A wind turbine (100) comprising: a support frame (101), a shaft (102) rotatably associated with the support frame (101) according to a substantially vertical rotation axis (Z), an electric generator (103) mechanically connected to the shaft (102), a plurality of arms (104) integral with the shaft (102), a plurality of monolithic blades (105) configured to intercept the thrust of the wind so as to put the shaft (102) into rotation about the rotation axis (Z) according to a rotation direction (S), each of which: is hinged to a respective arm (104) according to a hinge axis (U) perpendicular to the rotation axis (Z), is delimited in the transverse direction to the hinge axis (U) by a first edge (106), which is proximal to a successive blade (105) of the plurality of blades (105) with respect to the rotation direction (S), and a second edge (107) which is distal from said successive blade (105), and rotates with respect to the hinge axis (U) between a rest position, in which the distance is minimum between the first edge (106) and the hinge axis (U) of the successive blade (105) with respect to the rotation direction (S) of the shaft (102), and an active position, in which the distance is maximum between the first edge (106) and the hinge axis (U) of the successive blade (205) with respect to the rotation direction (S) of the shaft (102); said wind turbine (100) also comprising a plurality of elastic elements (112), each interposed between a blade (105) and the corresponding arm (104) and configured to exert a force on the respective blade (105) which promotes the movement of said blade (105) from the active position to the rest position.
