Abstract
The effectiveness of a passive control system, namely, the Nonlinear Energy Sink (NES) in the control of the response of a nonlinear aeroelastic system is investigated. The system consists of a rigid airfoil elastically mounted on linear and nonlinear springs. The structure equations are derived using Lagrange's equations. The quasi steady aerodynamics are used to model the aerodynamic loads. The NES having linear damping is attached to the aeroelastic system. The parameters of the passive controller are varied in order to investigate the efficiency in supressing undesirable aeroelastic behavior. The results suggest that the nonlinearity of the NES influences the nonlinear dynamic behavior of the aeroelastic system and may yield undesirable responses.
