Actuation mechanisms for load management devices on aerodynamic blades

A wind turbine comprising:

• a hub;
• and
• a plurality of wind turbine blades connected to and arranged about the hub, wherein at least one wind turbine blade of the plurality of wind turbine blades comprises an actuator for actuating an air deflector on the at least one wind turbine blade, wherein the actuator comprises:
• a motor;
• one or more crank arms coupled to the motor at a first end of the one or more crank arms;
• and
• one or more connecting links, wherein a first end of the one or more connecting links is pivotally coupled to a second end of the one or more crank arms, and wherein a second end of the one or more connecting links is pivotally coupled to the air deflector;
• wherein when the motor turns in a first direction the air deflector is configured to extend from the at least one wind turbine blade, and wherein when the motor turns in a second direction opposite the first direction the air deflector is configured to retract into the at least one wind turbine blade.
