Abstract
Provided is a method of manufacturing at least a portion of rotor blade for a wind turbine, the method including: casting at least a portion of an rotor blade outer surface using a casting material thereby at least partially embedding at least one fluid convey tube into the casting material, the 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.
Claims19
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.
A rotor blade of a wind turbine, comprising:
- a cast rotor blade outer surface formed by crosslinked casting material;
- and
- at least one fluid convey tube embedded into the crosslinked casting material;
- wherein the at least one fluid convey tube is provided for conveying fluid into or out of a deformable container for adjusting an adjustable flow regulating device of the rotor blade;
- wherein the cast rotor blade outer surface includes an opening located a distance along the cast rotor blade outer surface from the deformable container, the at least one fluid convey tube being connected to the deformable container located externally along the cast rotor blade outer surface by a linking tube that extends along the cast 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;
- and
- 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.
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;
- wherein the at least one fluid convey tube is closed with a plug at one or both ends during the casting of the casting material.
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;
- wherein the at least one fluid convey tube comprises a plurality of fluid convey tubes having different lengths and arranged parallel to each other side by side, further wherein the different lengths are selected such as to correspond to a distance between a respective longitudinal position of a segment of the flow regulating device and a rotor blade root.
