A wind turbine comprises a vertical driven shaft 9 supporting curved blades 2 via a central drum 7 having apertures. The blade trailing faces are corrugated 5, improving performance and the leading faces are cambered 4. Radially outside the blades lie adjustable inlet guide vanes 12 and outside that a building supporting the turbine assembly forms large wind collecting vanes 11, divide the building periphery into segments and forming convex sided ducting. Incoming airflow enters the segments on the side of the building facing the wind and is controlled by slats 14 pivotally mounted on the large vanes and by the guide vanes and fed to turn the blades. Excess airflow passes through the central drum ensuring all of the blades are active. The building forms part of the turbine, may be multi-storey and also houses accommodation e.g. offices, factories or a sports, civic and conference centre. |
