摘要：
The invention further relates to a wind turbine blade comprising at least one device for modifying the aerodynamic surface or shape of the blade. The device is connected to a drive system for operating the device, and the drive system is arranged such that it is drivable by a pressure difference across the drive system. In one embodiment of the invention the wind turbine blade further comprises a number of conduits guiding a flow of air between an outer surface of the wind turbine blade and the drive system. The invention further relates to a method for operating an aerodynamic device for modifying the aerodynamic surface or shape of a wind turbine blade comprising the steps of exploiting a pressure difference across a drive system, inside or around the wind turbine blade in providing operating power for operating said device.
