The invention relates to an aerodynamic auxiliary means (1) for a rail vehicle (2), comprising at least one flow flap (3, 3a) which is pivotably arranged about an axis of rotation (4) between two end positions, wherein the movement between the end positions can be brought about by the action of force of the inflowing air, said flow flap (3, 3a) forming a flow separation edge in a first end position and said flow flap (3, 3a) leaving the inflowing air substantially unaffected in a second end position. |
