【摘要】 在螺旋桨上加装桨毂帽鳍PBCF,是日本近年来开发的一种廉价的节能装置。它能使螺旋桨效率提高3％～7％,并且实船推进效率的收益是模型值的一倍。若在转动导管螺旋桨上加装PBCF,其效果更佳。本文就PBCF对螺旋桨诸性能的影响效果及其使用,进行了较系统地论述与分析。更多还原

【Abstract】 The Propeller Boss Cap Fins (PBCF) is a new Japan—developed device attached to the shaft of propeller. Simple and capable of saving energy, it can increase the efficiency of propeller by 3—7%, twice as much in an actual ship as in a model ship. Attaching it to the shaft of propeller with rotary duct will lead to a better result. This paper is concerned with the influence of PBCF on various performances of the propeller.更多还原
