Abstract

A rotor blade and a method and a manufacturing mold for the production of a rotor blade for a wind turbine, which extends longitudinally in the operational state from a blade root area to the connection to a rotor hub of the wind turbine and which is divided into at least two segments for its production, wherein at least one subdivision is provided approximately transverse to its longitudinal extension between the blade root area and the blade tip. The method facilitates and shortens the production of the rotor blade, in particular for a series production and to still provide the completed rotor blade as a familiar uniform rotor blade. In the method, the at least two segments, preferably after they have been at least partially produced or partially produced mainly parallel in time, are interconnected in an integration device.
