电动力鱼雷动力电池管外激活发射弹道研究

Study on Trajectory of Electric Power Torpedo Launched by Battery Activated Outside Tube

为探讨电动力鱼雷动力电池采用管外激活发射时,发射参数对弹道的影响,建立了鱼雷纵平面运动模型,并针对管外激活情形对初始条件进行设定,利用Simulink编程,对横舵管制舵角、动力电池激活时间和鱼雷出管速度取不同值时的弹道进行仿真。结果表明,以上3个参数对鱼雷弹道都有影响,由小深度向大深度发射鱼雷时,横舵管制舵角应设为正值,由大深度向小深度发射鱼雷时,横舵管制舵角应设为负值,并尽量缩短动力电池激活时间,提高鱼雷出管速度,电动力鱼雷管外激活发射可获得较好的弹道。

To investigate the effect of launch parameters on trajectory of electric power tolpedo launched by battery activated outside tube, a model of torpedo movement in vertical plane is cstablished, and initial condition is set according to activation condition outside tube. Simulation of the trajectory of electric power torpedo is conducted with Simulink. The results show that the rudder angle of torpedo, the battery activation time, and the initial velocity of torpedo all affect the trajectory of torpedo. The rudder angle ought to be set positive when torpedo is launched downwards, or set negative when torpedo is launched upwards to gain perfect trajectory. Meanwhile, shorter battery activation time and higher initial velocity of torpedo are necessary.
