摘要： A wind turbine rotor blade includes a pressure side and a suction side. At least one airfoil passage is defined through the blade between the pressure side and suction side. A respective cover is configured over the airfoil passage at each of the pressure and suction sides. The covers are actuatable between a closed position wherein the cover is flush with the respective pressure or suction side and an open position wherein the cover moves to open the airfoil passage.

摘要： A rotor blade for a wind turbine is disclosed. The rotor blade may generally include a shell having a pressure side and a suction side. The shell may define an outer surface along the pressure and suction sides over which an airflow travels. The rotor blade may also include a spoiler movable relative to the outer surface between a recessed position and an actuated position. The spoiler may generally be configured to separate the airflow from the outer surface when the spoiler is in the actuated position. Additionally, the spoiler may generally be linearly displaced between the recessed and actuated positions.
