Rotor blades for wind power plants with flow optimized surfaces have surface macro structures with variable element lengths, e.g. lotus leaf or shark's skin micro structures as part of macro structure

摘要

The rotor blades have surfaces with recesses and mounds that increase in size towards the outside, macro structures with variable element lengths, regions without macro structures and areas with a micro structure such as lotus leaves or shark's skin that form part of a macro structure.
