The variation of the coefficient of drag with the coefficient of lift for a wing or wing-body combination at subcritical Mach numbers is expressed as two straight lines intersecting at a lift coefficient. A mathematical model is developed to show the relationships of these aerodynamic coefficients. The effects of wing section, planform, Mach number, and Reynolds number are analyzed. The data are based on wind tunnel tests of wings and wing-body combinations in which the wings have conventional airfoil sections. (Author)
