Abstract: A jointed rotor blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of blade segments has at least one shell member defining an airfoil surface and an internal support structure. The internal support structure of the first blade segment includes a beam structure extending lengthwise that structurally connects with the internal support structure of the second blade segment via a receiving section. The rotor blade further includes one or more pin joints positioned on at least one of internal support structures of the first blade segment or the second blade segment. Thus, at least one of internal support structures of the first blade segment or the second blade segment includes varying material combinations along a span of the rotor blade at locations of the one or more pin joints so as to reinforce the one or more pin joints.

Abstract: A jointed wind turbine rotor blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. A beam structure extends span-wise from the first blade segment into a receiving section formed in the second blade segment. The receiving section includes opposite spar caps and opposite interconnecting webs. The spar caps have a constant thickness along the receiving section where the spar caps overlap with the beam structure and are formed of a material or combination of materials along the receiving section to produce a desired stiffness of the spar caps along the receiving section. The webs have a reduced amount of conductive material adjacent to a chord-wise joint between the blade segments.
