尾流自导鱼雷最小开机距离及其应用

Research on Minimum Homing Triggering Distance for Torpedo Wake Homing Device and its Application

基于尾流自导鱼雷的制导原理、弹道和自导开机过程,提出了最小开机距离的概念。分析指出了影响尾流自导鱼雷最小开机距离的主要因素是设定的鱼雷深度、鱼雷的航行精度和目标运动参数散布等。建立了最小开机距离的计算模型,并在不同攻击态势下进行了仿真计算和统计分析,得出了有益的结论:在一定的攻击条件下,不同的设定深度、使用不同的鱼雷速制以及不同的目标运动要素误差、鱼雷航行精度,将使鱼雷的最小开机距离不同,即鱼雷的最小开机距离实际上是关于各种因素的函数。通过最小开机距离可以进一步计算出鱼雷自导开机的最大距离,若在工程中予以实现,将对提高潜艇攻击的隐蔽性和鱼雷作战效能具有重要意义。

Based on wake homing guidance principle,ballistic and the switching on process of wake homing device,a concept of switching on minimum distance has been proposed.The main factors that influence the distance are analyzed.Those factors include torpedo navigation depth,torpedo navigation accuracy,and target position error.Mathematical model of minimum distance is established.Simulation is conducted under different attacking conditions and results are analyzed statistically.Some useful conclusions are drawn： Minimum distance varies with torpedo depth and speed.It also varies with the target motion parameter error and torpedo navigation error.Maximum distance can be calculated from the distance.Application of the concept in torpedo projects will improve the submarine concealment and torpedo combat efficiency.
