横滚对鱼雷直航弹道的影响及对策

Influence of torpedo roll on rectilinear motion trajectory and countermeasure

鱼雷直航弹道是其水下航行弹道的重要组成部分,横滚又是鱼雷航行弹道的一个普遍现象,而横滚对直航弹道的最大影响是航向偏差,这个问题一直是直航弹道研究的重点。文中指出鱼雷上爬(下潜)和地球自转引起的转子轴与鱼雷纵轴的夹角是横滚产生鱼雷航向偏差的根源,并对此展开了定性分析和实例解算,得出相应结论。结合装备及使用情况,提出并详细论证了相应的补偿方法。综合分析表明,通过鱼雷技术准备时提前进行补偿或在组织射击时进行提前角(转角)修正,可以较好地解决因横滚而产生的鱼雷航向偏差问题。

Torpedo rectilinear motion trajectory is an important constitute part of underwater trajectory,and torpedo roll is a common phenomenon of underwater trajectory,the biggest influence of torpedo roll on rectilinear motion trajectory is course deviation,it has been the research emphasis of rectilinear motion trajectory all along.This paper points out that the angle between gyroscope axis and torpedo axis is the origin of course deviation due to torpedo roll,moreover the angle is caused by torpedo depth change and rotation of the earth.The course deviation by torpedo roll was analyzed qualitatively,and some conclusion was obtained by solving examples.The relevant compensation methods were put forward and discussed exhaustively base on the actual situation of torpedo.The results show that proper compensation during torpedo technical preparing and adjusting lead angles before shoot torpedo are good ways to solve the course deviation by torpedo roll.
