摘　　要：文中介绍了NF-3风洞二元实验段侧壁边界层吹除控制系统及实验方法,以GAW-1翼型为例,给出了不同吹气系数对风洞边界层的控制效果,研究了附面层吹除法对单段翼型和多段翼型实验结果的影响规律。结果表明,该控制系统能有效地改善翼型表面的流动特性。The blowing control system of sidewall boundary layer in the NF-3 wind tunnel two dimensional sections and testing method were introduced, and the effects of the controlling of the sidewall boundary layer in the NF-3 wind tunnel by changing the blowing coefficients were given. Taking the GAW-1 airfoil model as example, the effect of airfoil testing with the blowing control system was studied. It shows that this blowing control system is able to improve the 2D flowing character.
