A modular rotor blade for a wind turbine, comprising at least a first module and a second module, wherein the first and second modules are adapted to be rigidly fixed to each other by a connection arrangement, the connection arrangement comprising a connector rod bonded to at least one receptacle adapted to receive the connector rod, the connector rod and the at least one receptacle forming a sealing flange, wherein the connector rod and the at least one receptacle have rectangular cross sections, and wherein a permanent bonding joint defined between the first and second modules comprises a substantially uniform bond line inducing a substantially uniform load distribution between the connector rod and the at least one receptacle.
A modular rotor blade for a wind turbine, comprising at least a first module and a second module, wherein the first and second modules are adapted to be rigidly fixed to each other by a connection arrangement, the connection arrangement comprising a connector rod bonded to at least one receptacle adapted to receive the connector rod, the connector rod and the at least one receptacle forming a sealing flange, wherein the connector rod and the at least one receptacle have an elliptical cross section, and wherein a permanent bonding joint defined between the first and second modules comprises a substantially uniform bond line inducing a substantially uniform load distribution between the connector rod and the at least one receptacle.
A method for assembling a sectional wind turbine blade, said method comprising:
- providing a sectional wind turbine rotor blade having a first blade section and a second blade section;
- fitting together the first and second blade sections with a connector;
- forming a permanent joint between the first and second blade sections by:
- sealing the connector;
- and
- forming a permanent, substantially uniform bonding joint between a connector rod and at least one receptacle inducing a substantially uniform load distribution between the connector rod and the at least one receptacle, the connector rod and the at least one receptacle forming a sealing flange.
