Abstract

The present invention provides a wind turbine having an increased efficiency. The top portion or roof of the wind turbine has an opening and the profile of the top portion induces a downward component to the velocity of the wind, causing it to enter into the opening and increasing the wind intake. A wind deflector device may be added above the wind turbine to force more wind to enter into the opening.

Claims

AMENDED CLAIMS received by the International Bureau on 03
October 2008 (03.10.2008)
L A wind turbine rotor of the type having a top portion and base between which blades are attached, said rotor comprising: a. an opening in said top portion; b. said top portion comprising means to induce a downward movement to said wind, causing it to enter into said opening.
2. The wind turbine rotor of claim 1, wherein said inducing means include an aerodynamic profile.
3. The wind turbine rotor of claim 2, wherein said aerodynamic profile is an airplane Wing like profile.
4. The wind turbine rotor of claim 2, wherein said profile has a first edge which is rounded.
5, The wind turbine rotor of claim 4, wherein said profile has a second edge which is sharper than said first edge,
6. The wind turbine rotor of claim 5, wherein one of said edge slopes towards the center of said opening to create a ventury effect
7, The wind turbine rotor of claim 3, wherein said inducing means comprises a plurality of wing airplane like profiles spaced apart from each other.
8. The wind turbine rotor of claim 3, wherein said inducing means comprises a plurality of spaced segment which together form an airplane wing like profile,
9, The wind turbine rotor of claim 7, wherein wind is forced to go through said spaces.
10. The wind turbine rotor of claim 8, wherein wind is forced to go through said spaces,
- 8 -
11. The wind turbine rotor of claim 3, wherein said inducing means comprises a plurality of at least partially superposed airplane wing like profiles spaced apart from each other.
12. The wind turbine rotor of claim 11, wherein wind is forced to go through said spaces.
13. The wind turbine rotor of claim I5 wherein said inducing means comprises a wind deflector attached to said wind turbine over said opening, said wind deflector forcing wind to enter into said opening.
14. The wind turbine rotor of claim 13, wherein said Wind deflector rotates with said wind turbine rotor.
15. The wind turbiαe rotor of claim 13, wherein said wind deflector device does not rotate with said wind turbine rotor.
16. A wind deflector for a wind turbine, said wind turbine rotor having a top portion having itself an opening, wherein said wind deflector comprises a curved profile to deviate said wind into said opening and said wind deflector does not rotate.
17. The wind deflector of claim 16, wherein said wind deflector is attached over said opening.
18. A wind deflector for a wind turbine, said wind turbine rotor having a top portion having itself an opening, wherein said wind deflector comprises a curved profile to deviate said wind into said opening and said wind deflector rotates with said wind turbine rotor.
