Wind turbine blades with tension fabric skin structure

摘要

A wind blade 28 with a self-supporting structural framework 60, having multiple chord-wise members and one or more span-wise members is provided. Each of the multiple chord-wise members and the one or more span-wise members 62 have an aerodynamic contour. The wind blade also comprises a fabric skin 50 located over the self-supporting structural framework in a tensioned state to generate an aerodynamic surface, wherein the fabric skin 50 is attached via multiple tensioning members to both the chord wise members and span wise members 62.
