Abstract
The Cascaded Wind Turbine is a new concept of wind turbine design featuring multiple hubs in succession, each hub segment adds another tier that create a cascading blade configuration. Each blade set is connected to a separate rotor via a telescopic shaft.
Claims8
A wind turbine comprising:
- a. a nacelle comprising a first hub and a second hub, said second hub being aft of said first hub and each hub being connected to a rotating shaft;
- b. a plurality of blades connected at one end to either said first hub or said second hub, wherein each of said hubs has at least one of said plurality of blades connected to it;
- c. a generator connected to said rotating shaft;
- and
- d. a stand connected to the bottom of said nacelle;
- wherein said rotating shaft comprises a first telescoping section which telescopes within a second telescoping section, and wherein said first and second telescoping sections rotate independently of one another;
- and wherein said first hub is connected to and rotates with said first telescoping section and said second hub is connected to and rotates with said second telescoping section.

A wind turbine comprising:
- a. a tier-1 rotor hub in connection with a tier-1 rotor shaft, wherein said tier-1 rotor shaft comprises a tier-1 rotor shaft bearing;
- b. a tier-2 rotor hub being aft of said tier-1 rotor hub and in connection with a tier-2 rotor shaft, wherein said tier 1 rotor shaft fits telescopically within said tier-2 rotor shaft, wherein said tier-2 rotor shaft comprises a tier-2 rotor shaft bearing, and wherein said tier-2 rotor shaft rotates independently of said tier-1 rotor shaft;
- c. at least two tier-1 blades connected at the trailing edge of said at least two tier-1 blades to said tier-1 rotor hub;
- d. at least two tier-2 blades connected at the trailing edge of said at least two tier-2 blades to said tier-2 rotor hub;
- e. a tier-1 generator in communication with said tier-1 rotor shaft;
- and
- f. a tier-2 generator in communication with said tier-2 rotor shaft.
