Corrugated panel for wind power generator blade

Abstract

A corrugated panel for a wind power generator blade is provided. The corrugated panel for a wind power generator blade includes: a plurality of wrinkles that are coupled to one surface or the other surface of the wind power generator blade having an airfoil transverse section and that are formed in a length direction of the blade, wherein a gap and a height at a predetermined position of the plurality of wrinkles each have a value of a predetermined ratio to a chord length of the airfoil transverse section of the blade at the predetermined position, when the plurality of wrinkles are coupled to the blade.

1 . A corrugated panel for a wind power generator blade, the corrugated panel comprising:
 a plurality of wrinkles that are coupled to one surface or the other surface of the wind power generator blade having an airfoil transverse section and that are formed in a length direction of the blade,   wherein a gap and a height at a predetermined position of the plurality of wrinkles each have a value of a predetermined ratio to a chord length of the airfoil transverse section of the blade at the predetermined position, when the plurality of wrinkles are coupled to the blade.   
     
     
         2 . The corrugated panel of  claim 1 , wherein the corrugated panel covers an entire width of one surface of the blade from one end portion to the other end portion of the blade and is coupled to the entire width of one surface of the blade. 
     
     
         3 . The corrugated panel of  claim 1 , wherein the corrugated panel is made of a material comprising one of a titanium alloy, an aluminum alloy, and a synthetic resin. 
     
     
         4 . A corrugated panel for a wind power generator blade, the corrugated panel comprising:
 a panel body having one surface that is coupled to one surface or the other surface of the wind power generator blade having an airfoil transverse section; and   a wrinkle portion that has a plurality of wrinkles in a length direction of the blade at the other surface of the panel body,   wherein a gap and a height at a predetermined position of the plurality of wrinkles each have a value of a predetermined ratio to a chord length of an airfoil transverse section of the blade at the predetermined position, when the panel body is coupled to the blade.   
     
     
         5 . The corrugated panel of  claim 4 , wherein the panel body covers an entire width of one surface of the blade from one end portion to the other end portion of the blade and is coupled to the entire width of the one surface of the blade. 
     
     
         6 . The corrugated panel of  claim 4 , wherein the transverse section of the wrinkle has one shape of a polygon, a semicircle, and an oval. 
     
     
         7 . The corrugated panel of  claim 6 , wherein the wrinkle has a transverse section of a triangle shape. 
     
     
         8 . The corrugated panel of  claim 4 , wherein the predetermined ratio is 0.1 to 5%. 
     
     
         9 . The corrugated panel of  claim 4 , wherein the panel body and the wrinkle portion are made of a material comprising one of a titanium alloy, an aluminum alloy, and a synthetic resin. 
     
     
         10 . The corrugated panel of  claim 4 , wherein the panel body comprises a foldable connection portion that is positioned between the wrinkles. 
     
     
         11 . The corrugated panel of  claim 1 , wherein the transverse section of the wrinkle has one shape of a polygon, a semicircle, and an oval. 
     
     
         12 . The corrugated panel of  claim 11 , wherein the wrinkle has a transverse section of a triangle shape. 
     
     
         13 . The corrugated panel of  claim 1 , wherein the predetermined ratio is 0.1 to 5%.
