采用多重重叠网格技术模拟一对称立式水下潜器在三维回转运动过程中水下潜器系统及其系统中导管螺旋桨的水动力特性，提出一种水下潜器三维回转运动数值计算模型，通过指定叠加运动来控制螺旋桨的旋转来对水下潜器的三维回转运动方式进行操纵。计算结果表明：提出的水下潜器三维回转运动数值计算模型可以预报水下潜器三维回转运动的动力状态；水下潜器在其三维回转运动过程中，导管螺旋桨发出的推力表现出稳定的周期性的变化；相比于二维回转运动，水下潜器在进行三维回转运动过程中，由于垂向运动速度分量的存在，导致水下潜器导管螺旋桨推力较二维回转运动条件下小，潜器主体所受垂向流体阻力较二维回转运动条件下更大且波动更加剧烈。
The multi-level overset mesh method is used to simulate thrust performance of ducted propellers attaching to a symmetrical vertical underwater vehicle by using CFD software STAR-CCM+. A three-dimensional rotary motion mathematical model of underwater vehicles was proposed. We use a user defined function to control the three-dimensional rotary motion and designate an additive motion to control the motion of ducted propellers. Simulation results indicate that: the mathematical model proposed in this paper could achieve a three-dimensional rotary motion of an underwater vehicle; during the motion of three-dimensional rotation, the thrust generated by each ducted propeller tend to be a stable and periodic change; the thrust curve of each ducted propeller is more complex with the influence of the main body of underwater vehicle; compared to without the influence of the main body, and the main factor is the current obstructed by the main body of underwater vehicle.
