Abstract
A turbine structure, includes a rotor having a hub rotatable about a central axis of rotation and adapted to be operatively coupled to an external system generating electric power, a plurality of laminar elements firmly associated with the hub and arranged peripherally of the central axis of rotation to intercept a fluid stream, wherein each laminar element includes a flexible seal having upper and lower opposite faces adapted to alternatively engage the fluid stream to deform and transmit a driving torque to the rotor. The seals radially extend outwardly from the outer peripheral wall of the hub with respective opposite faces extending, in a non-deformed condition, mainly in planes substantially coplanar with each other and to the plane of the hub, perpendicular to the axis of rotation, to define as a whole respective mutually opposite surfaces adapted to be alternately invested by the fluid stream on their entire extension.
