A turbine rotor 100 for a wind or water turbine comprises a hub 20 with a plurality of stubs 22 for connection to a respective blade 21. Each blade 21 has a pair of spaced apart annular bearings 41, 42 located within a root end 23 of the blade. Each stub 22 protrudes into and is rotatably received within a respective spaced apart bearing 41,42 and the blades are supported on the hub. The bearings 41,42 may be supported by bulkheads 31,32 and may spaced by at least 1.5m. The rotor diameter may be at least 45m. The stubs 22 may be detachable from the hub core (19, fig.7B). The stub (22", fig.7C) may comprise male and female parts (50,51). |
