The rotor has, connected with the hub (1), at least two horizontal supports (2) on the ends of which are rotor blades (3) of a symmetrical and concavo-convex aerodynamic profile with the chord lengths (b1, b2) and the thickness of the profile diminishing towards both wing ends (3a, 3b). The upper wing (3a) and the lower wing (3b) of the rotor blade (3) are radially deflected from the central zone (3c) outwards. The length of the chords (b2) of the profile of both wing ends (3a, 3b) and the chord length (b1) in the central zone (3c) are approximately inversely proportional to the radii of its location in relation to the axis of the rotor's rotation. The deflecting angle of the lower wing (3b) can be greater than the deflecting angle of the upper wing (3a) or the length of the lower wing (3b) can be greater than the length of the upper wing (3a). The specification of the rotor gives a uniform intensity of consuming wind power at the length of the wings and generally in the support only tensile stress is generated while the hazard of flutter is practically eliminated. |
