The invention relates to a flow-based power generating plant with a turbine that can be subjected to a fluid flow and comprises a number of blades that extend from a blade root to a blade tip and are attached by the blade root to a rotating rotor, wherein, under the effect of the fluid flow, the blades can be elastically twisted about an axis (P) running through the blade root in such a way that the pitch of the blades can be increased, wherein the blade root is fastened to the rotor with a bearing device interposed and the bearing device is formed with respect to the axis rigidly in terms of tension, compression, bending and shearing but yieldingly in terms of torsion, wherein the bearing device has a primary connection part fastened to the rotor and a secondary connection part fastened to the blade root, which parts are connected to one another via a multiplicity of leaf springs in such a way that the primary connection part can be turned in relation to the secondary connection part under elastic deformation of the leaf springs, and the leaf springs are arranged on a substantially circularly formed circumference and have a rectangular cross section with a longer side and a shorter side, the longer side running radially outwards with respect to the circumference on which the leaf springs are arranged. |
