- the wind turbine operates with lower wind speeds and with high revolutions.
- Shovel Wind Turbine with Conical Fairing kinematically connected with an electric generator that produces electrical energy for consumers.
- a wind turbine is usually installed at a height of 10 m or more from the ground. The higher the wind turbine is installed from the ground, the more likely it is to get the necessary wind flow.
- the objective of the present invention is to provide a method and installation for generating electrical energy, operating continuously and regardless of the speed of the natural wind flow. Such an installation should work with high efficiency and low noise using solar, kinetic and potential energy.
- a method for producing electric energy including the creation of an artificial air flow of the required speed, the presence of a solar battery and a group of solar concentrators, the transmission of electric current from the solar batteries and groups of concentrators on an electric motor by means of which a gearbox is rotated, a gearbox connection with a movable support on which a frame rotating at a given speed and a vortex air turbine are mounted.

- turbines when they rotate, they can use the kinetic and potential energy of artificial air flow and the electrical energy of solar panels.
- Another embodiment of the present invention describes a bladeless installation for generating electrical energy, including a generator, a rotor associated with the generator, a device for compressing and holding the air flow, equipped with a group of guide holes twisting the air flow in the direction of rotation of the rotor, means for transmitting energy and a group of solar panels.
- the rotor can be made disk-shaped, and a group of holes can be located in its peripheral part and at an angle to the surface of the rotor disk, and the holes can be provided with a concave working surface to create a reactive effect.
- the specified group of holes can be made cylindrical, conical or in the form of nozzles.
- the installation may further include a partition installed in front of the rotor and equipped with a group of guide holes made with the possibility of directing the incoming air flow to the rotor at an angle with its preliminary twisting in the direction of rotation of the rotor.

- the rotor and the baffle can be made with the possibility of eliminating the disruption of the incident air flow at speeds less than 60 m / s.
- Figure 1 presents a diagram of a bladeless turbine.
- Figure 2 presents the installation diagram with bladeless turbines, solar panels and solar concentrators - mirrors.
- Fig. 3 shows a bladeless wind farm operating on a natural air stream.
- the installation is equipped with conical and annular fairings, a partition with guide holes and a rotor with inclined holes.
- conical and annular fairings As devices for compressing and holding the flow, it is possible to use a cone and a koludovy fairing.
- the rotor is kinematically connected to the generator.
- the unit is mounted on a rotating frame. The frame drive operates during the day from solar panels or a group of solar panels, and at night from its own electricity.
- the implementation of the method and installation for energy production occurs with a rotation radius of at least two meters with a tangential (angular) velocity of more than 12 m / s.
- two or more two wind power modules are installed on a rotating frame, having a rotation radius of at least 2 m. At night, half of the generated electrical energy goes to consumers, and the second part goes to rotate the frame.
- a wind farm is launched from an external current source, solar panels, mechanically, or a mobile power station.
- one frame is installed with energy modules on top of another vertically.
- the required number of vertical energy modules is recruited to increase power.
- the number of modules can be arbitrary (1, 2, 3, 4, 5, 6, etc.). However, it is preferable to use one module, more preferably two or another even number of modules (4, 6, 8, etc.).
- the occupied area of a vertical wind farm is several times smaller than that of similar wind power plants located horizontally.
- the frame of the wind farm should be made of a pipe that has as little resistance to the flow of incoming air.
- the frequency of rotation of the frame depends on the required speed of the incoming flow.
- the speed of the incoming air flow is usually equal to the angular (tangential) speed of a point located at a certain radius of rotation. For example, a free-stream velocity of more than 10 m / s is needed. We take a radius of rotation of 5 meters. Then at 30 rpm of this frame, the speed of the incoming air flow, at the extreme point, will be equal to 15 m / s. At this airflow rate, even traditional wind farms can operate at full capacity.
- a vortex bezelless turbine in which the openings are similar to small blades, will work better than a traditional wind farm, since its speed is twice as high and the losses are much lower.
- the holes in the rotor can be made cylindrical at the required angle to the plane of the disk - the rotor, they can also be conical or in the form of nozzles, which can help accelerate the rotation of the rotor and create swirl flow.
- the proposed solar wind farm operates in the established optimal mode (i.e., in the mode it generates the necessary amount of energy sufficient to support the work of itself and consumers)
- the power can be transferred from the rotor to the generator without an accelerating multi-stage gearbox (multiplier).
- multiplier multi-stage gearbox
- a speed reducer will be needed.
- a group of mechanical elements of a conventional wind turbine is not required in the new method and device. This increases reliability, reduces maintenance and extends the life of the proposed installation.
- the proposed method and installation for energy production may operate continuously throughout the year, with an annual efficiency of 95% - 98%, and not 20% - 25%, as with traditional wind farms, which depend on the natural wind flow.
- the additional use of solar panels allows you to give even more energy to consumers.
- the noise characteristics of the proposed wind farms are lower than conventional ones, they do not have the formation of infrasound. Therefore, the proposed solar wind farms can be located near the facility using the generated energy, which will reduce the cost of power lines.
- bladeless turbines affects the method of rotation of the rotor itself.
- the rotor rotates due to the formation of a reactive effect (also used in rocket and aircraft construction) and air pressure on the surface of the holes.
- torque is generated simultaneously on all working surfaces of the holes of the turbine rotor, which increases the characteristics of the turbine.
- the working surfaces of the turbine rotor are the surface of the rotor holes.
- the overall dimensions of the proposed vortex bladeless turbine are 3-4 times smaller than that of traditional wind farms, and, consequently, its weight is much less at the same power.
- Testing of a vortex turbine with guide holes showed that at the same power, its air flow is several times lower than that of a conventional turbine with blades, where the lifting force works, like the wing of an airplane.
- Modern installations for converting wind energy into electricity have reached, in part, the limits of their efficiency.
- the proposed method and installation can significantly increase the efficiency of the process of converting air energy due to the free flow at speeds from 15 m / s to 60 m / s. In this speed range, conventional wind farms do not work or work poorly.
- Electricity production by the proposed method and the solar wind farm does not depend on gusts of natural wind, therefore it is uniform and adjustable, which is very important for consumers.
- the installation is mounted under a canopy with solar panels mounted on it. Therefore, it is not affected by precipitation, which increases its service life.
- the roof or canopy above the installation is mounted from inexpensive but durable materials.
- a protective net is installed in the lower part of the roof, which prevents birds or animals from entering the working area.
- Twisting the flow in front of the rotor accelerates the movement of air molecules, which is not achieved in conventional wind farms. It is known that when twisting air flow, air consumption increases, and, consequently, increases, and the kinetic energy of the molecules, which means the power of the turbine increases.
