Title:
HORIZONTAL SHAFT WIND POWER GENERATOR USING AN AIRFOIL BLADE HAVING THE SAME WIDTH AND THICKNESS
Document Type and Number:
WIPO Patent Application WO/2013/042937
Kind Code:
A9
Abstract:
The present invention relates to a wind power generator, and more particularly, to a horizontal shaft wind power generator which uses an airfoil blade having the same width and thickness to improve power generation efficiency and operation efficiency of the power generator by using a rotation force due to a lift force generated when wind contacts the blades. To solve the conventional problems described above, the present invention includes: a tower vertically installed on the ground; a nacelle rotatably connected to an upper end of the tower with respect to the vertical shaft; a rotor shaft-coupled to the nacelle; and at least one blade coupled so as to have a pitch angle with respect to an outer surface of the rotor. The blade has an airfoil shape with the same width and thickness to generate a rotation force via the lift force with respect to a region toward a tip of the blade.
