Abstract

The invention relates to a wind turbine blade comprising a blade body, a device for modifying the aerodynamic surface or shape of the blade and movably connected hereto, and operating mechanisms for controlling the position and/or movement of the device. The operating mechanism comprises a compressible pressure chamber arranged in relation to the blade body and the movable device such that the position and/or movement of the device relative to the blade body can be modified by changing the pressure in the pressure chamber thereby causing a change of its cross sectional diameter. The operating mechanisms may be connected to and driven by a pressure reservoir arranged within the wind turbine blade or for example constituted by parts of the blade spar.
