    Abstract: A variable-pitch multi-segment blade component comprises multiple blade segments and at least one variable-pitch guiding structure placed outside of the blade segments. The variable-pitch guiding structure comprises a guide rail fixed to one of the two adjacent blade segments and one or multiple guiding elements fixed to another one of the two adjacent blade segments, wherein the guiding elements are constructed to be guided and moved on the guide rail. The guiding element comprises multiple rolling elements. The variable-pitch guiding structure provides guiding and bearing type connection. The two adjacent blade segments are capable of rotating about a pitch axis of the blade segments.
