【摘要】 本文论述了低转速大直径桨在肥大船上的应用,后体设计成隧道形状,并与大直径桨相匹配。由船模试验得知,桨径由5.78米增大至7.28米和8.39米,转速相应由每分120转降低至80转和60转时,在满载状态下可分别节能8.9％和12.6％。在压载状态下也可获得10％左右的节能效益。更多还原

【Abstract】 This article deals with the application of low revolution large diameter propeller on a large full ship. The afterbodies have been designed in tunnel form to suit the large diameter. It has been found from model testing that by increasing the propeller diamcter from 5.78m to 7.28m and 8.39m, and correspondingly decreasing the revolution per minute from 120 to 80 and 60, power savings of 8.9％ and 12.6％ could be obtained respectively in full load condition. There were also about 10％ savings of power in ballast condition.更多还原
