Low speed aerodynamic characteristics of a 17 percent thick airfoil section designed for general aviation applications

Robert McGhee, W. D. Beasley, Dan M. Somers

Abstract

Wind-tunnel tests were conducted to determine the low-speed section characteristics of a 13 percent-thick airfoil designed for general aviation applications. The results were compared with NACA 12 percent-thick sections and with the 17 percent-thick NASA airfoil. The tests were conducted ovar a Mach number range from 0.10 to 0.35. Chord Reynolds numbers varied from about 2,000,000 to 9,000,000.
