ABSTRACT:
Wind power engine having a rotor (1) which is rotatable about a vertical axis and has at least three rotor blades (A, B, C) arranged substantially radially which subdivide the rotor (1) into equisized sectors. To improve the characteristics and the efficiency of the wind power engine the rotor blades (A, B, C) are vertically subdivided into several sub-blades (3, 4, 5) and between the sub-blades (3, 4, 5) vertical gaps (6) are arranged for the passage of air. In cross-section said sub-blades (3, 4, 5) are dish-shaped or trough-shaped, the end regions of the sub-blades being angles or bent oppositely to the direction of rotation of the rotor through about 30.degree..
