ABSTRACT:
The Specification discloses a segmented wind turbine which can be added to incrementally to increase the driving force and power generation of the machine. By this means the smaller diameter rotors that are more easily handled and that put the minimum of stress on the wind turbine apparatus can be used in series to achieve the power output desired. Each segment has a venturi means incorporated into the elements of the apparatus to enhance the apparent wind speed. Also disclosed are novel means for operatively supporting the moving parts of the apparatus.
In a preferred embodiment an exoskeletal frame is made in segments that can be stacked one upon the other. Each segment of frame has arms which converge inwardly toward the axial center of the apparatus. There a hoop connects the ends of the inwardly converging arms and defines an axial aperture. Inside this axial aperture a segment of drive shaft and a concentric collar are supported by thrust bearings which are in turn supported by the concentric hoop attached to the arms of the frame. Each set of arms and the associated bearings support the drive shaft, a rotor on the drive shaft, and a wind shield surrounding the rotor immediately above the arms. The wind shield is of a novel structure, having two spaced side walls which define openings for receiving wind through the rotors and discharging the wind. One of the walls forms a venturi with the rotor.
