Root-End of a Wind Turbine Blade

Abstract

The root-end of a blade of a wind turbine contains at least two segments. The segments contain a connection mechanism for their connection to build up the root-end. The segments contain a first segment section, which is prepared for a connection with fiber reinforced components of the blade. The segments contain a second segment section, which is prepared for a connection with a hub of a wind turbine or which is prepared for a connection with pitch-components of a wind turbine.

         12 . A root-end of a blade of a wind-turbine, comprising:
 a plurality of segments,   each of the plurality of segments comprise
 a connection mechanism to connect to an adjacent segment of the plurality of segments in order to form the root-end, 
 a first segment section, which is prepared for a connection with fiber reinforced components of the blade, 
 a second segment section, which is prepared for a connection with a hub of a wind turbine or which is prepared for a connection with pitch-components of a wind turbine. 
   
     
     
         13 . The root-end according to  claim 12 , wherein each of the plurality of segments is a pre-casted component. 
     
     
         14 . The root-end according to  claim 12 , wherein the connected segments of segments root-end form a circular-shaped diameter. 
     
     
         15 . The root-end according to  claim 12 , wherein the root-end comprises six segments. 
     
     
         16 . The root-end according to  claim 12 , wherein the root-end comprises four segments. 
     
     
         17 . The root-end according to  claim 12 , wherein the root-end comprises two segments. 
     
     
         18 . The root-end according to  claim 12 , wherein the adjacent segments are connected by a screw connection. 
     
     
         19 . The root-end according to  claim 12 , wherein the adjacent segments are connected by a dowel connection. 
     
     
         20 . The root-end according to  claim 12 , wherein each of the plurality of segments includes a hole used for the connection of the adjacent segments. 
     
     
         21 . The root-end according to  claim 12 , wherein each of the plurality of segments contain a plurality of resin channels as an integral part. 
     
     
         22 . The root-end according to  claim 12 , wherein the first segment section is shaped like a wedge to achieve a smooth transition zone between the fiber reinforced components of the blade and the segment. 
     
     
         23 . The root-end according to  claim 12 , wherein the plurality of segments of the root-end are positioned on a mould, which is used to support the segments and other blade components for an applied VARTM-process to manufacture a wind turbine blade. 
     
     
         24 . Root-end according to  claim 23 , wherein a fiber reinforced material is arranged and/or placed around the plurality of segments, thereby making the plurality of segments an integral part of the blade. 
     
     
         25 . A blade of a wind-turbine, comprising:
 a segmented root-end according  claim 12 .
