WIND TURBINE BLADE |
| 摘要 |
A wind turbine blade comprising a fairing with a rigid structural component (12) which forms the majority of the aerodynamic profile and a non-actively controllable elastically deformable trailing edge component (14) mounted on the structural component to complete the aerodynamic profile. The trailing edge component (14) is formed from a material having an elastic modulus in the range of 0.5 to 2.5 GPa such it will elastically buckle when loading on the trailing edge component exceeds a predetermined threshold. The structural component (12) comprises a unidirectional reinforcing layer adjacent to the trailing edge component with at least one layer of unidirectional fibres (26) extending in a substantially spanwise direction. |

1. A wind turbine blade comprising a fairing having an aerodynamic profile, the fairing comprising:
a rigid structural component which forms the majority of the aerodynamic profile; and a non-actively controllable elastically deformable trailing edge component mounted on the structural component to complete the aerodynamic profile, wherein the trailing edge component is formed from a material having an elastic modulus in the range of 0.5 to 2.5 GPa such that it will elastically buckle when loading on the trailing edge component exceeds a predetermined threshold, and wherein the structural component comprises a unidirectional reinforcing layer adjacent to the trailing edge component, the unidirectional reinforcing layer comprising at least one layer of unidirectional fibres extending in a substantially spanwise direction. |
