Wind turbine electric generator

Patent ·
OSTI ID:5390480
A wind-operated electric generator system of simple design including a stationary circular arrangement of segmental wind inlet passages extending around a vertical axis and having vertical inlet openings at the outer ends, the inlet openings having inwardly and upwardly curving walls extending from the inlet openings toward the central axis, the lower walls sloping upwardly an appreciably greater extent than the upper walls to form an inwardly and upwardly extending convergence with the inner portions of the upper walls to form constricted upwardly directed exit passages that merge into a Venturi throat in which a bladed impeller is mounted upon a vertical shaft which is connected to an electric generator, and the sides of the segmental inlet passages also converging toward the central axis and cooperating with the converging upper and lower walls to form an efficient Venturi effect to increase the speed of air currents directed to the impeller.
