毂帽鳍作为一种良好的水动力节能装置，对螺旋桨有着较为明显的节能效果。本文采用基于诱导速度的面元法，以KP505螺旋桨为研究对象，与实验值进行对比发现面元法预报程序计算精度较高，验证了程序的可行性，是一种毂帽鳍螺旋桨快速设计和性能预报的有效手段；对影响毂帽鳍的3个参数进行变参数分析和参数优选。计算结果表明，鳍桨相位角对螺旋桨水动力性能的影响较小，而毂帽鳍直径、毂帽鳍与螺旋桨的轴向间距在合适的范围内尽可能小，能够提高毂帽鳍的节能效果。
Propeller boss cap fins(PBCF) as a good hydrodynamic energy-saving device, has obvious energy-saving effect on propeller. Based on induced velocity surface panel method, KP505 propeller is used as the research object. Comparing with the experimental values, it’s found that the prediction program of this method has nice calculation accuracy, and the feasibility of this program is verified，which can provide data for the design of PBCF, and also has a certain value for the performance prediction of PBCF.The results show that the phase Angle between propeller and boss cap fins has little effect on the hydrodynamic performance of the propeller, and the diameter of boss cap fins and the axial spacing of propeller and boss cap fins is as small as possible,which can improve the energy-saving effect.
