This paper describes both the flow field around an airfoil and the aerodynamical properties of the airfoil subjected to the ground effect. The Reynolds number was 1.2×10<SUP>4</SUP>. Our attention was primarily focussed on pressure measurement on a ground plate. Some specific features of the pressure distribution were clarified. We attempted to evaluate lift acting on the airfoil by performing surface integral of the pressure on the ground. Two types of end plates were tested as a preliminary experiment. The results obtained were anticipated: the pressure tends to become higher as an end plate has such shape as to decrease the spanwise velocity component over the airfoil. The results of the measured pressure distribution were found, in general, to reflect strongly enough the features of the flow field visualized by the smoke wire method.
