<p>The controller comprises a component with a spring element to pre-stress an aerodynamic brake towards a run-in position. Another component has a mass element (5) to move out the aerodynamic brake through a centrifugal force caused through an adequate high rotation of a rotor blade-segment against the pre-stress of the spring element. A third component (7) has an actuator which is connected with the aerodynamic brake and actuated to move out the aerodynamic brake against the pre-stress of the spring element. An independent claim is included for a method for aerodynamic braking in a wind energy system.</p> |
