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.
