Abstract
A rotor blade for a wind turbine includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of the first and second blade segments includes at least one shell member defining an airfoil surface and an internal support structure. The first blade segment includes a beam structure extending lengthwise that structurally connects with the second blade segment via a receiving section. The rotor blade also includes at least one chord-wise extending pin positioned through the chord-wise joint so as to secure the first and second blade segments together. Further, the chord-wise extending pin includes a hollow cross-section that extends from a trailing edge end to a leading edge end thereof.
