鱼雷依靠惯性以一定姿态跃出水面并再次落入水中的过程称之为鱼雷的豚跳运动. 针对鱼雷的豚跳运动需要以零攻角入水, 而鱼雷在空中运动过程中无法控制的问题, 提出了通过构建鱼雷豚跳运动模型并以此为基础控制初始出水转动角速度的解决方法. 附加质量、浮力、浮心、浸湿面积、浸水体积等变量随鱼雷出水姿态、出水过程不同而不同. 在构建鱼雷豚跳运动模型过程中, 充分考虑了各个变化物理量的导数项, 分析了鱼雷水动阻力系数与攻角的关系, 构建了运动模型, 得出鱼雷豚跳运动的规律. 利用优化搜索算法计算出使鱼雷豚跳以零攻角条件入水的初始转动角速度. 仿真结果表明了所建模型及控制初始转动角速度方法的有效性.The process which the torpedo, with relying on its inertia, jumps out of water in a certain gesture and falls into water, is called dolphin-leap. According to the dolphin-leap, the torpedo is required to get into the water at its zero angle of attack, but this gesture cannot be controlled during the torpedo moving in air. In order to solve the problem, a solution to control the initial water-exit rotational angular velocity is developed according to the proposed dolphin-leap model. The variables like added mass, buoyancy, buoyant center, wetted area, wetted volume, etc. are dependent on water-exit gesture and process. The derivative term of each physical quantity is fully considered in the dolphin-leap model, and the relationship between torpedo's hydrodynamic drag coefficient and attack angle is analyzed, then the motion model is built and the torpedo's dolphin-leap law is obtained. The optimal search algorithm is used to obtain the initial rotational angular velocity which makes the torpedo dolphin-leap fall into the water at its zero angle of attack. Simulation results show the validity of the proposed model and the solution for controlling the initial rotational angular velocity.
