摘要
基于已有的单参数线化壁压信息法,在做相应简化改动后应用于旋翼翼型高速试验数据修正,着力解决工程上遇到的旋翼翼型高速风洞试验结果不理想的问题。文中采用该方法对FL-21风洞得到的OA309旋翼翼型试验数据进行了修正。结果表明,修正后的旋翼翼型气动特性曲线与国外已有结果吻合较好。该方法能有效满足旋翼翼型高速风洞试验修正的需要。
In order to improve the results of high speed wind tunnel test of rotor airfoil in engineering, the existing single parameter linear wall pressure method is simplified and applied to the data correction. The simplified method is used to correct the OA309 rotor airfoil test data in FL-21 wind tunnel. Comparison resuhs show that the modified aerodynamics performance curves of rotor airfoil are in good agreement with the abroad data. The method can effectively meet the requirement of data correction of high speed wind tunnel test of rotor airfoil.
