A wing of a human-powered airplane is generally constructed with foam, balsa wood, plastic film and CFRP to achieve light-weight structure. Thus, the structure can be bent and deformed easily. The change of the wing shape may cause the performance degradation. In this study, we physically built the deformed wing model to measure the deformation by using 3D scanner. CFD was used to investigate the influence of the deformation of airfoil on aerodynamic performance in cruise condition through the comparison with original shape. As a result, the deformation causes the fluctuation of pressure distribution, and it also deteriorates the aerodynamic coefficient.
