METHOD AND SYSTEM FOR TENSIONING TENSION FABRICS IN WIND-TURBINE

摘要

A wind blade includes a self-supporting structural framework, having a span-wise member, a plurality of chord-wise members, a fabric skin, and at least one of a stiffener and a mechanical element. The plurality of chord-wise members is coupled to the span-wise member and each chord-wise member and the span-wise member maintains an aerodynamic contour of the wind blade. Further, the fabric skin is disposed over the self-supporting structural framework. The stiffener and/or the mechanical element are coupled to the self-supporting structural framework, and are operable to provide a relative movement to the self-supporting structural framework for adjusting the aerodynamic contour and provide pretension to the fabric skin.

1. A wind blade comprising:
a self-supporting structural framework including: a span-wise member; and a plurality of chord-wise members coupled to the span-wise member, wherein each chord-wise member among the plurality of the chord-wise members and the span-wise member have an aerodynamic contour; a fabric skin disposed over the self-supporting structural framework; and at least one of a stiffener and a mechanical element coupled to the self-supporting structural framework, and is operable to provide a relative movement to the self-supporting structural framework for adjusting the aerodynamic contour and provide pretension to the fabric skin.
