Abstract

There is provided a device for production of electrical, mechanical or hydraulic energy by using wind or other fluid currents. This is achieved by blocking a portion of the flow through an edge positioned wing (1) alone or in combination with a longitudinal wing (2). The invention includes an edge positioned wing (1), a rotor (5), a bottom profile (4), gable profiles/lamellas (3) and turbine lamellas (12) to focus the flow towards the rotor (5). Perforations (10) or gaps (7) in or between the wings may improve the flow through or around the turbine.

Claims

1. Device for production of electrical, mechanical or hydraulic energy by using wind or fluid flow energy, which device includes at least one rotor, where the wind or fluid flow results in the rotor rotating around its axis, at least a bottom profile and at least one wing, wherein:

the rotor is axially connected to a generator, and

the wing is edge positioned, whereby the chord of said edge positioned wing is oriented towards the rotor.

2. Device according to claim 1, wherein the edge positioned wing has a solid or hollow structure.

3. Device according to claim 1, wherein the edge positioned wing is provided with perforations in at least a portion of the wing.

4. Device according to claim 1, wherein the edge positioned wing is edge riffled.

5. Device according to claim 1, wherein the edge positioned wing is prism-shaped, flat, convex, concave or differently flow dynamically designed.

6. Device according to claim 1, wherein the edge positioned wing is oriented at an angle between perpendicular to the rotor rotation axis and tangentially to the outer periphery of the rotor.

7. Device according to claim 6, wherein the device further comprises at least one suspension means on which the edge positioned wing is mounted, wherein the suspension means comprises a rotation axis around which the edge positioned wing can rotate.

8. Device according to claim 1, wherein the device further comprises at least one longitudinal wing located between said edge positioned wing and said rotor, said longitudinal wing being oriented with its chord essentially perpendicular to the rotor.

9. Device according to claim 8, wherein the longitudinal wing is integrated into the edge positioned wing.

10. Device according to claim 8, wherein the longitudinal wing, in relation to the wing cross section is prism-shaped, flat, convex, concave or adapted the periphery of the rotor.

11. Device according to claim 1, wherein the rotor is designed as a vertical, horizontal, propeller or screw turbine.

12. Device according to claim 1, wherein the device further comprises at least one lamella located in a turbine flow channel bounded by the edge positioned wing and the bottom profile.

13. Device according to claim 1, wherein the cross section of the bottom profile is flat, curved, or aerodynamically adapted to the periphery of the rotor.

14. Device according to claim 1, wherein the device further comprises at least one turbine lamella located in the turbine flow channel.

15. Device according to claim 1, wherein two or more edge positioned wings are oriented with their chords against the rotor.
