For a hydropower machine having at least one blade wheel (1), which has a rotatably supported hub (13) that carries a plurality of blades (18) and which can be installed in a flowing body of water, in particular a channel, in such a way that the blade wheel (1) forms a damming element with the hub (13) of the blade wheel so that a damming level (14) is produced on the upper-water side, an electrical generator (4) is coupled, optionally by means of an interposed gear train, to the rotation of a shaft connected to the hub (13). The cross-section of the blades (18) that extends in the tangential direction of the blade wheel (1) has at least one curved area. |
