An Evaluation of the Characteristics of a 10-Percent-Thick NACA 66-Series Airfoil Section With a Special Mean-Camber Line Designed to Produce a High Critical Mach Number
Abstract
The mean-camber line of an airfoil may be so designed that the induced velocities resulting from the camber will occur over that part of the airfoil chord along which the induced velocities resulting from the basic thickness form are small. Thus, by a proper combination of mean line and basic thickness form, the critical Mach number of a cambered airfoil may be increased above that usually predicted for an airfoil cambered with a more conventional-type mean line such as the a = 1.0.
