    Prevádzková bezpečnosť bezpilotných prostriedkov s elektrickým pohonom
    (University of Žilina, 2024) Kalafut, Lukáš; Kandera, Branislav
    The increasing adoption of electrically powered unmanned aerial vehicles (UAVs) has raised concerns about their operational safety, particularly with regards to battery technology. Lithium-based batteries, commonly used in UAVs, pose unique safety challenges due to their potential for thermal runaway, overcharging, and physical damage. The aim of this paper is to investigate the operational safety of electrically powered UAVs, with a particular focus on their battery systems. Theoretical part discusses basic types of UAVs, their electric propulsion system and the different types of batteries used in UAVs, in particular their advantages and disadvantages as well as their composition. Then, the paper also briefly explores and introduces BMS technology and its functions. In the last section of this paper, we look at the principles and practices of proper battery handling.

    Technicko-prevádzkové charakteristiky pre rôzne aplikácie UAV
    (University of Žilina, 2024) Valetskyi, Maksym; Veľký, Patrik
    The 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.
