Definitions
- the present invention concerns a device for the conveyance of aeriform masses onto internal eolian rotors, for increasing the energetic output thereof .
- the aim set forth is reached by means of the device according to the present invention, consisting of a f ixed structure , i . e . not rotating under the action of the wind, consisting of modules that can be assembled around the axis of the eolian rotor , each one consisting of a plurality of diaphragms radially placed so as to lead all the aerif orm mas s , corresponding to the steradian determined by the external entrance surface , onto the blades of the central rotor along an inclined direction in the rotation direction of the turbine , without incidence onto the negative part .
- Figure 1 shows a plant scheme of a device for the conveyance of aeriform masses onto internal eolian rotors.
- Figure 2 shows an axonometric view of a device with two superimposed layers of radial diaphragms.
- Figure 3 shows a variant with a plurality of layers, develloped in height.
- the enclosed figures show a device for the conveyance of great aeriform masses onto rotors' blades placed inside said device, comprising:
- said diaphragms 1 may be realized, as above described, as flat and fixed, but also in possible variants with a curved structure for facilitating the sliding of the aeriform molecules towards the rotor, and with angles adjustable according to the intensity and the quality of the wind.
- a possible extension of the diapragms' surface is provided with the manual or automatic projection of the end parts for increasing the aeriform mass conveyed.
