VETROELECTRIC POWER STATION WORKS AS FOLLOWING

At a wind speed of 5.5-6.0 m / s and setting all wind turbines 2 to the wind, the incoming airflow in the confuser 4 increases its speed and through the guiding devices 7, 8 enters the working blades of the stages 11 of the turbine 3 installed on the drum 43 , Mounted on a shaft 31, which drives a shaft 36, a reduction gear 28 and a generator 5 through a conical gear 35.

When the direction of the wind changes, each wind turbine 2, according to the height of the tower 6, which is an autonomous power source with electric power transmission from all windmills 2 to the common wind power station, is set to the wind due to the difference in the dynamic wind pressure on the side surfaces of the wind turbine 2 and the annular nozzle 10.

The large geometric dimensions of the ring 10, as compared to the wind turbine 2, provide a large difference in the forces of the dynamic wind pressure and rapid rotation of the motors 2 to the wind by moving the rollers 37 along the inner surface of the support ring 38.

The increase in the speed of the air flow by half due to the tapering confuser 4 and the guide apparatus 7 on the blades of the turbine 3 of the first stage provides an eightfold increase in the power of the windmill 2, since it is known that the amount of energy contained in the wind is proportional to the area of ​​the turbine section and the wind speed to the third power, And the operation of the jet engine of the wind turbine 2, when air enters it through the inlet 34, allows increasing the output speed from the first stage of the turbine 13 to a numerical value of approximately equal to the speed of the air flow on the blades of the first stage of the turbine 3 and to increase the total wind turbine power by 1.8-2 Times.

The multi-circuit turbojet engine works as follows: the starting motor 89 rotates the compressor 75 from which the compressed air enters the combustion chambers 17, mixes with the fuel coming from the injectors (not shown in the drawing) and ignited by the ignition device, after which the combustion is carried out in Continuous mode. Simultaneously, the compressed air from the compressor 75 is withdrawn and washed outside the combustion chamber 17, providing a normal temperature of their walls, and mixed with the combustion products flowing from the chambers 17. A mixture of air and gases with a temperature of 1800-2000 ° C flows out of the common nozzle 76 and sucks the atmospheric Air through the openings 84, 85, followed by acceleration in the nozzles 80, 81, from which the air-gas mixture at a lower speed and temperature sucks air through the next holes 82, 83, and at a lower temperature and speed, enters the turbine 77 which rotates the compressor 75.
