(Asian Academy of Management and Penerbit Universiti Sains Malaysia, 2021-12-01) Sydorenko, Kateryna; Sydorenko, Oleksandr; Lozhachevska, Olena; Pashchenko, Olha; Сидоренко, Катерина Вікторівна; Сидоренко, Олександр Юрійович; Ложачевська, Олена Михайлівна; Пащенко, Ольга Вячеславівна
The article summarizes the essence of airport infrastructure, its role in the world air transport system. It is noted that airport infrastructure is a complex dynamic subsystem of global production infrastructure of the world economy and is aimed at providing competitive air transportation services. It is substantiated that the competitive production infrastructure of international airports is a key element of the economic development of countries in the world economy. In particular, reliable airport infrastructure is one of the key factors in increasing the countries capacity for real economic growth, both in the short and long term. Generalized and systematic views of scientists have led to the conclusion that today there is no single universally accepted methodology that would comprehensively explore and evaluate the competitiveness of the airport's infrasystem, and identify its strengths and weaknesses. Therefore, the purpose of the article is to develop and substantiate the methodology for assessing the level of competitiveness of the production infrastructure of international airports in the global aviation market. The proposed methodological approach makes it possible to provide a practical assessment of the competitiveness of the airport's infrasystem, taking into account the wide range of indicators, converted through a fuzzy linguistic approach. It should be noted that the main purpose of creating and implementing an evaluation system is to facilitate the successful implementation of the competitiveness management functions of the production infrastructure of international airports in the global aviation market. The developed model may be used by international aviation organizations and governments in the process of strategic planning of the air transport development.
Determination of the mechanism of forming the surface structures of IIX-15 steel at friction in the environment of aviation fuels on the basis of ethyl oleic esters of rye oil

Presented studies are related to the spheres of aviation and machine-building. Anti-wear properties of conventional jet fuel, fatty acids ethy esters bio-additives derived from camelina oil and their blends were investigated experimentally, It was found that lubricity of bio-additive is significantly higher comparing to conventional oil-derived jet fuel. It was found that addition of bio-additive into the composition of jet fuel leads to strengthening of boundary film, decreasing of friction coefficient and improvement of anti-wear properties of fuel blends.
Influence of electromagnetic treatment of fuels and oils on the formation of wear resistance of friction pairs
(National Aviation University, 2019) Trofymov, Igor; Svyryd, Mykhailo; Matveyeva, Olena; Sydorenko, Oleksandr
This article discusses the effect of electromagnetic processing of fuels and oils on the formation of wear resistance of friction pairs and presents the results of some of our research in this area. The main goal of the research was to improve the performance properties of fuels by electrophysical treatment, which occurred when they were passed through an electromagnetic field and to study the effect of the influence of a magnetic field on the change in the energy state of lubricants. In the work, a complex was used to study the tribological characteristics of fuels and lubricants, which allows you to take photographs and video images of surfaces in a dynamic mode. The presented method of treating fuels with an electromagnetic field makes it possible to acheivean improvement in their anti-wear properties, a decrease in the friction coefficient, and a more uniform and dense oxide films on the friction surfaces. The research results can be applied in the field of mechanical engineering to increase the reliability of parts of fuel systems, they can be applied by experts by tribologists, chemotmologists, as well as experts in the field of operation of fuel and lubricating systems of ground and aviation equipment. Predictive assumptions on the development of the object of study – the continuation of research on the effect of force fields on the antiwear properties of fuels and lubricants, as well as the ability to control and regulate wear parameters by electromagnetic fields.
Integration processes in airport sector
(National Aviation University, 2019-04-22) Сидоренко, Катерина Вікторівна; Сидоренко, Олександр Юрійович; Sydorenko, Kateryna; Sydorenko, Oleksandr
The integration of international airports through Global Value Chains and Global Production Networks is the result of the commercialization of airport services and the privatization of international airports, the reduction of state regulation of airlines and the liberalization of the air transport market. It should be noted that increased competition on the global aviation market contributed to a rapid structural change, the emergence of new features. Firstly, in the airport sector there is both horizontal and vertical integration; secondly, the features of services: aviation services are typical of all international airports, while land-based services and non-aeronautical services are not subject to strict regulation by the state and develop within the framework of policies and strategies of international airports.
