摘　　要：超空泡航行体全沾湿航行阶段尾舵展开过程的流体动力载荷对于航行体稳定性分析以及尾舵机性能设计具有重要影响。建立了基于重叠网格技术和网格域间相对运动思想的尾舵展开过程数值计算方法;结合超空泡航行体设计需求,研究了尾舵不同展开速率、不同攻角状态展开以及尾舵展开前后的水动力载荷变化规律;通过对尾舵附近速度矢量场、压力场以及尾舵表面压力系数分析,揭示了尾舵不同状态的流体动力载荷变化原因。研究成果对超空泡航行体尾舵展开过程流场特性研究具有重要参考价值,同时为尾舵机性能设计提供了重要设计依据。In the state of navigating covered with liquid fluid,the hydrodynamics loads of the supercavitating vehicle during the deployment process of the tail rudder have an important impact on the stability analysis of the vehicle and the performance design of the tail rudder.In this study,a numerical simulation method for the deployment process of the rudder based on the overlapping grids technology and the concept of relative motion between grid domains is established.Combined with the design requirements of the supercavitating vehicle,the change law of hydrodynamics loads under different deployment rates,attack angles during the deployment process,before and after deployment of the tail rudder are researched in detail.Through the analysis of the velocity vector field,pressure field near the rudder and pressure coefficients of the rudder surface,the reasons for the changes of the hydrodynamic loads in different states are revealed.The results have important reference value for the research on the flow field characteristics of the deployment process of the tail rudder for the supercavitating vehicle,and provide an important design basis for the performance design of the tail rudder.
