A SYSTEM AND A METHOD FOR WIND ENERGY CONVERSION INVOLVING THE OSCILLATORY MOTION OF AN AIFOIL-LIKE WING

The method for generating electric energy provides for: A) generating induced electric currents resulting from the reciprocating motion of a magnet built into a pivot (220, 230) and a coil (523, 533); the magnet (220, 230) or the coil (523, 533) is fixed and respectively the coil (523, 533) or the magnet (220, 230) moves along a trajectory (420, 430), B) carrying out a motion of a mobile wing (200) having a wing surface (210) and a rotational axis (R), and impinged by a fluid flow (F); the axis (R) is constrained permanently to a fixed structure (310, 321, 322, 331, 332) through at least one elastically extensible element (323, 333), so that when the wing surface (210) is impinged by the fluid flow (F), the wing rotates, thereby performing oscillations about the axis (R) and the axis (R) translates, thereby performing oscillations along the trajectory (420, 430); the magnet is associated to the fixed structure (310, 321, 322, 331, 332) and the coil is associated to the mobile wing (200) or the coil (523, 533) is associated to the fixed structure (310, 321, 322, 331, 332) and the magnet (220, 230) is associated to the mobile wing (200).
