摘要

摘要: 随着火箭助飞鱼雷入水速度越来越高, 鱼雷入水安全性对入水姿态变化越来越敏感, 而在雷伞系统降落过程中, 极易出现圆锥摆运动, 导致鱼雷入水时攻角过大, 巨大的击水载荷会使鱼雷结构发生破坏。为提高鱼雷入水安全性, 需采取一定的稳定控制措施, 有效减小鱼雷入水前攻角。文章结合雷伞系统多体运动仿真模型和基于脉冲姿控发动机的姿态控制策略开展雷伞系统姿态控制技术研究, 对鱼雷入水前的雷伞弹道和带伞姿控过程进行了仿真, 仿真结果表明, 当降落伞锥摆频率与鱼雷摆动频率接近时鱼雷才会出现明显的锥摆运动, 而通过引入姿控过程破坏鱼雷自身锥摆频率可以显著减小降落伞锥摆对鱼雷的影响, 使得在一定条件下带伞姿控可以取得很好的姿态控制效果。

Abstract: The safety of a rocket-assisted torpedo entering water becomes more sensitive to the water-entry angle as the water-entry speed of the torpedo increases. Conical pendulum motion is likely to occur during the descent of the torpedo-parachute system. The pendulum movement causes the torpedo to have an excessively large angle of attack when it enters the water, resulting in a large impact load that damages the torpedo. To prevent structural damage to the torpedo as it enters the water, it is necessary to reduce the angle of attack before the torpedo enters the water. In this study, the multi-body motion simulation model of the torpedo system and the attitude-control strategy based on pulse attitude control engine are combined to analyze the attitude-control technology of the torpedo system. Simulation results indicated that when the frequency of the conical pendulum motion of the parachute was close to that of the torpedo, the torpedo had obvious conical pendulum motion, and the influence of the parachute on the torpedo could be significantly reduced by introducing the attitude-control process to change the conical pendulum frequency of the torpedo. Thus, under certain conditions, attitude control of the torpedo with the parachute can achieve feasible results.
