Abstract

This invention relates to a vertical shaft wind turbine, and particularly to an installation method of blades that can effectively improve the efficiency of a vertical shaft wind turbine. A supporting plane is connected to vertical shaft and a blade is installed on supporting plane. The airfoil of the blade is an asymmetrical camber airfoil. The convex surface of blade is installed facing the vertical shaft. The blade rotary angle is in the range of 0-15 degrees. This invention represents a remarkable progress in the field of wind power generation and is applicable industrially.
