description abstractA wind-tunnel investigation was made at low speed to determine the aerodynamic characteristics of a 45° sweptback untapered semispan wing of NACA 64A010 airfoil section normal to the leading edge and aspect ratio of 1.59 equipped with 25-percent-chord plain unsealed 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 60°. A comparison is made with data obtained on the present wing at 0° of sweep with an aspect ratio of 3.13.
