1. A method of manufacturing at least a portion of a rotor blade for a wind turbine, the method comprising:
casting at least a portion of a rotor blade outer surface using a casting material thereby at least partially embedding at least one fluid convey tube into the casting material, the at least one fluid convey tube being provided for conveying fluid into or out of a deformable container for adjusting an adjustable flow regulating device of the rotor blade; and
after the casting, forming an opening in the rotor blade outer surface, the opening located a distance along the rotor blade outer surface from the deformable container, and connecting the at least one fluid convey tube to the deformable container located externally along the rotor blade outer surface with a linking tube that extends along the rotor blade outer surface from the opening to the deformable container;
wherein a section of the at least one fluid convey tube is situated completely inside the rotor blade and the section is embedded under the rotor blade outer surface;
wherein the portion of the rotor blade outer surface and a fluid convey tube embedding material are chemically crosslinked with each other in the rotor blade.
