Abstract
Provided is a blade for a wind turbine, the blade including a joint section configured to connect the blade to a hub of the wind turbine; an active add-on member which is actuated by a corresponding trim actuator to alter aerodynamic properties of the blade; and a channel configured to supply a medium from the joint section to the active add-on member. A wind turbine and a method of preventing icing of the blade is also provided.
Claims14
A blade for a wind turbine, comprising:
- a joint section configured to connect the blade to a hub of the wind turbine;
- an active add-on member which is actuated by a corresponding trim actuator to alter aerodynamic properties of the blade;
- and
- a channel configured to supply a medium from the joint section to the active add-on member.
A method of preventing icing of a blade of a wind turbine, the wind turbine comprising a tower and a rotor, the rotor being mounted at the top of the tower to rotate about a rotational axis, wherein the rotor has the hub and a plurality of blades, wherein each blade comprising a joint section configured to connect the blade to the hub of the wind turbine;
- an active add-on member which is actuated by a corresponding trim actuator to alter aerodynamic properties of the blade;
- and a channel configured to supply a medium from the joint section to the active add-on member, wherein the method comprises a step of guiding the medium through the channel from the joint section to the active add-on member.
