Abstract: A blade root cover segment suitable for fitting to a wind turbine blade to span a gap between the blade and a spinner cover. The blade root cover segment includes a first end and a second end and further includes a curved flange for abutting against a correspondingly curved surface of the wind turbine blade; a cover wall extending radially from the flange; and a tensioning band associated with the flange. The tensioning band includes a first end proximate to the first end of the blade root cover segment and a second end proximate to the second end of the blade root cover segment. The first end and the second end of the tensioning band include connection means for connecting with and applying tension between a like blade root cover segment. A blade root cover and a method of assembling a blade root cover are also provided.

Abstract: A blade root cover segment suitable for fitting to a wind turbine blade to span a gap between the blade and a spinner cover. The blade root cover segment includes a first end and a second end and comprises: a curved flange for abutting against a correspondingly curved surface of the wind turbine blade; a cover wall extending radially from the flange; and a tensioning band associated with the flange. The tensioning band comprises a first end proximate to the first end of the blade root cover segment and a second end proximate to the second end of the blade root cover segment, and wherein the first end and the second end of the tensioning band include connection means for connecting with and applying tension between a like blade root collar segment. The invention also encompasses a blade root cover comprising a plurality of blade root cover segments. The invention also extends to a method of assembling a blade root cover from a plurality of blade root cover segments.
