| 摘 要： | 为克服目前风帆助航船风帆面积计算的不足,从船舶稳性角度出发,基于静稳性曲线的稳性裕量,首先从理论上推导出圆弧型风帆面积的估算公式,再结合一艘载质量为48 000 t的散货船,借助Excel工具,用该方法进行风帆面积的估算.经验算发现该方法能满足稳性要求,表明该方法可为大型风帆助航船的风帆面积计算提供参考.

| Abstract: | In order to overcome the shortcomings in the calculation on sail area of existing sail assisted ships, from the perspective of ship stability, based on stability margins of static stability curves, the estimation formula of arc sail area is derived theoretically. Then, with the help of Excel, the method is applied to a bulk carrier with dead weight tons of 48 000 t to estimate the sail area. The calculation shows that it can meet the stability requirement, which implies that the method can provide reference for the calculation on arc sail area of large sail assisted ships. |
