Abstract (en)

[origin: WO2019219139A1] A wind turbine rotor blade includes a first blade section and a second blade section which engage each other across a joint interface. A connection joint couples the first and second blade sections together across the joint interface. The connection joint includes a plurality of eyes provided at the first and second blade sections and a clamp assembly coupled to the eyes across the joint interface. The clamp assembly includes a plurality of clamp supports, at least one retention head on each side of the joint interface, and a plurality of fasteners. Each of the retention heads is formed from a plurality of discrete bridge elements arranged to collectively form the retention head. The modular nature of the retention heads accommodates various misalignments in the elements of the connection joint. A method of assembling a wind turbine blade is also disclosed.
