Item AEROjournal - celé číslo 2/2024(University of Žilina, 2024)Item Combustion engine piston modifications for better performance in UAV aplication(University of Žilina, 2024) Lubják, Peter; Čerňan, Jozef; Nichtová, RadoslavaThe issues described in the article are largely an overview and explanation of the functions of various modern modifications to internal combustion engine pistons, which significantly increase the performance and reliability of current power units with a minimum amount of technical implementation. Especially the modification in the form of gasporting can indicate the direction that will soon be possible to take when modifying engines.Item Aerodynamic optimazation of long endurance UAV wing(University of Žilina, 2024) Jackuliak, Jakub; Dianovský, Róbert; Bernátová, BarboraWith recent growth in UAV sector, UAVs are progressively used more than ever before. With growth of UAV use is closely tied growth of possible uses of such aircraft. Missions conducted by any aircraft put requirements on the aircraft itself. This leads to necessity of optimization of aircraft for specific mission profile to maximize its mission efficiency. This article focuses on optimization of UAV wing for long endurance flight.Item Fatigue in the air and at sea: comparing impact and regulations in aviation and maritime transport(University of Žilina, 2024) Maternová, Andrea; Materna, Matúš; Nichtová, RadoslavaFatigue poses a significant threat to transportation safety across all modes of transport. This paper examines fatigue, its consequences, and the regulatory frameworks addressing this issue, with a focus on the aviation and maritime industries. A comparative analysis is conducted on differences in legislation governing maximum duty hours, mandatory rest periods, and the risks resulting from non-compliance. By highlighting regulatory differences and their implications, this paper underscores the importance of effective fatigue management to enhance safety in both sectors.Item Municipal aviation functioning as one of future types the aviation activities(University of Žilina, 2024) Alekseev, OlehThere are represented the basic principles of municipal air transport within the metropolis. The main tasks of creating municipal transport are defined to further develop of aviation technologies for municipal economy and life support of the city and its air-transport system. In order to further development of aviation technology in the interests of the urban economy and life of the city, its air transportation system is necessary to decide three main objectives: development of aviation equipment and saturation of City Aviation park by light helicopters which will ensure solving of special tasks for the benefit of urban services, commercial transportation and air operations; development of urban aviation infrastructure, including heliports and helipads; the organization of safe use of the airspace over the city. The use of technology in aviation can be done while ensuring sanitary and environmental standards of environmental protection.Item Implementation of single European sky: overview of activities in Slovak republic(University of Žilina, 2024) Boháčová, Andrea; Badánik, BenediktLocal Single Sky implementation monitoring (LSSIP) serves as a structured, localized framework that translates the high-level goals and policies of the Single European Sky (SES) initiative into actionable steps at a regional level. It is structured in such a way that it defines the specific actions required at a local level and the performance indicators that will be used to monitor progress. It is part of an integrated system aimed at improving the management of European airspace. This paper provides general characteristics of the LSSIP, including key external and internal roles, describes status of the implementation activities in Slovak republic and outlines future direction of the programme.Item AEROjournal - celé číslo 1/2024(University of Žilina, 2024)Item Konštrukcia UAV typu VTOL s náhradou mechanického riadenia rotorov softvérovým systémom(University of Žilina, 2024) Michalík, Matúš; Pecho, PavolThe article focuses on the construction of an unmanned aerial vehicle (UAV) with vertical take-off and landing (VTOL) capabilities, inspired by the American military aircraft V22 Osprey. The main goal of the paper is to design and construct the UAV using software control based on the "virtual swashplate" concept. The paper covers the design, construction, testing, and evaluation of the UAV, including a control system based on a PID control system. Individual chapters are dedicated to the initial design of the UAV, wing construction, main rotor, "virtual swashplate" software solution, control system, and finally, testing and evaluation of the constructed UAV. The paper provides a comprehensive overview of the design, construction, and testing process of a VTOL UAV, focusing on the use of software control and innovative technological solutions.Item UAV systémy v procesu sbírání údajů pro využití ve vodním hospodářství(University of Žilina, 2024) Michálek, Tomáš; Červeňanská, MichaelaOnce every few years there is a necessity to measure the transverse profiles of watercourses within the water management of the Slovak Republic. These are particularly important for the creation of 3D models of watercourses, which aresubsequently used to delineate floodplains or as a means of simulating the maximum possible water flow through a given watercourse. However, the current method of data collection for creating these 3D models is very lengthy and inefficient. Thus, this research is concerned with the design of a new method of data collection for the creation of 3D models, specifically using an unmanned aerial system (UAS) consisting of an unmanned aerial vehicle (UAV) and a laser surface scanning technology (LiDAR) device. The objective was to create a 3D model of the crosssectional profile of the selected drainage channel on Rye Island using the proposed UAS, to compare the measured data using an alternative method of measuring the channel bed by technology currently in use (GNSS receiver) and finally to compare the measured data with archival data. Although the proposed UAS measurements showed unquestionable qualities in terms of frequency and speed of data collection, the values measured by the UAS were often inaccurate and did not correspond to reality, mainly due to the high water pollution in one of the monitored areas. For this reason, the proposed method of data collection is particularly suitable for measuring watercourses with a minimum amount of clean water. Unfortunately, there are not many of these watercourses in Slovakia, so this method is not suitable for frequent use in the conditions of water management in the Slovak Republic.Item Vykonávanie bezpečnostnej ochrany civilného letectva(University of Žilina, 2024) Molčan, Tomáš; Novák Sedláčková, AlenaThis paper aims to clarify the implementation of civil aviation security focused on the legal regulation of reliability. The aim of the paper is to analysis and compare the development and differences of the unlawful acts and backround checks legislation from the beginning until today´s standards within national and EU legislation. It discusses the various regulations, conventions, and laws that have contributed significantly to raising the level of civil aviation security. The paper addresses the competence of security personnel, focusing on the individual skills and knowledge required for employment in the different sections of security. A important part is the analyse of the legal regulation of the vetting of persons working in the civil aviation concerning its necessity nowadays, focusing on the national standards and legislation in the countries of Central Europe, as well as the approach of the Slovakia to the implementation of these standards. The paper focuses on the analysis of the legal regulation in the field of background checks and security reliability in the selected EU countries with a focus on Central European countries such as Slovakia, Austria, Poland, and the Czechia. Subsequently, a comparison of the approach to background checks of the selected states is also important. In conclusion, the paper points out the possibilities of the modification of the current Slovak national legislation in the field of civil aviation security using legislative processes and amendments or additions to the Civil Aviation Act, pointing out the approach to this issue by the Transport Authority and airlines.
