It is desirable that an airpiane couid exert its optimum aerodynamic performance by deforming the wing section to be suitable to the flight conditions. In this paper is presented an analytical calculation of the large deformation of a biconvex wing section and the experiment to confirm the calculated result. The experiment was carried out in a wind tunnel on the biconvex wing model being hollow and of which the outer surface is composed of two elastic curved thin plates. The wing surface is deformed through change of the difference between the outside pressure and the inside pressure of the wing in the air flow by adjusting the inside pressure. The good agreement is obtained between the analytical results and the experimental ones for the contours of the deformed wing sections.
