A comparative examination of some measurements of airfoil section lift and drag at supercritical speeds

Gerald E. Nitzberg, Stewart M. Crandall
Nov 1952

Semiempirical correlations of supercritical drag data were made for a family of symmetrical airfoils and for several series of cambered airfoils at small and moderate angles of attack. The correlations are of pressure-drag rise per unit chord length as a function of Mach number.
