ANNOTATION 
As global demand for wind power grows, the total installed capacity of wind 
turbines as of 2018 has reached 595 GW . Small wind turbines are installed closer 
to urban areas than large wind turbines, which improves opportunities for 
Autonomous urban equipment. For large wind turbines, a horizontal-axial load-
bearing configuration with three blades is considered standard and has maximum 
aerodynamic efficiency. In the case of small wind turbines, they can be distinguished 
by their lift or drag configuration, depending on the effective aerodynamic force that 
rotates the wind turbine rotor. Figure 2.7 shows that vertical wind turbines are 
significantly more efficient than their counterparts with a horizontal axis. Around 
the world, the largest factor in increasing CO2 concentrations is the burning of 
extracted fuels and logging. It is important to develop efficient renewable 
technologies to ensure energy supply while reducing carbon emissions. Among the 
renewable sources of wind energy is a very sustainable technology with great 
opportunities for commercialization. With great potential and growing energy 
challenges, this small but important technology can be of great help to households 
in Kazakhstan's society. This study presented a theoretical method for developing a 
small-sized Archimedes wind turbine based on the law of conservation of angular 
momentum, and the efficiency of the developed Archimedes wind engine was 
evaluated using the CFD method. Frequency dosimetry was used to study the 
aerodynamic characteristics of the Archimedean spiral wind turbine blades, test the 
CFD method as a means of designing an Archimedean wind turbine, and understand 
fluid dynamics in the near Wake. The Archimedes spiral wind turbine, which is a 
new concept, was developed using the principles of the Archimedes spiral. Unlike 
traditional hawks, which use lift to generate power from wind power, the 
Archimedes ' spiral wind turbine uses both lift and drag. Archimedes spiral wind 
turbine can use kinetic energy from wind power
