<p>A wind power engine with no housing has a rotor (2) rotatable around a vertical axis (1) with at least three substantially radial rotor blades (3, 4, 5, 6) which subdivide the rotor (2) into equally sized sectors. The rotor blades (3, 4, 5, 6) are vertically subdivided in several leaves (7) and vertical gaps (8) for the passage of air are arranged between the leaves (7) of the blades. In order to improve the efficiency and the properties of this wind power engine and to simplify the manufacture of the rotor, two leaves (7, 7') are spaced apart in each rotor blade (3, 4, 5, 6) in such a way that the space between said leaves (7, 7') narrows in the manner of a funnel in the direction of the vertical gap (8) from the side opposite to the direction of rotation of the rotor (2).</p> |
