摘要： Joints 100 for connecting a first blade segment 101 to a second blade segment 102 of a wind turbine rotor blade 16 include a first bolt 120 comprising a first proximal end connected to the first blade segment 101 and a first distal end connected to the second blade segment 102, a second bolt 120 comprising a second proximal end connected to the first blade segment 101 and a second distal end connected to the second blade segment 102, and a third bolt 120 comprising a third proximal end connected to the first blade segment 101 and a third distal end connected to the third blade segment. At least two of the first bolt 120, the second bolt 120 and the third bolt 120 differ in size, and a first distance between the first bolt 120 and the second bolt 120 is different than a second distance between the second bolt and the third bolt.
