Process Simulation of Torpedo Swim-out Launching from UUV

摘要: 无人水下航行器(UUV)外挂鱼雷具有重要的战术价值。由于UUV体积小、质量轻, 自航发射鱼雷时运动状态会发生改变。为了定量分析这种变化以验证发射的可靠性, 建立了UUV自航发射鱼雷的运动模型, 根据此模型利用FLUENT对发射过程进行了仿真。仿真结果表明, UUV发射鱼雷时运动状态会发生一定的变化, 但采用自航发射仍然具有可行性。同时得出鱼雷脱离发射导轨时的运动参数, 为精确计算鱼雷的外弹道提供了依据。Abstract: Externally hung torpedo on an underwater unmanned vehicle(UUV) is of great tactical significance in warfare. Because UUV is small in volume and light in weight, its movement state will change when a torpedo swims out from it. In this paper, to analyze quantitatively the parameter change for verifying the reliability of torpedo launching, a movement model of a torpedo swim-out launching from UUV is built, and the launching process is simulated by the software FLUENT. Simulation results indicate that the movement state of UUV changes in the launching process, but this change will not significantly affect torpedo swim-out launching. In addition, the movement parameters of the tor-pedo leaving the launcher are obtained, which may provide a reference for precise calculation of torpedo’s exterior tra-jectory.
