  • Wind turbine blades with tension fabric skin structure
    Patent number: 9188102
    Abstract: A wind blade with a self-supporting structural framework, 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 have an aerodynamic contour. The wind blade also comprises a fabric skin located over the self-supporting structural framework in a tensioned state to generate an aerodynamic surface, wherein the fabric skin is attached via multiple tensioning members to both the chord wise members and span wise members.

  • WIND TURBINE ROTOR BLADE WITH FABRIC SKIN AND ASSOCIATED METHOD FOR ASSEMBLY
    Publication number: 20140119937
    Abstract: A rotor blade for a wind turbine includes an internal support structure extending span-wise from a blade root to a blade tip. A plurality of ribs are fixed to and spaced along the internal support structure, with each rib extending in a generally chord-wise direction and having a generally aerodynamic blade contour. A plurality of chord-wise oriented fabric strips are affixed to the ribs in a tensioned state, wherein the fabric strips define an aerodynamic outer skin of the rotor blade.

  • MULTIWALL SHEET, METHODS OF MAKING, AND ARTICLES COMPRISING THE MULTIWALL SHEET
    Publication number: 20130017361
    Abstract: A multiwall sheet can comprise walls, wherein the walls include: a first wall; a second wall; and a transverse wall, wherein the first wall, the second wall, and the transverse wall extend longitudinally; and a rib extending between adjacent walls, wherein a layer is formed by two adjacent walls; wherein the layer is filled with a nanoporous foam material; and wherein the multiwall sheet comprises a normalized thermal conductivity value of less than or equal to 1.00 W·m/kg·K. A method of making a multiwall sheet can comprise coextruding the multiwall sheet described above with a nanoporous foam material; wherein the layer is filled with a nanoporous foam material during coextrusion.
