WIND TURBINE BLADE |
| 摘要 |
The present wind turbine blade comprises an airfoil structure comprising an airfoil shape, an internal support structure arranged spanwise along the length of the blade within the airfoil structure, and an elastic connection joining a portion of an inner surface of the airfoil structure with a portion of the internal support structure. The airfoil structure can be passively pitched relative to the internal support structure according to aerodynamic pressure distribution at different blade locations. |

1. A wind turbine blade comprising:
an airfoil structure comprising an airfoil shape; an internal support structure arranged spanwise along a length of the blade and within the airfoil structure; and an elastic connection joining a portion of an inner surface of the airfoil structure with a portion of the internal support structure, wherein the elastic connection is adapted to cause the airfoil structure to passively pitch relative to the internal support structure according to an aerodynamic pressure distribution at different locations of the blade section. |
