| Abstract: | A wind tunnel experiment on a kind of single sail model that is named Dragon Ridge Sail has been conducted. The mean and fluctuating coefficients of drag and lift of the model in various wind directions and pitch angles were obtained through high frequency base balance technique. These results provide references to similar sail shaped constructions in engineering applications. |

| Keywords: | wind load high frequency base balance drag coefficient lift coefficient |
