ENHANCING STIFFNESS OF WIND TURBINE BLADES

摘要

Edgewise stiffness of a wind turbine blade is enhanced by arranging a tension element between anchor points at the ends of a load bearing member in the turbine blade such as a spar or a beam. The tension element is spaced away from the load bearing member on the trailing edge side of the load bearing member by struts and acts as a suspension cable. Several tension elements may be used and a similar tension element may be arranged on the leading edge side of the load bearing member.
