Abstract

The invention relates to a rotor (1) through which a fluid flows in a main direction of flow (H) and which is provided with at least one rotor blade (4), said rotor blade being arranged in such a way that it can rotate about a rotor axis. The rotor blade (4) extends away from the axis of rotation (2), into the fluid, at least in sections. The rotation (D) of the rotor blade (4) about the axis of rotation (2) in a predetermined direction of rotation produces a propulsive thrust in the opposite direction to the main direction of flow, or a torque is produced about the axis of rotation as a result of the flow. The aim of the invention is to reduce the trailed tip vortex at the end of the rotor blades of rotors of this type and therefore to reduce the fluidic losses and flow noise. To this end, the rotor blade (4) extends in at least two partial blades (5, 6) at a set distance from the axis of rotation and forms a loop. One partial blade (5) extends in the direction of rotation (D) in relation to the rotor blade, at least in one area close to the rotor blade. The other partial blade extends in the opposite direction to the direction of rotation (D) in relation to the rotor blade (4), at least in one area close to the rotor blade (4). The two partial blades (5, 6) are interconnected in one piece at their ends so that they encompass a loop surface (12) through which the fluid flows, said loop surface extending essentially crosswise to the main direction of flow.
