The present paper presents the modal analyses of a NACA 4415 airfoil. Theoretical and numerical calculations are performed by considering the air craft wing as a cantilever beam. The model is created and modal analyses are performed by using commercially available packages of SolidWorks and Ansys, respectively. The natural frequencies and the related mode shapes are obtained. The results of theoretical calculations are compared with the numerical modal analyses. The results show that by ignoring the whole forces on a plane (except for gravity), a plane wing can be considered as a cantilever beam.
