The blade-vortex interaction (BVI) phenomenon is essential to the study of rotorcraft aerodynamics and aeroacoustics. The numerical simulation of BVI has been a challenging one for the fact that most of the numerical techniques either tend to alter the characteristics of the vortex before interaction occurs or are not able to capture all the fluctuations of the aerodynamic coefficients. Large Eddy Simulation in spite of their computational cost is able to preserve the characteristics of the vortex and to capture all the fluctuations of the aerodynamic coefficients which are of critical importance for the Fluid-Structure Interaction investigation. Aeroelastic response of an idealized airfoil to BVI phenomenon is computed using a single degree of freedom (SDOF) mass/spring model. Copyright
