Windmill generating station with box low-pressure radial-flow fan (3) having through an inlet opening a preliminary reducer (1) to the speed increase of the intake flowing air. The reducer (1) by its tapered end corresponds by the shape and the dimension to the inlet opening of the radial-flow fan (3), wherein the cross section of the enlarged end of the reducer (1) is 1.1 to 10 times greater than the cross-sectional area of the tapered end. With a vertical situated axis of the radial-flow fan (3) is mechanically linked an electric generator (4). The reducer (1) is connected to a mechanical swivelling (2) against the wind, which is situated between the radial-flow fan (3) and the electric generator (4). |
