Device for a rotor blade of a wind turbine

摘要

The invention relates to a device (30) for decreasing the roughness sensitivity of a rotor blade (20) of a wind turbine (10). The device (30) comprises an attachment section (31) by which it is arranged and prepared for being attached to a surface (23) of the rotor blade (23). The device (30) furthermore comprises a flow guiding plate (32) and connection means (33) which connect the attachment section (31) with the flow guiding plate (32). The flow guiding plate (32) comprises an upstream section (34) and a downstream section (35), whereby the upstream section (34) and the downstream section (35) are defined with regard to the direction of the airflow (42). The distance between the upstream section (34) and the surface (23) of the rotor blade (20) is different compared to the distance between the downstream section (35) and the surface (23) of the rotor blade (23). Additionally, the invention relates to a rotor blade (23) of a wind turbine (10) comprising at least one such device (30).
