摘　　要：采用FLUENT软件对带超空泡航行体尾舵的空化特性进行了数值仿真研究,研究表明,楔角越小舵的升阻比越大,同楔角下复合型舵的升阻比要高于楔型舵的升阻比;小空化数下舵的舵效要好于大空数下的舵效;攻角的增加舵的阻力系数曲线先不上升然后上升.The drag characteristics of wedges-shaped fin are effected by different attack angles, cavitation numbers and angles of wedge-shaped fin. The data are obtained by using FLUENT. The fin with rear body could provide higher efficiency at small cavitation number and angles of wedge-shaped fin. The obtained results show that curve of drag eoefficient does not ascend at beginning, then ascends with the increased flow angle.
