摘　　要：为了提高轮缘推进器的推进效率,考虑对来流进行预旋和整流作用,提出一种安装在导管前侧的一阶等差桨前定子式附体。基于CFD数值计算方法,对轮缘推进器和前置定子组合系统进行敞水性能数值模拟,其计算结果与常规轮缘推进器敞水性能数值结果对比表明,加装一阶等差桨前定子式附体组合系统的推进效率最高可达到3%的性能提升。In order to improve the propulsive efficiency of the rim-driven thruster,a new type attachment of first-order equal difference stators proposed in this paper,which is installed at the front side of the conduit,considering the pre-swirling and rectification effects on the incoming flow.Based on the CFD numerical calculation method,the open-water performance numerical simulation of the combined system of rim-driven thruster and front stator is carried out,the numerical results of open-water performance is compared with the conventional rim-driven thruster and shows that the propulsive efficiency of the combined system with first-order equal difference stator can be improved up to 3%.
