By calculating and comparing the aerodynamic performance of elliptic airfoils with different thickness-chord ratio using numerical calculation method,the 16% thickness elliptic airfoil is selected to be the experimental airfoil,and the experimental investigation on this airfoil is performed in two-dimensional testing section of NF-3 wind tunnel at Northwestern Polytechnical University.
为对椭圆翼型的低速气动特性进行研究,通过不同相对厚度椭圆翼型气动特性的数值计算和分析比较,选取16%相对厚度椭圆翼型作为试验翼型,在西北工业大学NF-3风洞二元试验段内对此翼型的低速气动特性进行了试验研究,试验采用表面测压和尾排型阻测量技术。
