摘　　要：基于现有风帆助航船舶的设计方案,根据横向力系数和推力系数随拱度比的变化趋势选定风帆参数,并设计了可折叠帆面、双列布置的风帆方案,解决风帆助航船舶风帆装置对甲板空间占用过大的问题,风况不利、船舶进出港以及装卸货物时亦可实现良好的收帆效果。以80000t船为例检验该设计方案对船体稳定性的影响,得出了该新型风帆设计方案可有效降低燃油消耗实现船舶节能减排,并满足船舶安全要求的结论。Based on the current Sall-asb＇t^t~u ueoti^l~, ,,,~ y force coefficient and thrust coefficient. Based on the analysis results, a new sail program, in which collapsible sails are arranged in double rows, is designed which can release deck space and sails can be folded up when wind conditions get bad. Then, the 8000t bulk carriers are used as an example to analyze the stability of the boat with this new sails. Conclusions can be obtained that this new design can reduce fuel consumption.
