Wind-Tunnel Investigation at Low Speed of an Unswept Untapered Semispan Wing of Aspect Ratio 3.13 Equipped with Various 25-Percent-Chord Plain Flaps

Abstract

Force and moment data were obtained at low speeds to determine the aerodynamic characteristics of an unswept untapered semi span wing of NACA 64A010 section and aspect ratio 3.13 equipped with 25-percent-chord unsealed plain flaps having various spans and spanwise locations. Lift, drag, pitching-moment, and flap hinge-moment data were obtained for the wing with the various flaps deflected up to 600.
