Abstract

A wind turbine rotor blade is disclosed that includes a body extending between a blade root and a blade tip. The body may include a pressure side and a suction side extending between a leading edge and a trailing edge and may define an outer surface. In addition, an ultraviolet light-reflective tape may be disposed on the outer surface of the body.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A wind turbine rotor blade, comprising:
 a body extending between a blade root and a blade tip and including a pressure side and a suction side extending between a leading edge and a trailing edge, the body defining an outer surface; and   an ultraviolet light-reflective tape disposed on the outer surface of the body.   
     
     
         2 . The wind turbine rotor blade of  claim 1 , wherein the ultraviolet light-reflective tape only covers a portion of the outer surface of the body. 
     
     
         3 . The wind turbine rotor blade of  claim 1 , wherein the ultraviolet light-reflective tape defines a pattern along the outer surface of the body. 
     
     
         4 . The wind turbine rotor blade of  claim 3 , wherein the ultraviolet light-reflective tape forms a plurality of stripes extending along the outer surface of the body. 
     
     
         5 . The wind turbine rotor blade of  claim 4 , wherein the plurality of stripes extend in a chordwise direction between the leading and trailing edges of the body. 
     
     
         6 . The wind turbine rotor blade of  claim 1 , wherein at least a portion of the ultraviolet light-reflective tape is disposed along at least a portion of the leading edge of the body. 
     
     
         7 . A wind turbine rotor blade, comprising:
 a body extending between a blade root and a blade tip and including a pressure side and a suction side extending between a leading edge and a trailing edge;   a transparent coating defining an outer surface of the body; and   an ultraviolet light-reflective substance disposed beneath the outer surface.   
     
     
         8 . The wind turbine rotor blade of  claim 7 , wherein the ultraviolet light-reflective substance is disposed between the outer surface and a blade material of the body. 
     
     
         9 . The wind turbine rotor blade of  claim 8 , wherein the ultraviolet light-reflective substance comprises at least one of an ultraviolet light-reflective paint, an ultraviolet light-reflective tape and an ultraviolet light-reflective material. 
     
     
         10 . The wind turbine rotor blade of  claim 7 , wherein the ultraviolet light-reflective substance comprises at least one of an ultraviolet reflector and an ultraviolet brightener. 
     
     
         11 . The wind turbine rotor blade of  claim 10 , wherein the at least one of the ultraviolet reflectors and the ultraviolet brighteners are dispersed within at least one of the transparent coating and a blade material of the body. 
     
     
         12 . The wind turbine rotor blade of  claim 7 , wherein the ultraviolet light-reflective substance defines a pattern beneath the outer surface. 
     
     
         13 . The wind turbine rotor blade of  claim 12 , wherein the ultraviolet light-reflective substance forms a plurality of stripes extending in a chordwise direction between the leading and trailing edges of the body. 
     
     
         14 . The wind turbine rotor blade of  claim 7 , wherein at least a portion of the ultraviolet light-reflective substance is disposed along at least a portion of the leading edge of the body. 
     
     
         15 . A wind turbine rotor blade, comprising:
 a body extending between a blade root and a blade tip and including a pressure side and a suction side extending between a leading edge and a trailing edge; and   an ultraviolet light-reflective substance defining a pattern along at least a portion of the body.   
     
     
         16 . The wind turbine rotor blade of  claim 15 , wherein the ultraviolet light-reflective substance forms a plurality of stripes extending along the at least a portion of the body. 
     
     
         17 . The wind turbine rotor blade of  claim 16 , wherein the plurality of stripes extend in a chordwise direction between the leading and trailing edges of the body. 
     
     
         18 . The wind turbine rotor blade of  claim 15 , wherein the body defines an outer surface, the ultraviolet light-reflective substance being disposed on the outer surface. 
     
     
         19 . The wind turbine rotor blade of  claim 15 , further comprising a transparent coating defining an outer surface of the body, the ultraviolet light-reflective substance being disposed beneath the outer surface. 
     
     
         20 . The wind turbine rotor blade of  claim 15 , wherein the ultraviolet light-reflective substance comprises at least one of an ultraviolet light-reflective paint, an ultraviolet light-reflective tape, an ultraviolet light-reflective material, an ultraviolet reflector and an ultraviolet brightener.
