Súčasný stav a rozvoj systému pohybových plôch na letisku M. R. Štefánika
(University of Žilina, 2024) Adamík, Jozef; Kazda, Antonín
In view of the dynamic development of air transport, it is essential that airport infrastructure is adapted to the requirements of modern aircraft. The thesis analyses the historical development of the infrastructure of M. R. Štefánik Airport (BTS). This research involves guided interviews and questionnaires with seven experts of practice who provided insight into the current state of the BTS airport. These experts were selected from five different areas, including BTS Airport, Air Navigation Service Provider (LPS), noise and vibration assessment (Euroakustik company), runway systems capacity, and the perspective of the Bratislava Metropolitan institute. The aim of the thesis is to propose appropriate recommendations for BTS Airport, the main proposal being the use of one runway (RWY) in 'mix mode' instead of using both RWYs at the same time. This proposal is supported by the cost of the RWY reconstruction, which has been compared with other airports in Europe and North America. To validate the capacity of a single RWY, the Airfield Capacity Spreadsheet Prototype Model (ACRP 79) will be used, in which several inputs have been adjusted according to BTS airport operations such as: aircraft operating from BTS airport, aircraft separations, aircraft approach speeds, and RWY occupancy time. The model simulates operations in August and December 2023 and projected operations in 2028. Other recommendations include modification of some taxiways (TWY), apron modifications, and analysis of the use of jetways on the apron stands. Finally, the impacts of a possible restriction of airport Curfew at BTS are also being examined.
Výpočet a optimalizácia venca lopatiek plynovej turbíny experimentálneho motora
(University of Žilina, 2024) Martincová, Alexandra; Čerňan, Jozef
The thesis deals with the calculation and optimization of the stage of the gas turbine distributor vanes of an experimental engine. The aim is to create an experimental turboshaft engine by combination of the Saphir 5 auxiliary power unit and a free gas turbine with a gearbox, derived from the TS-21 turbine starter. Through calculations, it is necessary to determine the optimal geometric parameters and the resulting number of stator vanes in order to design a 3D model of the gas turbine stator shroud as a connecting element between the Saphir 5 and the free gas turbine, which consists only of the rotor blades. The results of the work and the evaluation consists of calculations of the thermodynamic circulation of Saphir 5 and calculations of gas turbines. It also contains the design of the stator ring of a free gas turbine, as an intermediate member or flange of two aggregates creating an experimental engine. The 3D model and optimization is created using the Creo 7.0 program, which are based on the calculation of the gas turbine itself. In the end, we will get to the answers and to the summary of the results that created the exact design of the experimental engine.
Trhové stratégie v BA so zameraním na Spojené štáty americké
(University of Žilina, 2024) Bendík, Dávid; Tomová, Anna
This paper discusses market strategies in business aviation with a focus on the United States. The first part of the paper is devoted to the definition, origins, and historical evolution of business aviation. It also includes an appraisal of the global significance of BA with an emphasis on Europe and the United States. The second part of the paper explains why it is beneficial to analyse market strategies in BA in the United States. Close attention is given to two highly important market strategies. The third, practical part of the paper provides essential data on the nineteen business airlines discussed by the author, along with an analysis of their fleet structure. In this part, the paper also focuses on the market tenure of the individual BA companies, offers a comparative analysis of their product portfolios, investigates acquisitions and collaborations, and characterizes the United States business aviation segment using Porter’s Five Forces analysis. The last part of the paper is dedicated to the interpretation of the main findings. The analyses conducted in the paper were based on business airline websites, aviation internet magazine articles and a research website that concentrates on the business aviation sector.
Podnikanie v civilnom letectve v SR a jeho špecifiká
(University of Žilina, 2024) Ďuricová, Ema; Novák Sedláčková, Alena
The paper deals with business activities in Slovak civil aviation from the point of view of connecting international legislation with national legislation. There are described the conditions of business activities, the requirements associated with the receiving of licenses and approximates the connection of general legal regulations of business and labor law to civil aviation. It defines the key European Union regulations and their relationship to national legislation. It analyzes business relations and their impact on the development of aviation, as well as the impact on business activities and the Commercial Code general conditions as lex generalis. In order to define specifics, it compares the commercial law legislation of the Slovak Republic with the Czech Republic in the primary features of establishing legal entities of airlines or airports. The paper is focused on the labor relations in aviation, as well as the issue of established trade unions. It deals in detail with the analysis of the impact of the pandemic caused by the spread of the disease COVID-19 on the civil aviation labor market as well as changes in legislation. The last part of the paper tried to identify all necessity procedures for an airline licensed in the Slovak Republic.
