Abstract

A system for a tower segment of a tower is presented, wherein the tower segment is configured for forming at least partially a part of a tower for carrying a structure, in particular for supporting a nacelle of a horizontal-axis wind turbine or a machine house of a vertical-axis wind turbine. The system is configured to be attached, arranged, and/or mounted to the tower segment and comprises at least an airflow manipulation arrangement and a support arrangement. The airflow manipulation arrangement includes an airflow manipulator which is configured for affecting an airflow around the tower segment. The support arrangement is configured for supporting the airflow manipulation arrangement and for mounting the airflow manipulation arrangement to the tower segment. The airflow manipulation arrangement and the support arrangement are configured such, when mounted to the tower segment, that the airflow manipulator projects a tower diameter in radial direction by at least 5%, in particular at least 10%, preferred at least 15%, in particular not more than 30%, further in particular not more than 20%, of the tower diameter, or that the airflow manipulator is essentially parallel to the tower segment. By this, an effective measure against vortex shedding effects is put in place.
