空投鱼雷水中弹道的准确预报对于目标物的打击至关重要。由于海洋环境的复杂性，导致鱼雷的水中弹道受到多种因素制约。为分析海流速度以及鱼雷攻角对鱼雷水中弹道的影响，本文基于鱼雷六自由度运动方程，在鱼雷运动方程中引入随机海流的影响，模拟分析不同海流速度、不同攻角下的鱼雷水中弹道以及鱼雷弹道散布，给出相应的仿真结果，探讨鱼雷弹道的散布规律。
The accurate prediction of underwater trajectory of airdropped torpedo is vital to attack specific targets. Lots of factors can influence the underwater trajectory of airdropped torpedo due to the complex marine environment. In order to analyze the influence of current velocity and torpedo attitude to the torpedo trajectory, based on six-degree motion equation, this thesis adds the influence of random current to the motion equation to stimulate the underwater trajectory of torpedo as well as the torpedo's trajectory distribution under different current velocity and attitude. And finally the corresponding simulation results are posed and the distribution regularity of torpedo trajectory is discussed as well.
