| 20110020126 | MODULAR ROTOR BLADE FOR A POWER-GENERATING TURBINE AND A METHOD FOR ASSEMBLING A POWER-GENERATING TURBINE WITH MODULAR ROTOR BLADES - A modular rotor blade for a power generating turbine allows simple replacement of individual rotor blade sections in case of damage to or malfunction of a section. The modular rotor blade includes at least two rotor blade sections, wherein each rotor blade section includes at least one connecting part having at least one conical opening. The connecting parts of adjacent rotor blade sections rest against each other such that the conical openings of the connecting parts are aligned with each other and form a continuous conical connecting opening. Receiving elements for receiving tensioning elements are arranged at the smaller diameter end of the conical connecting opening. A conical bolt corresponding to the continuous conical connecting opening is arranged therein, and at least one tensioning element passes through the conical bolt and tensions the conical bolt against the receiving element. | 01-27-2011 |
| 20080253892 | Tension Wheel Hub in a Rotor System for Wind and Water Turbines - A rotor system for a fluid-flow turbine comprising a hub mounted on a shaft, a plurality of rotor blades, and a tension wheel, the tension wheel comprising a rim structure mounted to the hub by a plurality of spokes. Each rotor blade is attached to the rim structure of the tension wheel. The lost energy in the area of the rotor circumscribed by the tension wheel rim structure is captured by applying airfoils, such as blades or sails, to the spokes of the tension wheel and/or an inner section of the rotor blades. | 10-16-2008 |
