An experiment on wall interference caused by the lift with two-dimensional wings, was carried out in the NAL 2m × 2m transonic wind tunnel with perforated walls, at high subsonic speeds. The open area ratios of upper and lower test section walls were set at 20％. Two airfoil models were used. In this experiment, pressure distributions near the upper and lower walls inside the test section were also measured, in addition to the pressure distribution on an airfoil model. Various quantities of lift interference with two-dimensional wings were assessed by a new method. This method was proposed in a previous paper, by one of the present authors, and requires only the measurement of pressure distributions on flow boundaries. Lift interference parameters, δ0 and δ1, for the present case, were evaluated indirectly by this method.
