中型公务船艏部型线设计分析探讨

为了在新开发公务船中进行型线优化设计,对两条实船的四种型线裸体船模试验结果进行了分析对比,证实对于方形系数在0.50以下的船型,当Fn为0.40附近时,设球鼻艏增加了有效马力;但在Fn处于0.32～0.35区间时,由于形成有利干扰兴波阻力下降,设倒水滴形球鼻艏能减少有效马力约3％～6％.

Analysis of Middle Official Vessel's Bow Line Design

For optimizing line design of new developed official vessel, this article analysis the 4 ship model test results of 2 existing vessels and confirms a series of conclusions. For the ship block coefficient below 0.50, when the FN value is around 0.40, bulbous bow will increase the effeciency horsepower. When the FN value is among 0.32 and 0.35, bulbous bow will decrease about 3% - 6% effeciency horsepower because of the wave resistance is low down,
