迭代法求解某型鱼雷射击诸元研究

Research on Solving a Certain Torpedo Firing Data Using Interaction Method

分析了美国MK46-5型鱼雷的发射弹道,建立了迭代法求解模型,将鱼雷入水后的弹道进行了详细分析,并且综合考虑了该鱼雷发射后的各种误差,采用迭代的方法求解其转角,进而求解出一次搜索主航向、自导开机距离及直航搜索距离等射击诸元,采用迭代的方法进行求解,射击参数的解算不仅提高了精确度,而且易于系统工程上实现。研究成果对进一步研究其作战作用问题打下了基础,对提高水面舰艇反潜防御能力和生存概率具有重大的现实意义。

By analyzing the trajectory of the MK46-5 type of torpedo of the America, considering main errors after firing, using the interaction method, this article gets the firing data such as changing angle, first-search course, the distance when the homing guidance takes effect, the distance of straight-running searching, and etc. This paper lays a foundation for further research on the operational application of the torpedo, and thus gives very significance for vessel on improving defense effectiveness and survival probability against submarine.
