    Analysis of the environmental properties of the components of traditional and alternative aviation gasoline
    (National Aviation University, 2019) Boichenko, Sergii; Shkilniuk, Iryna; Pavliukh, Lesia; Babikova, Kateryna; Iakovlieva, Anna; Vinetskaya, Roza
    In this article have been analyzed ecological properties of traditional and alternative aviation gasoline. We determine that with reducing of aromatic hydrocarbons in gasoline, saturated with oxygenates; it is possible to improve the composition of aviation gasoline, thereby reducing the formation of carbon monoxide and hydrocarbons during combustion. With increasing octane number, the concentration of toxic gases in the exhaust decreases, that improves the ecological properties. Using biofuels leads to improve environmental characteristics.

    Development of alternative jet fuels modified with camelina oil bio-additives
    (National Aviation University, 2019) Iakovlieva, Anna; Boichenko, Sergii; Lejda, Kazimierz; Kuszewski, Hubert; Vovk, Oksana
    This paper is devoted to the development and study of physical-chemical and exploitation properties of new alternative jet fuels modified with camelina oil bio-additives. The current condition of environment is analyzed as well as the impact of aviation industry on the environment. During the study the following physical-chemical properties were investigated: density, viscosity, fractional composition, heat of combustion, lubricity, corrosiveness and freezing point. It was found that properties of bio-additives are significantly different from properties of jet fuels. As a result of the work, the complex comparative characteristic of physical-chemical and exploitation properties and quality parameters of jet fuel, camelina oil bio-additive and blended jet fuel samples, was developed.

    Evaluation of jet engine operation parameters using conventional and alternative jet fuels
    (2019) Yakovlieva, Anna; Boichenko, Sergii; Lejda, Kazimierz
    Jet engine operation parameters using conventional and alternative jet fuels, obtained by blending with plant oil bio-additives, during bench tests were evaluated. Jet fuels were tested and compared in conditions of engine operation. It was determined that using alternative jet fuels improves jet engine thrust characteristics and reduces fuel flow. These provide more energy efficient operation of jet engine. Using alternative jet fuels results in reduction of gas temperature in the jet pipe. This contributes to durability of materials and structure of the engine against high temperature, as well as reducing of NOx emissions. The results of the study show that operational parameters of the jet engine powered with new alternative jet fuels completely satisfy exploitation norms set in specification for tested engine. Alternative jet fuels, proposed in the study, may be used as a working body of the jet engine without a need of making changes in its design.

    Identification and assessment of biological risk of aviation fuel supply
    (National Aviation University, 2019) Shkilniuk, Iryna; Boichenko, Sergii; Kondratiuk, Tetiana; Shevchuk, Nataliia
    The work is focused on microbial contamination of refined petroleum products and fuel systems of vehicles and means of operation and storage. A limited amount of oil resources, the introduction of ICAO and IATA standards, satisfaction of safety and operational safety requirements, economic indicators, financial profitability, require the risk-based approach in aviation fuel supply. The risks and consequences of aviation fuels microbiological contamination, impact of it on fuel quality and chemmotological reliability of the aviation engineering, have been identified, evaluated and systematized during research.

    Influence of antioxidants and antiwear additives on jet fuel properties
    (National Aviation University, 2019) Boichenko, Sergii; Golych, Yuri; Iakovlieva, Anna; Shkilniuk, Іryna; Topilnytskyi, Petro; Romanchuk, Victoriia; Babatunde, Olufemi
    The article is devoted to the study of antioxidants and antiwear additives influence on reactive fuels. The antioxidants Agidol-1, AO-80 and antiwear Hitec-580 were added to the hydrotreated fuel fraction for air-jet engines in the concentrations recommended by the manufacturer. It was established that the addition of these additives, both individually and in combination, improves the physical and chemical properties of commercial fuel for fuel-jet engines, does not affect it, and its properties meet the requirements of normative documents.

    Selected aspects of providing the chemmotological reliability of the engineering
    (2019-05) Boichenko, Sergii; Aksionov, Olexander; Topilnytskyi, Petro; Pushak, Andrii; Lejda, Kazimierz
    Transport sector is an important component of the economy that have an impact on the development and prosperity of the population. Rational use of fuels and lubricants, energy efficiency, environmental safety are included into the list of the most important problems of the modern world. Solving these problems determines in a great manner the sustainable development of the world economy and keeping comfort conditions for human being. Efficiency, reliability of operation of vehicles, rational use of operational materials depend on their correct selection. According to its quality operational materials must conform to both the model and operating conditions of vehicles. The use of poor quality materials leads to a decrease in the durability and reliability of machinery and machine parts; the use of materials of higher quality than required causes unreasonable increase in costs. The knowledge of machinery suggest not only the knowledge of construction, kinematic, dynamic, and temperature characteristics but also physico-chemical properties of constituent materials that are necessary for analyzing and forecasting of physico-chemical processes during use of a Fuels or a Lubricants. Thus, the efficiency and reliability of vehicles operation depends not only on their structural characteristics, but also on the optimal selection of Fuels and Lubricants, Technical Liquids and other Operational Materials. Work professional activity of specialists dedicated to petroleum refinery, organizing of storage, transportation and distribution of products, assurance of correspondence between the properties of Fuels, Lubricants, Technical liquids and the conditions of operation of technology and engines aimed at obtaining maximum technical, economical, ecological and social effects is called usage of Fuels, Lubricants and Technical liquids. To know Fuels, Lubricants and Technical liquids is to clearly understand the interconnection of quality parameters with physico-chemical and energy processes, occurring in the process of their use under specific conditions, and also the connection with their chemical and group composition. The knowledge of technology suggest not only the knowledge of construction, kinematic, dynamic, and temperature characteristics but also physico-chemical properties of constituent materials that are necessary for analyzing and forecasting of physico-chemical processes during use of a Fuel or a Lubricant. The study of the essence, regularity (tendens) and connections of phenomena and the processes of use of Fuels, Lubricants, Technical liquids in Aviation Technology with the help of special methodological tools is the base of Aviation Chemmotology. Aviation Chemmotology is a part of Chemmotology that studies and solves the problems of ensuring the necessary quality and application requirements of Fuels and Lubricants used in Aviation Technology. Chemmotological reliability is a reliability of technology depending on the Quality of Fuels and Lubricants (the ability of technology to maintain good reliability when operated with Fuels and Lubricants grades that are of a economically reasonable quality level). This monograph as an intergative scientific work of many scholars is a striking example of the representation of these aspects and really illustrates the modern consolidated work of scientists and practitioners, trends in the development of scientific schools of different universities, different countries and science in general. Because, as is know, science does not have borders. Scientific achievements are global civilizational heritage.
