基于风洞试验的帆翼空气动力性能研究

A Research of the Wing’s Aerial Dynamic Performance Based on Wind Tunnel Test

利用风洞试验进行帆板的空气动力参数是研究风帆性能的重要手段,本文概述了帆翼的空气动力性能的几个特征指标、帆翼模型、试验的方法、风洞试验的控制条件等;并对拱度试验、风向角0°～360°帆翼空气动力性能的试验、帆的前倾、后倾、正扣、反扣七种组合的对比试验结果进行了分析、对帆设计、操作以及航速预测均具有较大的指导作用。

It is an important means to utilize wind tunnel test to measure the wing＇s aerial dynamic parameters and study the wing＇s performance. This paper has summarized several characteristic index showing the wing＇s aerial dynamic performance, model of the wing, methods of testing, the controlling conditions of wind tunnel test, etc; and analyzed the test results of arch test, the wing＇s aerial dynamic performance test at the wind angle from 0 to 360 degrees, seven kinds contrastive tests combining pitch and leaning-back and cover,which may provide helpful directions for the wing＇s design, handling and prediction of velocity.
