| Abstract: | The research on test technique of aerodynamic characteristics of wind turbine airfoil at high angle of attack is carried out in the two-dimensional test section of NF-3low speed wind tunnel in the Northwestern Polytechnical University.For the wall interference for airfoil wind tunnel test at very high angle of attack from-180°to＋180°,the improved wall pressure message method（IWPMM）for wall interference correction of airfoil wind tunnel test is put forward.It is shown from test results that the airfoil test technique developed in this paper and the wall interference correction method put forward are fit to airfoil test at very high angle of attack. |
