<p>A rotor for collecting energy from or for imparting energy to a flowing medium has a hub and at least one rotor blade (10). In order to develop such a rotor so that its efficiency, both for collecting energy from and for imparting energy to a flowing medium, be improved, the rotor blade (10) has at least one aerodynamic or hydrodynamic corrugation that forms two edges (14, 16) with the flat part of the rotor blade. The edge (14) located in the radial direction of inflow is inclined by an angle α with respect to the normal to the rotor blade edges (22, 24), so that this edge, with regard to the rotor blade edge being in the direction of rotation, is outwardly oriented, whereas the other edge (16) is perpendicular to the rotor blade edges (22, 24).</p> |
