Accordingly, it is important to take into account previous developments in the various aviation engineering fields relevant to new aviation vehicles on the SC. Thanks to a detailed analysis of the flight and performance characteristics of widely known aircraft models on the SC from the 70s of the 20th century to the present, a picture of the distribution of aerodynamic schemes and important design parameters with conclusions regarding their choice is obtained. For aircraft on SC, the corresponding boundaries of their work in height and speed are determined in comparison with long-range aircraft. Also, acceptable values of unit load per unit area and specific power have been obtained that allow aircraft to be lifted on the SC at altitudes of at least 20 ths.m. These altitudes are promising for longhaul aircraft to be operated on to SC for the purpose of performing the functions of an "aerodynamic satellite" or the so-called "pseudosatellite". The design parameters of the "pseudosatellite" demonstrator on the SC with a wingspan of 11m and a starting mass of 16 kg were obtained.Item Analysis of nature protecting activity of the Ukrainian airports(National Aviation University, 2020-06-17) Mushta, Maryna AndriivnaObject of research – the formation of environment pollution due to airports activities.

These problems are characteristic of almost the entire range of brands of modern rocket fuels suitable for application. These are problems with the basic physic-chemical and operational properties, technical requirements for the quality of rocket fuel, problems with the functioning of the refueling infrastructure, as well as ensuring the purity of rocket fuels. Given the ban on the use of highly toxic poisonous rocket fuels based on nitric acid, there is a problem of replacing them with less toxic. This problem is aggravated by the lack of production of their own petroleum-based hydrocarbon rocket fuels in many countries. In general, it leads to acute problems with the supplying spacecraft and rocket carriers with rocket fuels. In particular, such a problem arises in Ukraine with Ukrainian-made missiles. The constant attention to the problem of the aviation and rocket fuels quality results from many factors. The research has used a comprehensive approach to fuel quality assessment, analysis of world experience, synthesis of results and retrospectives, historical-evolutionary and logical approach. High level of fuels purity provides high reliability, safety of flights, increases technical resource of engine units. Therefore, expenses for achievement and maintenance of necessary level of purity of fuel and working liquids are quite justified. The result of the research is a classification of liquid rocket fuels based on their component composition and chemical structure. Requirements to energy, kinetic, operational characteristics, ecological and economic properties of liquid rocket fuels (LRF) are formulated. Given the unsatisfactory environmental conditions, the use of kerosene as a rocket fuel is more relevant compared to heptyl rocket fuel. Jet fuels T-1, T-6, T-8B are well suited for space technology of many countries, but very few countries can produce them. Purchasing in neighboring countries is not always possible for a number of reasons. Comparative analysis shows that liquid rocket fuel RP-1 in most respects is an analogue of jet fuel T-1 and T-6 and can be used as a substitute for rocket carriers. However, the problem of development of standards and regulations on quality control of LRF during their storage and operation is not solved. In particular, there is no clear regulation for the process of refueling LRF missiles at low temperatures. There are no regulations on the content of free and dissolved water and mechanical impurities in the LRF, unlike aviation fuels. One of the promising types of rocket fuels are hydrogen fuel cells. The results of the research can be applied in the field of spacecraft operation, as well as refueling infrastructure and cleanliness of rocket fuels. The research results can also be used by chemical experts, specialists in the field of operation of refueling and storage of LRF.Item Analysis of some aspects of microorganisms application for inorganic materials treatment(Національний авіаційний університет, 2014-07-20) Карпенко, Валерій Іванович; Лазарєв, Віктор Георгійович; Дражнікова, Анна ВікторівнаThe article discusses the possibility of integrating multiple methods of biotechnology, namely the elimination of oil pollution using biodegradation, biosorption of heavy metals, obtaining of microbial nanoparticles, technology of microbial fuel cells and others.

Aviation safety is one of the prioritized directions in the industry. Its managerial decision-making process is primarily based on a versatile analysis of security data in which the choice of the appropriate mathematical apparatus is fundamental. This article suggests applying fractal-statistical analysis to evaluate the aviation safety management system in terms of determining the random distribution of quantitative dynamics of aircraft crashes with lethal consequences in the period from 1946 to 2017. This allows us to verify the adequacy of probabilistic approaches appliance in analysing the dynamics of aviation disasters. The results of research carried out on the basis of the Hurst exponent have allowed us to conclude that the dynamics of aviation disasters is characterized by the effect of "spatial memory". In other words, these are "hidden laws", for which further investigation can become an effective tool for the development of proactive methods in managing aviation safety.Item 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, RozaIn this article have been analyzed ecological properties of traditional and alternative aviation gasoline.

Anti-wear properties were estimated on a four-ball tester by the value of the scuffing load, friction torque, friction coefficient and the scuffing load applied to the friction pair operating in a tested fuel sample. The state of friction pairs’ surfaces was studied using the system for tribological characteristics of fuels and lubricants investigation by comparing microphotographs of friction pairs’ surfaces. It was determined that lubricity of bio-additives is intensively higher comparing to conventional jet fuel. Bio-additives derived from camelina oil provide formation of better oxidative film on friction pairs’ surface with higher elasticity. It is stipulated by the chemical composition of fatty acids ethyl esters: high polarity of molecules stipulate its’ good adsorption at the surface of friction pair. Adding bio-additives into jet fuel provides strengthening of boundary film and thus improves anti-wear properties of fuel blends.Item Antibiotic resistance of Escherichia coli isolated from Ukrainian Betula verrucosa Ehrh. pollen after microbiological analysis(Slovak Agricultural University in Nitra, 2013-08-01) Shevtsova, Tetiana; Hleba, Lukáš; Kačániová, Miroslava; Brindza, Ján; Garkava, Kateryna; Гаркава, Катерина ГригорівнаSeven samples of silver birch pollen from different habitat of Ukraine were investigated in order to estimate their contamination with the Enterobacteriaceae family, anaerobic bacteria and fungi.
