Abstract

The present invention relates to a rotor (3) blade (2) with aerodynamic flow static diverter (1), in particular blade (2) for vertical axis aeolic rotor (3), characterised in that said aerodynamic flow static diverter (1) is fixedly coupled with said rotor (3) blade (2), said diverter (1) being positioned inside with respect to said rotor (3), close to the blade (2) leading edge, and having an aerodynamic shape extending substantially parallel with respect to the profile portion of said blade (2) corresponding, and faced toward, the same diverter (1).
