A vertical axis wind turbine comprising a rotor having a substantially vertical rotation axis z, said rotor comprising a plurality of blades arranged to rotate about its rotation axis z in consequence of the aerodynamic drag opposed to an air flow investing said blades. The wind turbine also comprises a casing structure in which the rotor houses. The casing structure comprises a lower plate substantially orthogonal to the rotation axis z, said lower plate defined by a first plurality of vertices V1, . . . , Vr, an upper plate substantially orthogonal to the rotation axis z, said upper plate defined by a second plurality of vertices V1′, . . . , Vn′, each vertex V1′, . . . , Vn′ of the second plurality corresponding to a vertex V1, . . . , Vn of the first plurality. |
