Abstract: A wind turbine rotor blade joint assembly and method of manufacturing same is disclosed. The rotor blade includes an upper shell member having a spar cap configured on an internal face thereof and a lower shell member having a spar cap configured on an internal face thereof. A shear web extends between the spar caps along a longitudinal length of the blade. The shear web includes first and second longitudinally aligned components that extend from and are integral with respective spar caps. A joint assembly is configured between facing transverse ends of the first and second components of the shear web. The joint assembly includes a connecting structure configured to receive the transverse ends of the first and second components. The connecting structure is infused and integral with the first component of the shear web and bonded with the second component of the shear web.

Abstract: The present subject matter is directed to a rotor blade assembly having a rotor blade with a blade tip segment having a blade tip and a blade root segment having a blade root. The blade segments extend in opposite directions from a chord-wise joint. The blade tip segment includes a beam structure extending lengthways that structurally connects with the blade root segment via a receiving section. The assembly also includes a plurality of first bolt joints located at a first end of the beam structure for connecting with the receiving section of the blade root segment. The assembly also includes a lightning protection system with at least one lightning receptor coupled to a lightning receptor cable. The lightning receptor cable is routed from the blade tip to each of the plurality of first bolt joints and to the blade root.
