Keywords: ground effect aerodynamics, airfoil, hot-wire anemometry, turbulence

Results from an experimental investigation of aerodynamic ground effect on three airfoils, NACA 0015, 4415 and 6415, carried out in a low speed wind tunnel are presented. The pressure distribution on the airfoil surface was obtained from pressure tappings. Mean velocity measurements were performed over the surface of the airfoil and velocity contours were plotted.
