Aero-elastically tailored wind blade tip joint

A wind turbine blade, comprising:

• a first blade segment having a pressure side shell member, a suction side shell member, an internal support structure and a beam structure extending in a span-wise direction;
• a second blade segment having a pressure side shell member, a suction side shell member, and an internal support structure, the first blade segment and the second blade segment extending in opposite directions from a chord-wise joint;
• wherein the first blade segment is structurally connected via the beam structure to the second blade segment, to form a joint assembly, the joint assembly comprising;
• a joint rod located at a first end of the beam structure for connecting with a receiving section of the second blade segment to form a coupling joint about a joint axis,
• wherein the coupling joint is coupled to an adjustable elastic support, to provide at least one of movement and flexing of the coupling joint in a y-direction, such that a bending motion of the beam structure automatically induces a twist motion.

A method of assembling a wind turbine blade, the method comprising:

• arranging a first blade segment and a second blade segment in opposite directions from a chord-wise joint, each of the blade segments having a pressure side shell member, a suction side shell member, and an internal support structure;
• inserting a beam structure extending lengthways from the first blade segment into a receiving section of the second blade segment;
• and
• attaching a free end of the beam structure with the receiving section of the second blade segment using a coupling joint and a bearing component,
• wherein the coupling joint is coupled to an elastic support, to provide movement/flexing of the coupling joint in a y-direction, and a torque coupling positioned offset from a coupling joint axis, such that a bending motion of the beam structure automatically induces a twist motion.
