ROTOR BLADE MOLD, METHOD OF MANUFACTURING A ROTOR BLADE FOR A WIND ENERGY INSTALLATION, AND A WIND ENERGY INSTALLATION
A rotor blade mold and a method for manufacturing a rotor blade for a wind energy installation, wherein the rotor blade includes a blade root and a blade tip and wherein the rotor blade extends in a longitudinal direction from the blade root to the blade tip. The mold includes a first rotor blade mold segment adapted for manufacturing a portion of the rotor blade that includes the blade root, a second rotor blade mold segment adapted for manufacturing a portion of the rotor blade that includes the blade tip, and at least a third rotor blade mold segment adapted to be integrated in the rotor blade mold between the first mold segment and the second mold segment, and/or to be removed from the rotor blade mold and thereby lengthen or shorten the rotor blade mold in the longitudinal direction.
