Rotor blade for wind power systems

摘要

Rotor blade consisting of fibre reinforced plastics, having a flexurally stiff spar for wind power systems. The rotor blade has a shaped core made from a pressure-resistant foam, which has a central spar part and a front and rear profiled part which are placed against the spar part. Arranged at the two ends of the spar part are deflecting and/or fastening elements over which a unidirectional fibre winding is wound in the direction of the longitudinal axis of the spar. A cross winding rests on the unidirectional fibre winding on the spar part. The rotor blade skin is formed, over the entire shaped core with the shaped part and the front and rear profiled parts placed thereon, by a cross winding deposited thereupon.
