摘　　要：帆船比赛中,起航阶段成功与否是比赛胜负关键之一。通过数值模拟方法得到了不同桅杆形状、不同扣角和倾角以及帆翼外形时帆翼空气动力系数随攻角变化关系。在帆翼空气动力性能数值模拟的基础上,分析发现,帆船起航阶段战术是保证帆船冲击力的关键,如果帆船运动员身体素质较佳,那么在确保帆船平衡的前提下,要调整帆船攻角、桅杆迎风位置、扣角和倾角以及帆船帆翼拱度大小,使得帆船帆翼整体推力性能达到相对较大。如果帆船起航时候占据有利的位置,就要在接下来的迎风航段不断牵制住其他帆船。该文通过探讨帆船起航阶段的调帆基本原则,为帆船运动员在起航阶段调帆争夺到有利位置提供科学指导。The aerodynamic performance of the trimming sail by use of numerical simulation method was studied.The relationship between the sail aerodynamic coefficient and the angle of attack,different mast shapes,angle of the pitch with the direction of the athlete,angle of the pitch with the direction of the stern,different sail shapes was revealed.Based on the weight,height and physical fitness of the athlete,during the leg of the starting,if the athlete would want to go out of the sailing group,the angle of attack change,the mast shape,angle of the pitch with the di rection of the athlete,angle of the pitch with the direction of the stern,different sail shapes could be adjusted to the appropriate degree to have the sailboat fast when the sailboat could be balanced.When the sailboat begins in the race,it should keep from the competitor in the beneficial route if it would be ahead.The basic principles of trim ming sail were analyzed for guiding the players to know how to trim the sails during the leg of the starting in sailing competition.
