Abstract

A rotor system for a fluid-flow turbine comprises a hub assembly (6) which is mounted on a shaft coupled with a power- transmitting device, and a plurality of rotor blades, each of which comprises an inner blade section (8, 10, 12, 14, 16), a collar (9, 11, 13, 15, 17) and an outer blade section (50, 52, 54, 56, 58). The inner blade section (8, 10, 12, 14, 16) is rotatably supported by and extends outward from the hub assembly (6) to its respective collar (9, 11, 13, 15, 17), wherein the outer blade section (50, 52, 54, 56, 58) extends outward from a respective one of the collars (9, 11, 13, 15, 17). The inner blade section (8, 10, 12, 14, 16) and the outer blade section (50, 52, 54, 56, 58) are rotatable.
