Measuring loads on wind turbine blades
The invention relates to a sensor system for measuring aerodynamic loads acting on a wind turbine rotor blade. The measured aerodynamic loads can be converted to an angle of attack of the resulting wind which flows past the moving rotor blade. The sensor is realised as a trailing edge flap which is...

| description | The invention relates to a sensor system for measuring aerodynamic loads acting on a wind turbine rotor blade. The measured aerodynamic loads can be converted to an angle of attack of the resulting wind which flows past the moving rotor blade. The sensor is realised as a trailing edge flap which is elastically moveable relative the main part of the wind turbine blade. By measuring motion of the trailing edge flap or corresponding motions of components of the sensor system, the aerodynamic forces acting on the blade can be determined. Due to the relative small dimensions of the sensor flap and the relative small displacements of the flap, the sensor system only affects the aerodynamic properties insignificantly. |
