wind turbine blade, wind turbine, and method for preventing trailing edge bending of a wind turbine blade

摘要

1/1 summary “Wind turbine blade, wind turbine, and method to prevent trailing edge bending of a wind turbine blade” A wind turbine blade is described comprising a rigid structural component fairing (12) forming the bulk of the aerodynamic profile and a non-actively controllable elastically deformable trailing edge component (14) mounted to the structural component to complete the aerodynamic profile. the trailing edge component (14) is formed of a material having an elastic module in the range of 0.5 to 2.5 gpa so that it flexes elastically when loading on the trailing edge component exceeds a predetermined limit. . The structural member (12) comprises a unidirectional reinforcement layer adjacent the trailing edge component with at least one unidirectional fiber layer (26) extending in a direction substantially in the wingspan.
