Overview of the 18th International Scientific and Technical Conference Rapid Solidification Materials and Coatings A A Lozovan1 and D K Kostrin2 1Department of Materials and Materials Technology, Moscow Aviation Institute (National Research University) “MAI”, 121552, Orshanskaya, 3, Moscow, Russia 2Department of Electronic Instruments and Devices, Saint Petersburg Electrotechnical University “LETI”, 197376, Professora Popova, 5, Saint Petersburg, Russia E-mail: [email protected] Abstract. In this preface the main results of the 18th International Scientific and Technical Conference Rapid Solidification Materials and Coatings that was held on 19–20 October 2021 in Moscow, Russia are discussed. From 19 to 20 October 2021, the 18th International Scientific and Technical Conference Rapid Solidification Materials and Coatings (RSMC–2021) was held at the Moscow Aviation Institute (National Research University). Despite the difficulties associated with the coronavirus pandemic, more than 100 specialists from leading universities, the Russian Academy of Sciences and Russian enterprises, as well as scientists from Ukraine and Belarus, took part in the Conference. For the successful holding of the Conference in a pandemic, all the necessary measures were taken to ensure the implementation of sanitary rules and standards for the protection of Conference participants. At the Conference the results, which were obtained in the last year after the previous Conference, of the theoretical and experimental studies on the physics of condensed matter, low-temperature plasma physics, electronic and ion-plasma surface modification, physical methods of film deposition and other studies obtained over the last year after the previous Conference. The main objects of these studies were superficiality and superficial phenomena. Therefore, to the development and improvement of methods of surface modification and coatings deposition, as well as methods of their research and development of modern surface treatment equipment was paid the greatest attention at the Conference. During the Conference more than 70 reports were presented, which were heard in the following, traditional Conference sections (figure 1): • section 1 – Rapid solidification materials; • section 2 – Methods of coating application and research; • section 3 – Laser, electron-beam and ion-plasma methods of surface modification; • section 4 – Composite materials and permanent joints; • section 5 – Works of young scientists. The Conference was opened by Alexander Vladimirovich Bespalov, Co-Chairman of the Director of the Department of Materials Science and Materials Technology of the Moscow Aviation Institute (National Research University), who emphasized the importance of developing research in the field of physical and physicochemical methods of obtaining and processing new materials and coatings for the aerospace industry. He also noted the achievements of the Institute’s scientists in the field of laser coating and fast solidification materials.

One of the ways to achieve safety and comfort is to improve on-board air conditioning systems.The use of air cooling machine determines the air pressure high level at the point of selection from the aircraft engine compressor. Because of the aircraft operation in different modes and especially in the modes of small gas engines, deliberately high stages of selection have to be used for ensuring proper operation of the refrigeration machine in the modes of the aircraft small gas engines. Into force of this, most modes of aircraft operation have to throttle the pressure of the selected stage of selection, which, together with the low efficiency of the air cycle cooling system, makes the currently used air conditioning systems energy inefficient.A key feature of the architecture without air extraction from the main engines compressors is the use of electric drive compressors as a source of compressed air.A comparative analysis of competing variants of on-board air conditioning system without air extraction from engines for longrange aircraft projects was performed at the Moscow Aviation Institute (National Research University).The article deals with the main approaches to the decision-making process on the appearance of a promising aircraft on-board air conditioning system at the stage of its conceptual design and formulated the basic requirements for the structure of a complex criterion at different life cycle stages.The level of technical and technological risk, together with a larger installation weight, will require significant costs for development, testing, debugging and subsequent implementation, but at the same time on-board air conditioning system scheme without air extraction from the engines will achieve a significant increase in fuel efficiency at the level of the entire aircraft.

Introduction. The development of students' ability to make informed and responsible decisions in the field of personal finance is an urgent problem. Young people must have the appropriate competencies, have the required level of financial literacy. This also applies to students of non-economic areas of training, in particular students of technical specialties. The purpose of the study is to analyze the financial literacy of students of a technical university. Materials and methods. The material of the research was the data of an anonymous sociological survey of 100 students of Stupino branch of Moscow Aviation Institute (National Research University) of the 3rd and 4th courses of full-time education by filling in Google forms. Results. Analysis of students' opinions showed a positive trend (65% of respondents) for the introduction of financial literacy in the educational process of a technical university. Students admitted (54% of respondents) that they are not aware of all kinds of risks when investing in NPFs, when buying a home, compulsory motor third party liability insurance, taking a loan, when calculating wages, etc. Based on the students' answers, it was found that 62% of the respondents had no experience in solving financial issues. At the same time, 67% of students are not interested in rates on deposits, loans, the key rate of the Central Bank, but daily use the financial services of the bank (plastic cards, payment for services via the Internet, e-wallet, etc.) 97% of students. Conclusion. Today, the financial literacy of the population is fraught with many vital issues and affects the effectiveness of decisions made and the associated risks.
