Abstract
A wind generator is disclosed in which superconducting ring generators are utilized without the need for a load bearing drive shaft and other mechanical components, decreasing overall weight and enabling the use of variable geometry blades for increased overall efficiency.
Claims22
A wind turbine ring generator apparatus comprising:
- a stationary, ring-shaped stator
- a ring-shaped rotor concentrically disposed relative to the ring-shaped stator about a common axis and separated therefrom, the ring-shaped rotor having an interior diameter and at least one rotor blade extending across a portion of the interior diameter and attached to the ring-shaped rotor so that rotor blade and ring-shaped rotor move in unison relative to the ring-shaped stator.
A wind turbine apparatus comprising:
- a stationary, ring-shaped stator
- a ring-shaped rotor concentrically disposed relative to the ring-shaped stator and separated therefrom,
- a plurality of rotor blades operatively coupled to the ring-shaped rotor and extending radially outward therefrom so that rotor blades and ring-shaped rotor move in unison relative to the ring-shaped stator.
A rotor blade apparatus comprising:
- a rotor blade having a cross-sectional profile defining a perimeter shape;
- and
- a mechanism operatively coupled to the rotor blade for selectively manipulating at least a portion of the perimeter shape of the cross-sectional profile to modify the aerodynamic characteristics of the rotor blade.
