The wind generator includes two rotors (1,2) which are supported by arms (9,10) in a V-formation. The arms are articulated on a base (11) which is able to swivel about a vertical column (6) on rollers. One rotor (1) is located to windward and the second (2) is slightly downwind. The swivelling of the whole structure is controlled either by the use of an air brake (4) or by varying the drag of one rotor. The supporting arms (9,10) are normally held in the V-position by a tie bar (13) and a stay (14) but may be lowered for maintenance of the rotors. |
