Abstract

The invention generally relates to turbines that efficiently process air or fluid flow while producing substantially no vibrational effects. In certain embodiments, the invention provides a turbine including a rotatable shaft, and at least one blade connected to the rotatable shaft, in which the blade includes a helical shape and an angle of about 180° or greater.

Claims (20)

1. A turbine comprising:
a rotatable shaft; and at least one blade connected to the rotatable shaft, wherein the blade comprises a helical shape and has an angle of about 180° or greater.
2. The turbine according to claim 1, wherein the blade further comprises a helical shape.
3. The turbine according to claim 1, wherein a leading edge of the blade comprises a bulbous portion.
4. The turbine according to claim 1, wherein a trailing edge of the blade comprises a winglet.
5. The turbine according to claim 1, wherein a leading edge of the blade comprises a bulbous portion and a trailing edge of the blade comprises a winglet.
6. The turbine according to claim 1, wherein a cross section of the blade is shaped as an airfoil.
7. The turbine according to claim 1, wherein the blade comprises an angle of about 270° or greater.
8. The turbine according to claim 1, wherein the blade comprises an angle of about 360° or greater.
9. The turbine according to claim 1, wherein an interior of the blade comprises a foam core and an exterior of the blade a shell made from a material selected from the group consisting of carbon fiber, fiberglass composite, metal, and polymeric.
10. The turbine according to claim 1, wherein the turbine is operably connected to a generator.
11. A turbine, the turbine comprising:
a rotatable shaft; and a plurality of blades connected to the rotatable shaft, wherein each blade comprises a helical shape and the blades are twisted to such a degree that vibrational effects from rotation of the blades are substantially eliminated.
12. The turbine according to claim 11, wherein a leading edge of the blade comprises a bulbous portion.
13. The turbine according to claim 11, wherein a trailing edge of the blade comprises a winglet.
14. The turbine according to claim 11, wherein a leading edge of the blade comprises a bulbous portion and a tailing edge of the blade comprises a winglet.
15. The turbine according to claim 11, wherein a cross section of the blade is shaped as an airfoil.
16. A wind turbine, the turbine comprising:
a rotatable shaft; and a plurality of blades connected to the rotatable shaft, wherein each blade comprises a helical shape and the blades are twisted to such a degree that the blades rotate about the shaft at a speed greater than the actual wind speed.
17. The turbine according to claim 16, wherein a leading edge of the blade comprises a bulbous portion.
18. The turbine according to claim 16, wherein a trailing edge of the blade comprises a winglet.
19. The turbine according to claim 16, wherein a leading edge of the blade comprises a bulbous portion and a tailing edge of the blade comprises a winglet.
20. The turbine according to claim 16, wherein a cross section of the blade is shaped as an airfoil.
