Considerations of the Total Drag of Supersonic Airfoil Sections

Considerations of the Total Drag of Supersonic Airfoil Sections

Date: July 1947
Creator: Ivey, H. Reese & Klunker, E. Bernard
Description: The results of calculations of the viscous and pressure drags of some two-dimensional supersonic airfoils at zero lift are presented. The results indicate that inclusion of viscous drag alters many previous results regarding the desirability of certain airfoil shapes for securing low drags at supersonic speeds. At certain Reynolds and Mach numbers, for instance, a circular-arc airfoil may theoretically have less drag than the previously advocated symmetrical wedge-shape profile; although under different conditions, the circular-arc airfoil may have a higher drag.
