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. |

1. A turbine structure, particularly for OWC devices, comprising:
a rotor (2) having a hub (3) rotatable about a central axis of rotation (X) and configured to be operatively coupled to an external system generating electric power; a plurality of laminar elements (5, 5′, 5″, . . . ) firmly associated with fixedly coupled to said hub (3) and arranged peripherally of said central axis of rotation (X) for intercepting a fluid stream and producing the rotation of said hub (3) in a predetermined direction; wherein each of said laminar elements (5, 5′, 5″, . . . ) comprises a flexible seal (6, 6′, 6″, . . . ) having both the reciprocally opposite faces (7, 8; 7′, 8′; 7″, 8″; . . . ) adapted to alternatively engage the fluid stream to deform and transmit a driving torque (M) to said rotor (2), wherein said seals (6, 6′, 6″, . . . ) radially extend outwardly from an outer peripheral wall (9) of said hub (3) with said opposite faces (7, 8; 7′, 8′; 7″, 8″; . . . ) extending, in a non-deformed condition, mainly in planes substantially coplanar with each other, parallel to a rotation plane of said hub (3) and perpendicular to said axis of rotation (X) to define as a whole opposite surfaces adapted to be alternately invested by the fluid stream on their entire extension, and wherein each of said laminar elements (5, 5′, 5″, . . . ) has a corresponding sail (6) provided with one or more openings (15) configured to allow a partial passage of the fluid stream through the face (7, 8; 7′, 8′; 7″, 8″; . . . ) invested thereby. |
