A horizontal-axis wind turbine is described, the wind turbine of a rotor- support de-sign, wherein the structural load of the wind turbine rotor is carried by the wind tur-bine tower itself. The turbine uses a composite shaft to transfer torque from the wind turbine rotor to the generator, the shaft having high torsional strength but being flexi-ble in bending. This prevents the transmission of bending moments from the rotor hub to the generator system. Accordingly, the components of the turbine can be rigidly mounted to the turbine main frame, removing the need for vibration damping ele-ments. The result is a wind turbine of reduced weight, which can be modelled and de-signed for improved efficiency and performance. Furthermore, as the turbine compo-nents do not have to be load-balanced, the turbine can be of a modular construction for relatively easy servicing and/or upgrading.
