Analysis of Torpedo Positions Externally Hanged on UUV Based on CFD

摘要: 为确定无人水下航行器（UUV）外挂鱼雷的最佳位置, 该文首先利用UUV外挂鱼雷后的水下稳性计算,初步确定鱼雷的外挂位置, 然后采用FLUENT软件计算了鱼雷不同外挂位置对整体流体动力参数的影响, 根据选定的UUV最终确定其外挂鱼雷的最佳位置为UUV底端两侧, 并利用SIMULINK建立空间运动性能仿真模型, 对外挂位置进行了动态运动性能的仿真计算, 进一步验证了最佳外挂位置的计算结果。Abstract: In order to analyze the optimum positions of external torpedoes hanged on unmanned underwater vehicle (UUV), we first determined the external positions preliminarily via the underwater stability of the UUV after hanging torpedoes, and then calculated the hydrodynamic parameters of different external positions by FLUENT. According to the selected UUV, the best positions of the external torpedoes were obtained on both sides of the bottom of UUV. The dynamic motion characteristics of external positions are simulated by establishing SIMULINK spatial motion model, and the calculated results of the best positions are verified.
