Abstract
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.
