Abstract
The present invention presents a structure for a set of cable-stayed blades for variable-speed wind turbines with the aim of manufacturing low-cost, large-capacity wind turbines with blades of up to 200 meters long, do not rotate to change the tilt of the wing, insulated from turbine shaft, the structure includes the steel tube at the center of the central hub for affixing the blade set onto the head of the wind turbine shaft, a tower to extend the turbine vertical axis for mounting stay cables which are fastened to the axial bearing blade frame, the blade body consists of a triangular prismatic frame with two rear-framing tubes parallel to each other to form the baselines for mounting blade surface sheets which can be furl/unfurled, the blades can be disassembled and placed into containers to be transported to the base of the turbine tower for assembly.
