Abstract
A wind turbine comprising a rotor mounted in a housing, aero-foil blades on the rotor extending in cantilever fashion forwardly of the rotor to be parallel to the axis of the rotor. The blades carry at their free ends a rotatable fairing of aero-foil section so that the blades are situated at the center of lift of the aero-foil section so that the air flows through the blades to the area of lower air pressure.
Claims14
A fluid turbine unit to deliver power extracted from a moving fluid, the turbine having a turbine wheel mounted for rotation about an axis parallel to the fluid flow, a plurality of cantilever vanes mounted on said turbine wheel and extending to forward vane ends, an inlet fairing mounted for rotation adjacent the forward vane ends of said vanes, said inlet fairing having a cross-section which provides an aero-foil section such that fluid flowing over the outside of the inlet fairing is accelerated relative to the fluid flowing into the turbine, said vanes being situated in a passage through the aero-foil section at a position corresponding generally to the center of lift of the aero-foil section whereby the fluid flows through the passage to the lower pressure area of the aero-foil section to act on the turbine vanes.
