【摘要】 文章通过船模试验研究了水线面大开口型工程船的静水阻力和波浪阻力特性。结果显示,水线面大开口型工程船的艏艉开槽大大增加了船体的静水阻力,但对船体波浪增阻的影响却并不明显。同时,用模型试验和实船试验共同验证了此类船舶航行时双舵内偏一个角度能明显提高航速,是一项有效的节能措施。更多还原

【Abstract】 In this paper the still water resistance and wave resistance performance of work ships with notches are studied by model tests.The results show significant increase in still water resistance when there are notches in bow and stern,but no obvious effect on wave augmented resistance.Both model test and full scale test prove that twin rudders deflecting certain angle when this kind of work ships sail can improve the speed significantly.It is an effective energy-saving measure.更多还原
