The present invention is directed to a venturi rotor apparatus for producing power from the rotation thereof. The apparatus comprises a support and a central core having a spherical triangular cross-section mounted on the support for rotation about a central axis through the core. A plurality of support arms, fixed to the central core, extend radially outward therefrom at the verticies of the spherical triangle. At least three airfoils are fixed to a radially extended portion of the support arms such that a gap is formed between the surface of the central core and the surface of the airfoils, with the airfoils being aligned on an axis parallel to the axis of the central core. Fluid flow, such as air flow, having at least a component in the direction perpendicular to the axis of the central core flows through the gap producing a venturi effect for enhancing the movement of the airfoils about the axis of the central core. The movement of the airfoils applies torque to the central core through the support arms to thereby rotate the central core. The central core includes an output which rotates with the central core and which can be used as a power takeoff from the rotating central core.

A venturi rotor apparatus as set forth in claim 1, wherein said central core means has a spherical-triangular cross-section, said support arms radially extending from the verticies thereof. 3. A venturi rotor apparatus as set forth in claim 2, wherein said central core means has an inner, circular cross-section, said inner portions and outer surface being rigidly connected together. 4. A venturi rotor apparatus as set forth in claim 1, wherein said trailing edge of said airfoil means is knife edge. 5. A venturi rotor apparatus as set forth in claim 4, wherein said leading edge of said airfoil means is an arc of a circle. 6. A venturi rotor apparatus as set forth in claim 1, wherein said leading edge of said airfoil means is an arc of a circle. 7. A venturi rotor apparatus as set forth in claim 1, wherein said support arms extend from both ends of said central core means. 8. A venturi rotor apparatus as set forth in claim 1, wherein the central axis of said central core means is vertical. 9. A venturi rotor apparatus as set forth in claim 2, wherein the width of each said gap is substantially equal to the maximum width of each said airfoil means. 10. A venturi rotor apparatus as set forth in claim 2, wherein the width of said gap and the maximum width of each said airfoil means is equal to the distance from the central axis to the verticies of said airfoil means. 11. A venturi rotor apparatus as set forth in claim 2, wherein a line from said trailing edge of one of said airfoil means to the adjacent vertex of said central core means is parallel to a line from the central axis of said central core means to the axis of said airfoil means. 12. A venturi rotor apparatus as set forth in claim 1, wherein each said airfoil means is pivotally mounted on said support arms. 13. A venturi rotor apparatus as set forth in claim 12, wherein each said airfoil means includes means for biasing said airfoil means against centrifugal force resulting from the rotation of said apparatus. 14. A venturi rotor apparatus as set forth in claim 13, wherein said central core means comprises a plurality of modular units rigidly coupled together and wherein each said airfoil means includes a plurality of modular units rigidly coupled together. 15. A venturi rotor apparatus as set forth in claim 1, wherein said central core means includes a shaft means extending therefrom for providing as power output for said venturi rotor apparatus.
