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 Návrh riešenia riadenia skupiny UAV(University of Žilina, 2024) Gúcky, Jozef; Bugaj, MartinThis thesis addresses the challenges and solutions to the management of groups of unmanned aerial vehicles (UAVs). Using a comparative analysis approach, the research evaluates UAV group management methods in terms of their effectiveness under various criteria. The findings suggest that swarm algorithms, inspired by the collective behavior of natural systems, offer a better approach to achieve decentralized, adaptive, and scalable control of UAV groups. This thesis contributes to this field by providing a comprehensive analysis of UAV group management strategies and demonstrating the benefits of swarm algorithms across a variety of criteria. This research has implications for enhancing the capabilities and effectiveness of UAVs in applications such as search and rescue, environmental monitoring, etc.Item Automatický bezpilotný klzák ako nosič aerologických sond(University of Žilina, 2024) Kapustík, Samuel Michal; Pecho, PavolUnmanned aerial vehicles are increasingly being used to make our lives more enjoyable and easier, whether through the ability to capture key moments in our lives in high definition, or by automatically mapping hard-to-reach terrain, or even significantly assisting in the search for missing persons. This thesis discusses and approaches the possible expansion of the usability of unmanned flying vehicles, along with a proposal to create a more economical and environmentally friendly way of using aerological probes, such as the Vaisala RS41, to provide us with invaluable data needed to create accurate weather forecasts. Furthermore, the procedure for setting up such an unmanned flying vehicle using an advanced autopilot system is explained, and this thesis also includes specific results achieved in the experimental work associated with it. With the proposed solution, it will be possible to use the funds allocated to meteorological research and measurements.more efficiently.Item Inovatívne technológie a nástroje v procese údržby lietadiel(University of Žilina, 2024) Štefaňák, Mattiás; Janovec, MichalThis master thesis aims to analyze and evaluate innovative technologies and tools through new aircraft maintenance. Through a series of extensive theoretical studies and data obtained during real-life cases, this work will aim to identify the latest trends behind this process and evaluate the impact they have on production, safety, maintenance costs. The most complex theoretical section of the work will be related to such an area as a current state of aircraft maintenance, which in turn will have to integrate dependent trends, such as predictive maintenance, digitization, and state-dependent methods. This part of the work will present the latest technological trends of the industry, such as artificial intelligence and machine learning, 3D printing, augmented reality and virtual reality .The main part of the work will examine the advantages and disadvantages of these technologies, forms of use of AMO technologies, and proposals for improving technologies, such as improving the current use of electronic tablets in the maintenance process, as well as a proposal for the use of AI within the anti-collision system for movement and manipulation of flight on the ground.Item U-Space v podmienkach slovenskej republiky(University of Žilina, 2024) Bejdáková, Natália; Pecho, PavolUnmanned aerial vehicles are a dynamically developing industry. With the increasing number of remotely piloted aircraft, emphasis is being placed on ensuring safe operation in shared airspace with manned aircraft. In the countries of the European Union, including Slovakia, the concept of U-Space is gradually being implemented. The bachelor thesis is focused on the analysis of the current situation in the operation of unmanned aircraft, current legislation, operation rules, and implementation of the U-Space concept in Slovakia. Attention is being concentrated on explaining the concept of U-Space and defining the services, including the responsibilities and obligations of the entities present in this system. The thesis proposes a set of possible implementation solutions to ensure more efficient and faster development in Slovakia. Based on relevant proposals, specific examples of how the situation would change after the implementation of the selected proposals are pointed out. An analysis of the findings based on collected data from the questionnaire is given to determine the level of awareness of the U-Space concept and the improvement of the educational situation in Slovakia. Finally, the technical and economic aspects of U-Space implementation are being evaluated and possible pros and drawbacks are identified.Item Technicko-prevádzkové charakteristiky pre rôzne aplikácie UAV(University of Žilina, 2024) Valetskyi, Maksym; Veľký, PatrikThe goal of this bachelor's thesis is to create a system for analyzing technical and operational characteristics for various UAV applications. The work consists of 4 parts: the first part describes the current methods of qualification and separation of drones according to the above mentioned parameters, the second part analyzes in detail five different ways of using drones, the third part of the part selects the most important technical and operational ones based on the data from the previous part parameters and a table is created. In the last practical part, with the help of logical analysis, cause-and-effect relationships, methods of assumptions and results of the research, the relationships or so-called correlations entered in the table are investigated between the values listed in the table. This model helps to optimize the operation of the drone, save money on the purchase, maintenance and increase the safety of its operation.
