Abstract: PURPOSE: A blade assembly for a wind power generator is provided to confirm the optimum time for cleaning a blade by checking the pollution level of the blade. CONSTITUTION: A blade assembly for a wind power generator comprises a blade(120), a first probe(130), a second probe(140), and a data acquisition system. The first probe is installed between one end of the blade and the thickest part, and measures a change in a fluid flow. The second probe is installed between the other end of the blade and the thickest part of the blade, and measures the change in the fluid flow. The data acquisition system converts a measured value into voltage so that the measured value is formed into a graph.
