Vertical axis -type wind turbine, has wings comprising two similar half-wings, where each half-wing comprises leading edge that is formed in round shape to support aerodynamics and leading edge angle that lies within specific range

摘要

The turbine has multiple wings operated in a horizontal plane and comprising two similar half-wings that are symmetrically arranged relative to a rotation axis. Each half-wing comprises a pushing edge and a leading edge, where a difference in aerodynamics between the pushing and leading edges is obtained by a triangular concave form of a section of the wings. The leading edge is formed in a round shape to support the aerodynamics and a leading edge angle that lies within a range of 45-75 degree. The half-wings comprise wing frames (4, 5) that are formed parallel to wing ends (3).
