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 line. Each of the first and second blade segments includes opposite spar caps. The first and second blade segments are connected at the chord-wise joint line by internal joint structure, wherein the joint structure is bonded to the opposite spar caps in at least the second blade segment. The spar caps in the second blade segment have a first section with a first chord-wise width that is unbonded to the joint structure and a second section with a second chord-wise width that is bonded to the joint structure. The second chord-wise width is greater than the first chord-wise width.

Abstract: A rotor blade for a wind turbine including first and second blade segments extending in opposite directions from a chord-wise joint. The first and second blade segments include one or more shell members and internal support structures coupled to an inner surface of the one or more shell members of the first and second blade segments. The internal support structure of the first blade segment includes a beam structure extending between a first end at the chord-wise joint and a second end such that the beam structure is received by a receiving section of the internal support structure of the second blade segment. The rotor blade includes one or more spacer materials arranged within the first blade segment between an exterior surface of the beam structure and the inner surface of the one or more shell members to reduce a bond gap therebetween.
