【摘要】 研究开发性能优良的舵型,改善舵的水动力性能,对提高船舶操纵性十分重要。对某28000DWT MPC轮设计了制流板舵,并采用CFD软件FLUENT分别计算了舵球舵、制流板舵的水动力性能系数,制流板舵的升力系数比舵球舵高约7.1%。根据实船操纵性试验数据对比,在舵叶面积不变的情况下,采用制流板舵比普通舵球舵稳定回转直径减少大约4.3%。制流板舵可有效地减少横向绕流,提高升力和舵效,改善船舶的操纵性能。制流板舵结构简单且基本不增加舵机功率,因此非常适用于船舶的技术改造。更多还原

【Abstract】 The maneuverability of a modern ship is guaranteed by rudders. A good performance rudder is very important for maneuverability of a ship. In this paper, a swash plate rudder is designed for a 28000 DWT MPC, and the hydrodynamic performances of rudder-bubble rudder and swash plate rudder are researched based on CFD software FLUENT. The result shows that lift coefficient of swash plate rudder is about 7.1% higher than that of rudder-bubble rudder. The maneuverability trail shows that the stable turning diameter decreases about 4.3% when swash plate rudder is used. Swash plate can effectively decrease the cross flow and improve the lift, rudder effects and the maneuverability. Because swash plate rudder has a simple structure and almost no need to increase the power of actuator with the same rudder area, swash plate rudder can be widely used for ship technical transformation.更多还原
