The article discusses the development and evaluation of the design of a rotary-type mechanized parking system, the use of which will solve the problem of shortage of parking spaces in large cities. The paper presents the results of the research, a patent analysis was carried out, the composition of the mechanized parking system was determined and a rotor-type design was developed, an engineering analysis of the design was performed using the Autodesk Inventor software system. The calculation showed that the structure meets the requirements for strength characteristics.

There are two main problems that slow down the wind industry - these are large losses in the kinematic characteristics of the wind flow during its use and small gusts of wind in non-northern regions of the Russian Federation. The designed confuser-diffuser system is able to solve these problems by increasing the KIEV (Wind Energy Utilization Factor). In the article, the previously designed systems for incrementing the kinematic parameters of the wind, which are installed on the developed wind turbine with a vertical axis of rotation "Object 1-U", were analyzed.
