This article describes an innovative design of a solar-wind generator for a distributed energy Hyperloop high-speed system. The knowhow of this development is to mount flexible silicon solar panels (SP) on wind turbine blades, thus optimizing the thermal efficiency of solar panels. The basic dimensions of the wind turbine blades and the maximum internal flow velocities at the blade outlet (tips) are presented. At low wind velocities, it is rational to locate solar panels on the outer end (or the tip) of a blade, rather than along the blade length.

The cooling effect can be increased by using materials with low thermal resistance for the SP and blades, or by reducing their thickness.

To increase the heat transfer coefficient, it is recommended to use the airflow turbulence on the solar panel surface. In practice, this can be achieved both by changing the operating parameters and by introducing innovative design solutions.

For better cooling of solar panels, it is recommended to use the technology of a wind flow sucked into the blade inner cavity. Changing the geometry of the outer end (tip) of the blades and the use of deflectors also give a better panel cooling parameters.

BRICS, an international association of countries with the greatest potential for economic growth is an example of a promising international alliance capable of effectively integrating economic interests and processes to provide a serious alternative to the developed countries in terms of the international trade scale and efficiency. At the same time, the existing format for discussing intentions and statements requires the targeted institutionalization of economic interactions and the creation of international economic, primarily transport and logistics, systems. These systems should be capable of using advanced transport and logistics concepts in terms of full consumer value chains to ensure effective support for international trade commodity flows based on real-time requests and existing import-export specialization of the participating countries.

The article provides statistical data characterizing the volumes of Russia’s foreign trade with key international partners in non-CIS countries including the BRICS countries. The Federal State Statistics Service of the Russian Federation provided the statistical information in the field of foreign trade and its main aspects.

The analysis of existing international commodity flows unequivocally demonstrates a possibility of increasing international trade through the creation of transnational transport and logistics systems capable of ensuring the functioning of international value chains and efficient international exchange.

This paper describes that concrete physical and mechanical properties such as density, crack resistance, durability and reliability can be improved with introducing a high-performance chemical additive based on polycarboxylate polymers modified with electrolytes based on group I metal cations of the main subgroup in D.I. Mendeleev’s table. These high mobility polymers facilitate their diffusion ability. It is recommended to use silicon hydroxide nanoparticle dispersion as an additional component as they have such unique properties as increased reactivity.

The superplasticity and reactivity of the complex chemical additive under study proved to increase cement hydration process and enhance the formation of new hydrate phases, which contributed to a greater bending tensile strength and chemical resistance of concrete. The use of this complex chemical additive increased the compressive strength by more than 41 % and the bending tensile strength by 56 %, which contributed to concrete crack resistance.

Concrete water resistance was proved to increase by 75 % and corresponded to W14 class while concrete frost resistance increased by 70 % to the value of F2500, and chemical resistance increased by 16 % to the value Kx.s. l 0.93. According to GOST 58895-2020, this advanced concrete corresponds to the concrete with increased chemical resistance.

According to the test results of physical and mechanical properties, concrete with this complex chemical additive is recommended to use in federal highway pavement construction.

This article deals with the development of secondary vocational education and training (SVET) in the context of globalization processes. International cooperation is one of the priorities in the development of the SVET system. Constant updating of the educational content and technologies is necessitated by the professional qualification requirements and international standards. A promising area of professional education internationalization could be arrangement of international competitions and professional skills championships in the WorldSkills format. Far East State Transport University (FESTU) took part in organizing the WorldSkills BRICS Championship in the “Rail transport technologies” competence in 2022 and it is described in this paper. The professional skills competitions enhance the development of professional and expert communities, professional development of scientists, engineers, and workers in Russia and globally. Such competitions can become one of the main forms of vocational education internationalization, which will enhance and improve education quality overall.

The main objective of this work is the need to develop a new technology for automated solution of railway design problems in the information and digital environment.

For this purpose, the methodology of structural system analysis, the theory of systems, and the principle of decomposition are applied. A brief analysis of the terms related to informatization and digitalization is given, and the interpretation of the concept of “information and digital environment” in relation to the tasks of railway design. The key concepts of information modeling of construction objects in the current regulatory documentation of the Russian Federation, the main qualification features and advantages of information modeling technology are given.

Based on the results of the analysis of the structure and functionality of existing computer-aided design systems of railways and highways, the sequence of procedures of the existing technology of computer-aided design of roads is determined. The concept of automated solution of railway design problems in the information and digital environment based on the use of information modeling technologies and mathematical optimization methods is proposed. The concept is represented by a functional hierarchical model of a computer-aided design system. For its development, the Data Flow Diagrams functional modeling tool was used.

The proposed concept is the basis for the development of a computer-aided design system, which will allow the implementation of a new technology for computer-aided design of railways, reduce labor costs and deadlines for the development of design solutions, improve their quality and efficiency.

Wagon turnaround remains the key performance indicator of railway transport operations characterizing the efficiency both of a wagon fleet owner and of “Russian Railways” Company (RZD). Freight logistics efficiency in the railway sector can also be assessed using this indicator. For determining the wagon turnaround time, the duration of operations at technical stations, freight handling time and the time in motion are taken into account. “Russian Railways” company and operator companies control the three components of the wagon turnaround time. The synergies of railways, intermodal types of transport, and private railways belonging to major freight owners are of particular interest. Their interaction efficiency can be calculated using the wagon turnaround formula that considers the freight idle time and the local operations factor. The local operations at the station for serving private tracks and port sidings are regulated by a number of documents that determine the procedure for supply and departure of wagons, the number of wagons in supply, the regularity of these operations, the number and series of shunting locomotives, etc. The optimal number of wagons in supply will be determined by the minimum cost of wagon movement and wagon idle time on the station tracks. The calculation of the cost function sensitivity will make it possible to determine the limits in the optimal wagon movement changes.
