To analyze the aeroelastic effects, the numerical analysis of a flexible oscillating airfoil is described, where the structural subsystem is developed including the interaction effects of the fluid flow. The flexible and flapping airfoil is analyzed using well validated fluid and structural simulation codes to find proper motion parameters.
