<p>PURPOSE: A vertical wind power generator with multiple blades is provided with structural stability as airflow is dispersed to the leading end of the blade so that the moment is not concentrated on one place. CONSTITUTION: As to a vertical wind power generator, two to seven airfoil blades are placed in one blade arm(20). The concave part of a blade(10) is extended toward the outside. The angle of the rotary center shaft with the leading edge of each blade is in a straight line. The angle of the line connecting the leading edge and the trailing edge of a receiving blade is same with the line vertical to the line connecting the rotary center shaft of the blade to the leading end of the blade.</p> |
