Wind-Tunnel Investigation of Effects of Various Aerodynamic Balance Shapes and Sweep Back on Control-Surface Characteristics of Semispan Tail Surfaces With NACA 0009, 0015, 66-009, 66(215)-014, and Circular-Arc Airfoil Sections

Abstract

A summary of force data on unswept and sweptback airplane control surfaces is presented. Lift and hinge-moment characteristics were determined for four unswept, semispan control surfaces, and lift, drag, hinge moment, and pitching moment were determined for two semispan, sweptback control surfaces. These control surfaces were tested in the 9-foot wind tunnel of the Daniel Guggenheim School of Aeronautics at the Georgia Institute of Technology and were of the wide-chord type suitable for use as elevators or rudders. Measured values of the various parameters are compared with those obtained from section data by application of lifting-surface and lifting-line theory.
