端板螺旋桨设计及水动力性能分析

Analysis and Research on Tip Loaded Propeller

端板螺旋桨自出现以来,表现出强劲的市场竞争力。本文针对消拖两用船的综合舵桨系统,用升力线方法对端板螺旋桨进行设计,并采用计算流体力学方法(CFD)预报了该螺旋桨水动力性能。与常规螺旋桨对比,端板螺旋桨对螺旋桨推力有积极影响。

CLT(Contracted and Loaded Tip)propeller has showed a strong market competitiveness since its appearance.Taking a towing and tugging ship’s rudder propeller system as research object,this paper designs a CLT propeller based on lifting line theory,forecasts the hydrodynamic performance by CFD and compares it with conventional propeller.The results show that the CLT propeller have a positive effect on propeller thrust.
