BLADE FOR AEROGENERATOR

摘要

The present invention relates to a bidirectional blade for a wind power generator, more specifically, to a bidirectional blade for a wind power generator which comprises a main wing and a sub-wing, wherein the main wing has a symmetric airfoil type section and the sub-wing is soft, has a flat plate shape, and protrudes from the outside of a rear end of the main wing to enable a blade to rotate in the same direction regardless of a wind direction and smoothly rotate despite soft wind and strong wind, thereby drastically increasing power generating efficiency and drastically reducing noise occurring when the blade rotates.
