摘　　要：江海直达船舶在内河水域航行时,由于内河船舶密度高和码头水域狭窄,因此避让及调头作业是最为常见的工况,要求江海直达船舶具有良好的变向操纵性能。船舶的回转性是反映变向操纵性能的重要指标,针对江海直达船的尺度要素和舵参数,采用经验公式对其回转直径进行计算分析,提出了江海直达船舶的舵面积系数建议,并针对不同水域环境条件提出了增加其舵效的有效建议。When sailing in the inland waters, due to the high density of ships and the narrow wharf waters, avoidance and head-turning are to be the most common working conditions, which require the river-to-sea ships to have a good steering performance. As turning ability is an important index to steering performance, turning diameter is calculated and analyzed by empirical formula for the scale factor and rudder parameters of the river-to-sea ships, to propose the suggestions on rudder area coefficient. Meanwhile, according to the different water environment conditions, proposing the effective suggestions to increase the rudder effect.
