    Optimization and sustainability of conventional propulsion units in the context of current environmental trends
    (University of Žilina, 2023) Novák, Miroslav; Rostáš, Ján
    This article focuses on the current situation in the aviation industry in relation to environmental trends. In the introductory part, the situation on the aviation fuel market, their production and their current price is presented, while the emphasis is on familiarization with a more ecological form of traditional fossil fuels, namely sustainable aviation fuel. The reader is informed about the current situation in connection with emissions and greenhouse gases produced by air transport and the effort to reduce them and in the future their complete elimination. The second part presents the approach of aviation authorities such as EASA, FAA and ICAO, as well as their goals for reducing emissions and greenhouse gases and current projects for sustainable aviation. The article focuses on the implementation of sustainable aviation fuel in aviation and the issues associated with its use. The third part deals with the latest projects of aircraft and power units manufacturers. Other strategies such as CORSIA and ETS are presented, as well as climate conferences dealing with this issue. We point out the different approaches of countries in connection with the issue of reducing emissions. In the conclusion, we will evaluate the current situation with the economy and ecology in aviation from a global point of view, the actions of the authorities, manufacturers and point out the shortcomings.

    Prospects for the development of Bratislava Airport and the influence of relations between airlines and the airport on the decisions of the airport management
    (University of Žilina, 2023) Pojedinec, Benjamín; Rostáš, Ján
    The research deals with the development of Bratislava Airport Milana Rastislava Štefánika. The primary goal of the work is to evaluate the current situation at Bratislava Airport, its equipment, layout, continuity of services, operational performance and evaluation of the airport‘s allocated and used capacity. The research is divided into a theoretical and a practical part. In the theoretical part, it is necessary to present a theoretical view of the basic concepts in aviation, the history of Bratislava Airport, the historical development of the number of passengers transported at this airport, the development of airlines operating in Slovakia and their influence on this airport, a brief evaluation of the number of destinations to which Bratislava Airport flies and considering the possibility of specializing this airport as a secondary airport for Vienna Airport. The essence of the practical part is the evaluation of the current situation at the Bratislava airport, the analysis of privatization possibilities and the implementation of a qualitative survey using a questionnaire. Based on the analysis and evaluation from the survey of the opinions of interested subjects, optimal alternatives for the further development of Bratislava Airport are provided in the context of broader management relations with airlines, as well as an evaluation of privatization options and their potential contribution to the development of Bratislava Airport.

    Analysis of trends and possibilities of reducing waste production on board of aircraft and inovative systems for its assessing
    (University of Zilina, 2022) Juríková, Terézia; Rostáš, Ján
    A major trend in the 21st century is the protection of the environment from a global perspective, which is associated with reducing emissions and reducing waste production. Therefore, we try to apply the same trends in aviation. With the help of progressive technologies, we ensure the reduction of emissions. However, the issue of waste generated on board of aircraft during the flight is not comprehensively identified. This diploma thesis deals with the topic of reducing waste production on board. The main goal of this work is to analyze the current state of the problem and the subsequent creation of innovative solutions in the form of operating procedures for organizations operating in aviation. The laws and directives valid in the territory of the Slovak Republic in the application of relevant regulations and other EU legislation were used to prepare the work. Articles, studies and methodologies of foreign authors have contributed appropriately to the completion of the theoretical part of the thesis and to a better understanding of the issue. The first chapter presents the current situation and legislative requirements in the field of waste generated on board aircraft. The second chapter describes waste recovery processes and related processes such as landfilling, incineration and recycling. The possibilities of using alternative materials and the application of optimal recycling technologies are described in the third chapter. The practical part of the work was the creation of progressive procedures on board aircraft and in handling or catering companies. At the end of the work, the impact of the created procedures on the environmental, socioeconomic, and operational environment is described.

    Aircraft recycling system optimalization and aircraft sections re-use possibilities after the end of their economic life
    (University of Zilina, 2022) Chebeň, Juraj; Rostáš, Ján
    Purpose of this article is to evaluate re-use of sections from retired aicraft for further usage and additional optimalization of recycling and re-use of materials used in aircraft construction. With hundreds of commercial airplanes retired every year, the need for innovative approaches in recycling process rises. The concept of re-using parts from retired aircraft is not new. Before scrapping, valuable parts are of course stripped of the airplane. The article assesses if there is possibility to re-use parts and sections that usually end up scrapped in aviation and under which circumstances. Its first part is focused on analysis of procedures currently utilized during aircraft recycling, including brief description of decomissioning process, current state aircraft recycling in general, processes of disassembly and dismantle, existing facilities, description of recycling of alloys and composite materials. Second part deals with legislative, technical and environmental options of aircraft recycling and re-using aircraft sections. Third part focuses describes current parts market, together with proposal how to make it more efficient, current and possible future trends concerning aircraft recycling and re-use of materials and comparison of recycling between USA and Europe
