Airflow modifying assembly for a rotor blade of a wind turbine

A method and assembly 30 for aligning airflow modifying elements on a rotor blade 22 is disclosed. The airflow modifying assembly 30 may be mounted onto a suction side surface or a pressure side surface of the rotor blade 22. Further, the airflow modifying assembly 30 includes an alignment structure 38 having a chord-wise extending face 44 that may be fixed relative to the rotor blade 22 at a predetermined position. The airflow modifying assembly 30 further includes a first base 32 having a root end 39, a tail end 46 having an interconnecting profile 42, and a first plurality of airflow modifying elements 40. The root end 39 is aligned with the chord-wise extending face 44 such that the first base 32 extends span-wise along the rotor blade 22. Additionally, the airflow modifying assembly 30 includes at least one second base 34 having a connector end 48 with a complementary interconnecting profile 42 and a plurality of airflow modifying elements 40, wherein the connector end 48 is coupled to the tail end 46.
