Item Item Development of flight instruments for general aviation aircraft(University of Zilina, 2022) Ďuricová, Ema; Kandera, BranislavGiven the constantly evolving offer proposed for aircraft equipment, the aim of my work is to describe the innovations, that have been implemented in aircraft instruments. The content of the work is divided from the very beginnings of aircraft instruments and their gradual use and expansion. Subsequently, I deal with the data that are displayed by the devices, but also their design and the comparison of the current state compared to the initial versions. Innovations of aircraft instruments are focused on both components and the display of flight data, which leads to simplification of their operation and individual assembly. One of the advantages of modern instruments is their ability to detect errors that may occur during the flight, which serves the pilots to ensure the flight. Furthermore, I focused on the system of collection, processing and evaluation of information, as well as their final production on board the aircraft. My work is mainly focused on the Dynon system, whose functions, display and implementation I described in detail, use and design in aircraft cockpits. The main goal of the thesis is additional processing of information for the subject Aircraft Instruments I and their processing from the student's point of view.Item Proposal for modification of the L-13 “blanik” sailplane’s wing hinge structural design(University of Zilina, 2022) Mrakvia, Dominik Michael; Trško, LiborAs a result of a tragic accident in Southern Austria, all L-13 “Blanik” sailplanes were grounded. During this accident, the factory structural design failed, even though the plane underwent all mandatory inspections and repairs. The intention of this article is to introduce the possibilities of structural modification of this aircraft, specifically its wing beam and hinge. Already existing modifications are described, as well as new ones with the aim to strengthen its critical parts. Structural modification of the wing hinge and beam, replacement of rivet joints with stronger Hi-Loks and use of different hole angles to ensure a firmer joint and better stress distribution around these holes are covered. Last two beforementioned modifications are described in more detail, a tensile test is carried out and its results are compared to the results of the control samples. In the end, viability and practicability of these modifications are discussed.Item Changes in airport infrastructure caused by the historical development of aircraft(University of Zilina, 2022) Adamík, Jozef; Kazda, AntonínThe airport infrastructure is constantly influenced by the development of aircraft. It has always been, that the aircraft was first designed, and based on its performance parameters and geometrical characteristics, a space for the airport were sought to serve the new aircraft. Even today, we can see the different development of aircraft in different aircraft manufacturers, which determine how the airport infrastructure will change in the future. In the introductory chapters, we analyze several aircraft requirements for airports that have been affected by changes in ground infrastructure and the subsequent development of airports. The main objective of this bachelor thesis is to document the changes in the airport infrastructure caused by the historical development of aircraft. The discussed development of aircraft and reaches out from the beginning of aviation to the end of World War II through the era of jet aircraft to large-scale long-haul aircraft. Based on the creation of a database of aircraft and a description of typical aircraft representatives of the period, an analysis of their parameters and the described impact on selected airports is performed. Three historical international airports were selected for a detailed analysis of airport development. There are two analyzed airports in Europe: Munich Riem together with Munich - Franz Josef Strauß and Amsterdam Schiphol. In the United States, John F Kennedy Airport is chosen near New York City in terms of the highest airline utilization. Until 1951, selected airports were analyzed from historical footage and, after the publication of ICAO Annex 14 Aerodromes, also documented by changes in the regulation. Airports had to adapt to changes in environmental requirements and the introduction of new technologies in the form of more fuel-efficient and smaller commercial aircraft. One of the benefits of the thesis is to emphasize the need to plan airport changes in relation to the needs of aircraft technology in the future. This area includes the planning and modernization of runways (RWY), terminals, aprons and stands. At present, RWY design pays attention to reducing noise in suburban areas, reducing turn-round time at stands by using jetways, the number of taxiways (TWY) connecting the RWY to the airport and operating aircraft with a smaller code letter.Item Monitoring of technical state of unmanned aerial vehicles(University of Zilina, 2022) Lagin, Samuel; Kandera, BranislavThe aim of this work is to study current possibilities of monitoring the technical state of the unmanned aircraft from the most basic activities to the more advanced