The invention relates to a novel rotor blade (1", 14', 14") for generating a resulting force (F) onto the longitudinal axis of a rotor blade. The total profile (1", 14', 14") of the rotor blade (2) is substantially composed of a main blade element (15) and an auxiliary blade element (16, 16'), which are arranged one behind the other at a defined gap breadth s in the rotor blade plane (8). Due to the aerodynamic interaction of flows of a flow medium (7), the direction of rotation remains the same independent of the direction of flow. |
