FIELD: power engineering.
SUBSTANCE: invention relates to a structural element of a tail end of a blade, to a blade of a wind power plant containing such a structural element, and to a method for manufacturing such a blade. The specified structural element of the tail end contains fastening elements distributed along the tail end of part of the blade, wherein there are pultrusion elements between fastening elements. Each pultrusion element has the second side surface facing the first side surface of an adjacent fastening element. Between the specified first and second side surfaces, at least in the direction along the thickness, there are gaps that provide the possibility of adjustable location of pultrusion elements relatively to outer layers during the resin infusion using vacuum.
EFFECT: reduction in the formation of folds in the transition area between inner and outer sheathings, and increase in the operational flexibility when placing holding elements.
