Initial Trajectory of Wire-guided Torpedo Launched by Battery-Activated Outside

为研究线导鱼雷动力电池管外激活发射初始弹道,文中运用流体力学理论,对线导鱼雷出管过程动力学进行分析。基于鱼雷航行动力学方程,结合线导鱼雷特点,建立线导鱼雷管外激活出管纵向运动模型,分别对横舵管制舵角和鱼雷出管速度取不同值时,纵平面初始弹道进行仿真,得到动力电池激活前鱼雷与发射艇的水平距离、深度差、鱼雷俯仰角以及速度的变化曲线,并对仿真数据进行分析。结果表明:以上2个参数对线导鱼雷管外激活初始弹道以及鱼雷航行姿态都有影响,通过合理设定横舵管制舵角,并尽量提高鱼雷出管速度,线导鱼雷管外激活发射可获得安全的初始弹道以及良好的姿态控制,验证了该发射方式的可行性。

To study the initial trajectory of a wire-guided torpedo launched by a battery-activated outside tube,hydrodynamictheory was used to analyze the dynamics of the torpedo when sailing outside the tube.Subsequently,a dynamic model of thetorpedo movement in the vertical plane was built based on the dynamic equations of the torpedo and characteristics of a wire-guided torpedo.The initial trajectory of the longitudinal plane of the torpedo at different values of rail control rudder angle andtube speed was simulated.The horizontal distance and depth difference between the torpedo and launch boat,torpedo pitchangle,and speed were all obtained before power battery activation;thereafter,the simulation data were analyzed.The resultsshow that the above two parameters influence the initial trajectory and navigation attitude of the wire-guided torpedo.A safeinitial trajectory and good attitude control were achieved by setting the rail control rudder angle,improving the tube speed,andverifying the feasibility of the launch method.
