Abstract
This invention relates to an airfoil modifying device, a wind turbine blade and a method of modifying an airfoil profile of the wind turbine blade. The airfoil modifying device comprises a deformable element connected to a filler element, both configured to deform between a retracted position and an extended position. The airfoil modifying device is passively deformed by the local air pressure acting on the blade surface and thus the airfoil modifying device.
