Abstract
A Cycloidal Turbine Power Generator contained within a Venturi is disclosed. The Venturi is equipped with mechanisms to vary its inlet width to control flow volume through the Venturi, and to open and close the inlet as required. The Venturi is also equipped with inflatable turbulators installed upstream from the turbine, and which extend upward from the Venturi bottom to cause a downstream eddy to reduce drag on the advancing blades of the turbine. The turbine includes a plurality of airfoil-shaped blades mounted to vary their angle of attack during rotation of the turbine. The rotation of the blades about the common hub is caused by the action of the water flow over the blades. A ring gear may be fixed to the circumference of the blade disk for power generator interface.
