Et vindenergianlægs rotorblad og tilsvarende fremgangsmåde

摘要

The blade (1) has a hub fastener (17) for fastening the blade at a hub of a wind energy plant. A radially outwardly running air guidance channel (23) is arranged inside the blade to guide sucked air from a suction region (21) to the blowing out region. A rear edge (15) in a root portion (11) of the blade is provided at an obtuse angle in a portion along the blade. The suction region is arranged at the rear edge and/or a top face (13) of the root portion, and the blowing out region is arranged in a blade tip (12). The suction- and blowing out regions are formed as holes and/or slots i.e. teeth. An independent claim is also included for a method for controlling power of a wind power plant.
