Note (General): Static pressure distributions on the upper and lower walls of the NAL 2m×2m transonic wind tunnel test section and on an airfoil model in it were measured at 0,6 and 20％ open area ratios of the walls.One of the experiments was carried out at only 20％ open area ratio in 1978 and another one was made at 0 and 6％ in 1980 and the other one was also made at 6 and 20％ in 1981.The pressure distributions measured during the experiment in 1978 were almost equal to those in 1981 at 20％ open area ratio of the walls but those at 6％ in 1980 and 1981 were different.The aerodynamic characteristics of the upper and lower perforated walls changed with the change in open area ratio but the manner of change differed.The differences among the slopes of lift coefficient curves corresponding to various open area ratios still remained after they were corrected with the correction method using wall pressure measurements.More accurate experiments on the aerodynamic characteristics of the tunnel walls are needed to clarifyancies.
