Patent ID: 8629570

Claim:
A blade assembly for a horizontal-axis wind turbine rotor comprising: a central rotor hub having a central axis and a rotor hub shaft; said rotor hub shaft having a portion extended in a front of said central rotor hub and another portion extended in a rear of said central rotor hub; a plurality of blades mounted on said central rotor to rotate through a plane of rotation, each of said blades lying along a blade axis and having a proximal end radially extended from said central rotor and a distal end outwardly extending to define a blade surface between said proximal end and said distal end, wherein said blade surfaces are arranged in such a manner that when an air flow exerts on said blade surfaces, said central rotor is driven to rotate for generating a rotational power to a power generator; a plurality of rods or cables of equal size, made of a rigid hard or flexible material; each end of a first group of said plurality of rods or cables of equal size connecting with each other to form a plurality of frames; each corner of a first frame of said plurality of frames fixedly or movably attached to said blade surface of one of said plurality of blades; each one end of a second group of said plurality of rods or cables of equal size fixedly or movably attached to each said corner of said first frame and each other end of said second group of said plurality of rods or cables of equal size fixedly or movably attached to said front extended portion of said rotor hub shaft.
