摘要(Abstract):

通过对双头反向对称翼型的实验结果的分析比较 ,得出了构造新型的双头反向对称翼型的基本原则 ,认为选择性能好的原始翼型是设计高效双头反向对称翼型的关键。在相同的最大厚度时 ,原始翼型的头部形状对阻力系数的影响不大。
Two double head anti symmetric airfoils have been proposed and the wind tunnel tests on their lift and drag performances have been carried out. The principle rule in designing this new kind of airfoils was drawn through analysis of the experimental results. It was believed that the key role in designing this kind of double head anti symmetric airfoils is to choose a normal airfoil with high performance and the head shape of the normal airfoils with the same thickness has little influence on the drag coefficient of this kind of new airfoils.
