A turbine structure, particularly for OWC devices, comprises a rotor (2) having an hub (3) rotatable about a central axis of rotation (X) and adapted to be operatively coupled with external means for generating electric power, a plurality of laminar elements (5, 5', 5",...) firmly associated with the hub (3) and arranged peripherally to the central axis of rotation (X) to intercept a fluid stream and produce the rotation of the hub (3) with predetermined direction, wherein each laminar element (5, 5', 5",...) comprises a flexible seal (6, 6', 6",...) having upper and lower opposite faces (7, 8; 7', 8'; 7", 8";...) adapted to alternatively engage the fluid stream to deform and transmit a driving torque (M) to the rotor (2). The seals (6, 6', 6",...) radially extend outwardly from the outer peripheral wall (9) of the hub (3) with respective opposite faces (7, 8; 7', 8'; 7", 8";...) extending, in a non-deformed condition, mainly in planes substantially coplanar with each other and to the plane of the hub (3), perpendicular to the axis of rotation (X), to define as a whole respective mutually opposite surfaces adapted to be alternately invested by the fluid stream on their whole extension. |