aircraft systems. Partial goal is to create a simple general maintenance checklist for cases when the manufacturer does not publish any maintenance procedures, or the manufacturer is the owner and pilot of the aircraft, in case of DIY aircraft. Theoretical part is devoted to description of most common components of current UAVs and their possible failures and stating current possibilities for maintaining awareness of the technical state of the aircraft prior to, during and after the execution of a flight. Second part will state how to extract the flightlogs and what tools can be used to analyze them. The result of this work is creating general maintenance checklists as well as stating the information about the process of modifying this checklist for the UAV in question. Mentioned checklists will be created for pre-flight, post-flight and regular maintenance check.Item Innovation options for selected systems of M60 engine: exhaust system and engine cooling(University of Zilina, 2022) Lapínová, Branislava; Čerňan, JozefOur article deals with the design and construction of a resonant exhaust system and cooling system for the M60 engine. In introductory part, the article provides the reader with a final overview of two-stroke. In the next chapter, the focus is only on the resonant exhaust system. The article of the reader informs about the basic principles of resonant exhaust systems and points out their fundamental effect on power, torque and fuel consumption. Subsequently, the article gets to the calculation of the resonant exhaust system and its execution. The final chapter deals with the cooling system and solves the design optimization of the shape of deflectors. Both in the previous chapter and in this chapter, it first deals with theoretical knowledge, design and subseguent production of deflectors.Item Innovation options for selected M60 engine systems: ignition system and engine parameter monitoring(University of Zilina, 2022) Suchanovský, Matúš; Čerňan, JozefThe topic of this paper is the possibility of innovating the ignition system of the M60 engine. The main part is the practical solution of the assignment. It shows the condition of the original ignition system, which was innovated in this work. It was a contact ignition system with a fixed advance, using a system of hammers. This solution was replaced by a new type of ignition, specifically an electronic ignition system that allows to change the ignition advance depending on the engine speed and load. The main parts of the new system consist of a control unit and a Hall sensor. It is these two components that make the main difference compared to the original ignition system. We deal with a more detailed description of design, construction and installation in the practical part. We paid attention to the design, the wiring diagram and its installation. At this stage, we addressed the possibilities of fastening a Hall sensor. The use of old components for assembly was not possible, so we proceeded to the design and production of new ones. The innovative ignition system will allow the engine to achieve higher power, lower consumption and the proportion of pollutants in the exhaust gases.Item Ownership structures of regional airports(University of Zilina, 2022) Szotkowski, Nicolas; Remencová, TatianaThis paper is focused on regional airports and their ownership structures. The first part defines the basic terms such as airport and regional airport from a legal point of view. It describes airport ownership models in general, focusing on the traditional organizational ownership model, and then it describes processes such as decentralization, corporatization, commercialization and privatization. This part also contains the advantages and disadvantages of privatization. In the second part, it is focused on the current state of the issue, when there are described selected scientific studies that address the issue of ownership models. Attention is also focused on the Covid-19 pandemic, which had a strong impact on the regional airport. The main goal of the paper is to analyse the ownership structures of selected regional airports, which are located in Austria and the Czech Republic. In connection with ownership structures, it also monitors the achieved economic result of regional airports.Item Morphing wings of aircraft(University of Zilina, 2022) Jackuliak, Jakub; Bugaj, MartinGoal of the paper is to describe use of morphing wings on aircraft and their possible use to increase aerodynamic efficiency of aircraft.

Since 2021, new European legislation has come into effect regulating the flight crew licensing. Part of this legislation is the obligation to attend a seminar for each instructor once every 3 years. The seminars can be organized by the declared training organizations (DTO), for which the organization of these seminars is new and have no experience with it, so this program proposal can help them organize the seminar. This research deals with current legislation, analysis of conditions imposed by EASA, analyses the current recommended flight instruction syllabus for new flight instructors together with the syllabus for training new pilots, analyses selected aviation accidents and finally analyses important chapters in aviation medicine.
