| 摘要： | Several airfoils, including a conventional NACA 23021 and some low- drag airfoils for which the thickness had been increased to the point that they were considered doubtfully conservative with respect to separation, were investigated as smooth airfoils and after the application of a standard roughness. The results show some of the airfoils to be critical to separation resulting from such flow disturbances. It is concluded, pending the further investigation of separation difficulties, that airfoils sections falling definitely within the conservative range should be used. |
