Title: Comparative drag measurements at transonic speeds of 6-percent-thick airfoils of symmetrical double-wedge and circular-arc sections from tests by the NACA wing-flow method
Abstract: Report presenting comparative drag measurements at zero lift at transonic speeds for two sharp-leading-edge airfoils using the NACA wing-flow method. One airfoil had a symmetrical circular-arc section and one had a symmetrical double-wedge section. The primary difference in the drag characteristics of the two airfoils at zero lift is the earlier drag rise of the double-wedge section.
