影响运动帆船比赛迎风航线的主要因素分析

Analysis of the Main Factors Affect the Route during the Leg of the Windward in the Sailing Regatta

为了得到迎风航段航线影响的主要因素,分析了风、流和方位线对迎风航段最佳经济航线选择影响。研究发现,比赛中运动员利用风向变化调整自己的航线,减少航行距离;风力小流速大时对迎风行驶中的帆船位移影响较大,所以流向与流速对比赛中帆船选择迎风经济航线有较大影响;在帆船比赛中迎风方位线上转向点的选择很重要,如果比赛中的帆船高出或者低于迎风方位线,都无形中增加了抵达迎风标志的距离,浪费了时间,这条迎风航线就不经济。本研究为运动员进行迎风航段最佳经济航线选择提供了参考。

In order to get the main factors that affect the route during the leg of the windward,the influence of the wind,current and direction on the optimum route was analyzed.It is found that athletes should adjusttheir routes based on the wind direction to reduce their sailing distance in the regatta;when the wind speed is small and the current speed is large,it has a greater impact on the displacement of the sailing boat during the leg of the windward,so the current direction and speed have a greater impact on the selection of the windward economic route:the selection of turning point on the windward direction line is very important.If the sailing boat is higher or lower than the windward direction line,the distance will increase and there will be more time.This windward route is uneconomical.This study provides a reference for athletes to choose the optimum route during the leg of the windward.
