Abstract: A hybrid type vertical shaft turbine (1) for wind power generating devices, includes a supporting structure (2) supporting, concentrically and axially spaced, an internal rotor (3) made of Savonius blades (4) and an external rotor (5) made of Darrieus blades (6), wherein the shaft (7) has the bottom end (12) which may be connected to an electric generator for transforming wind energy into electric energy, wherein both the internal Savonius rotor (3) and the external Darrieus rotor (5) have twisted blades with identical or different values in the axial direction of the turbine. The Savonius blades extend between end flanges (8, 9) to radial arms (10, 11) equispaced in each flange (8, 9) and offset between the flanges (8, 9) to accommodate the external Darrieus blades. The proposed twistings allow considerably improving the continuity of the driving torque generated with the wind velocity increasing towards medium-low, medium and medium-high velocities and vice versa.
