Power producing spinner for a wind turbine |
| 摘要 |
A power producing spinner (28) for a wind turbine (10), the wind turbine (10) having a plurality of blades (18) interconnected about an axis of rotation (30) by a hub (20). The power producing spinner (28) includes an aerodynamic shape (34) extending radially outward from the axis of rotation (30) to define an upwind airfoil portion (40) disposed upwind of an inboard portion (42) of each blade (18) of the wind turbine (10). The power producing spinner (28) is effective to extract energy from an air flow (44) flowing over the spinner (28) and to increase an aerodynamic efficiency of the blades (18). |

1. A power producing spinner for a wind turbine, the wind turbine having a plurality of blades interconnected about an axis of rotation by a hub, the power producing spinner comprising:
an aerodynamic shape disposed over at least a portion of the hub and extending radially outward from the axis of rotation to define an upwind airfoil portion disposed upwind of an inboard portion of each blade of the wind turbine; and a mechanical attachment at a distal end of each of the upwind airfoil portions securing the distal end of each of the airfoil upwind portions about a respective one of the blades; wherein the power producing spinner is effective to extract energy from an airflow flowing over the spinner and to increase an aerodynamic efficiency of the blades. |
