ABSTRACT:
A rotor blade for a wind energy installation, in which the rotor blade (22) is formed in a plurality of parts, preferably in two parts, with respect to the rotor blade longitudinal direction, in particular in order to temporarily reduce the longitudinal extent of the rotor blade (22) during rotor blade transportation, such that the individual rotor blade segments (24, 26) can be fitted to one another, one behind the other in the longitudinal direction, for assembly of the rotor blade (22), such that in each case at least two rotor blade segments (24, 26) can be connected to one another such that they cannot rotate or such that they can rotate with respect to one another, with the individual rotor blade segments (24, 26) each having one or more suitable contact surfaces (28, 30) which rest directly or indirectly on one another in the assembled state of the rotor blade (22), and such that at least one of the individual rotor blade segments (24, 26) can be tensioned by means of a tensioning apparatus, which can preferably be controlled and/or regulated, in the direction of the rotor center of a wind energy installation (10), and/or can be attached indirectly or directly in a stressed manner to another rotor blade segment (24, 26) and/or to the blade connection and/or to the hub (20) and/or to some other component of a wind energy installation (10).
