Low-Speed Tests of Five NACA 66-Series Airfoils Having Mean Lines Designed to Give High Critical Mach Numbers
Abstract
An investigation was made of the possibility of developing an airfoil to carry lift without decreasing critical Mach number below that of basic thickness form at zero lift. By designing mean line to carry load over portions of airfoil section having low induced velocities, an effective design lift coefficient of approximately 0.1 was obtained for several airfoil sections without causing maximum predicted critical Mach number to be appreciably less than critical Mach number for basic thickness form at zero lift.
