Multiple wind turbine structure with non-rotatable support mast

摘要

A multiple wind turbine structure in the form of a fixed television mast disposes the turbines in pairs supported on bearings which enable their independent 360 deg rotation about the mast to give alignment with the wind direction. Large diameter rotors are stabilised by having blades which are braced via front and rear radial struts (9) in conjunction with a support ring (8) concentric with the axis and housing of its generator. Various sizes of rotor are proposed to enable optimal use of space and suitable materials include carbon fibre-reinforced plastics, aluminium alloy, steel, concrete, etc.
