Hybrid tubular lattice tower assembly for a wind turbine

摘要

The present disclosure is directed to a tower assembly for a wind turbine. The tower assembly includes a lattice tower portion, a tubular tower portion, and a transition region therebetween. The lattice tower portion includes a plurality of structural members connected together to define an open lattice tower. Further, the structural members include a plurality of supports and a plurality of cross-support members. The cross-support members are connected between the supports so as to define one or more openings. The tubular tower portion includes a lower portion and an upper portion. The first transition region includes a single-piece connection structure, a plurality of arm members, and a plurality of node connectors. The connection structure has a circumferential body configured to receive the lower portion of the tubular tower portion therein. Further, the node connectors join the plurality of supports of the lattice tower portion to the connection structure via the plurality of arm members.
