【摘要】 作者以8154型、8101型和876型拖网渔船为对象,根据全年生产情况,从快速性、拖曳性能和经济性能,综合研究其螺旋桨设计工况。由34种型桨的研究结果表明:采用普通桨的拖网渔船,拖网航速为最佳设计工况;采用导流管定距桨的渔船,5节航速为最佳设计工况。更多还原

【Abstract】 In this paper, the design of the propeller in various working conditions of the trawler is discussed. On the basis of the daw of the annual working conditions the performances of speed and trawling and the economic benefits of the trawler-type 8154, type 8101 and type 876 are discussed. In this comprehensive study, 34 diverse propellers have been examined. The results show that the trawlers with conventional propeller get its optimum working condition at trawling speed. And those with fixed-blade ducted propellers reach their optimum at 5 knots.更多还原
