A novel electro-magneto-aeroelastic energy harvester is proposed employing the single degree of freedom flutter mechanism, in which a free pitching airfoil is augmented with an inductive energy harvesting system made by a permanent magnet attached to the airfoil and a fixed coil. Due to stall aerodynamics in divergent motion after the onset of flutter, such a system will exhibit nonlinear flutter phenomenon, such as LCOs, which can be used to generate energy by the induction effect. To address such a physical problem in energy harvesting, a nonlinear electro-magneto-aeroelastic system model is developed, taking the stall aerodynamics nonlinearity and the electromechanical coupling into account. With given parameters, the nonlinear electro-magneto-aeroelastic behaviour is studied by the time domain simulation approach. A preliminary study reveals the nonlinear aeroelastic behaviour and energy harvesting performance of the present aeroelastic energy harvester.
