of anti-tank rocket before or after the time when it heeled, analyzing and changing the coordinate system, mathematics model of shooting deviation could be calculated under the heeling condition. By using Origin software, the deviation in terms of direction and height was calculated on different degrees and different distances when typical bombs are used for anti-tank rocket. Through analyzing the calculating result, the deviation in terms of direction and height for heeling would become larger with the increase of the degree of slope and the distance of shooting, but the difference in affecting shooting accuracy, the deviation of height could be ignored if it were extremely small, but the deviation of direction would be corrected if it were larger. The calculating method and result can offer reference for formulating firing table accurately.
