In the JAXA transonic wind tunnel, some wall interference correction methods were investigated in the past, but they were not made practicable. And so, we have offered uncorrected wind tunnel data to users. We developed the wall interference correction method to improve the reliability of the wind tunnel data and to offer them to users, in which we used the measured lift and drag coefficient and the restriction parameter in the panel method that was used in the NASA wind tunnel. The validity of this method was checked by the comparison with the analytical method of images and the comparison with the wind tunnel wall perturbation velocity distributions measured in the validity wind tunnel test. As a result, we confirmed that this method was practical and the approximation of the elliptical lift lord distribution and the wake position did not have a significant influence on the correction quantity.
