A turbine rotor for a wind or hydropower plant or for propulsive means for a vessel where the turbine rotor comprises a generally doughnut-shaped hub. The doughnut-shaped hub is configured as a closed, hollow profile in a cross section B, and wherein the doughnut-shaped hub is formed either in the shape of a torus, the torus being circularly shaped in cross section B and the torus being ring-shaped in cross section A wherein the outer and inner circumferences of the ring are circular, or in the shape of a quasi-torus, the quasi-torus being polygonally or circularly shaped in cross section B and the torus being ring-shaped in cross section A wherein the outer and inner circumferences of the ring are polygonally or circularly shaped, on which torus or quasi-torus at least one rotor blade is provided. There is also provided a wind, hydro or tidal plant comprising the turbine rotor. |
