Abstract

A wind turbine rotor blade has a first rotor blade segment with a first connection end and a second rotor blade segment with a second connection end assigned to the first end. The first segment has first mounting sleeves at the first end. The first mounting sleeves each have a first internal thread. The second rotor blade segment has second mounting sleeves at the second connection end. Each of the second sleeves define a longitudinal axis and has a second internal thread arranged therein. Each of the second internal threads is displaceable axially with respect to the corresponding longitudinal axes. The rotor blade further has a plurality of connecting bolts threadably engaging a pair of first and second sleeves via corresponding internal threads such that the first segment and the second segment are mechanically interconnected at the first end and the second end.
