Abstract

The first object of the invention is a roof mounted wind turbine comprising a horizontal-axis cross-flow rotor (1) disposed on a roof (9) parallel with the roof ridge such that, utilising deflector plates (6, 7), the turbine generates electricity from the energy of wind accelerated over the roof. The turbine according to the invention is characterised by that the rotor (1) thereof is disposed in a support frame (2), with the additional components of the apparatus being attached to the support frame (2), said additional components being a generator (3), support rods (5), deflector plates (7), and roof mounting brackets (4). A further object of the invention is an augmented twin-rotor wind turbine mounted on a vertical pole such that it generates electricity from the energy of accelerated wind. The twin-rotor wind turbine according to the invention is characterised by that it has a support frame (2), two vertical-axis cross-flow rotors (1) enclosed in the support frame (2), a middle deflector plate (11) attached to the support pole (10), two side deflector plates (15), and a drive means (13) connected to the shafts of the rotors (1) supported in bearings in the support frame (2), with the middle deflector plate (12) having a streamlined cross-sectional shape and being adapted for reducing air flow, and with the side deflector plates (15) being adapted for bounding the air flow path, where the shaft of one of the rotors (1) is in direct or indirect driving connection with a generator (3), and where the structure is arranged to be rotatable about the support pole (10) such that it can be turned in the direction of wind utilising a tail fin (12). The theoretical basis of the invention related to a roof-mounted wind turbine is that wind speed increases over the wind loaded side of a ridge roof. Wind passing over the ridge hits the rotor at nearly double the average wind speed. A twofold increase in wind speed allows eightfold increase in extractable energy, and therefore electricity may be generated in an amount that is significant for a household even utilising a smaller cross sectional area. The selected rotor type and the manner of placement of the wind turbine provide that harmful environmental effects (noise, visual impact) are minimised. The twin-rotor wind turbine is based on the operating principle that the air flow area is reduced by the side and middle deflector plates, which increases the flow speed at the rotor inlets, and the increased flow velocity will result in an increase in output power proportional to the cube of the wind speed, while the reduction of flow section area causes a power drop only in straight proportion to the section area. Since the highest circumferential speed of the rotor is always lower than the wind speed at the turbine inlet the noise generated by the rotor will not be louder than the noise of the wind.
