Item Danger of icing when operating unmanned aerial vehicles(University of Žilina, 2022) Ondrejková, Ivana; Kandera, BranislavThe paper examines icing on Unmanned Aerial Vehicles (UAV) during the flight. We chose the Mavic Pro and Mavic 2 Pro UAV by company DJI to carry out the research. Research flights are performed during the early morning hours with meteorological conditions suitable for icing. We use the AirData application to analyse flight data. The aim of the work is to find out how dangerous icing is, what meteorological conditions are suitable for icing, how fast icing is formed during the operation of an unmanned aircraft and how it is possible to suppress or eliminate icing. In introduction of this work elaborated theoretical knowledge about the formation of icing and its types. Subsequently, the negative effects of icing on the flight are described, such as changes in lift, drag, controllability of the aircraft and others. The following section describes the accidents of UAV due to the impact of icing. After analysing the data from the mentioned application, we proposed recommendations for pilots of UAV. Before the flight, we recommend checking the meteorological forecast, focusing on the temperature and humidity at the flight area, usually up to 120 meters above the Earth surface. In-flight recommendations include monitoring rotation speed of propellers and frequent inspection of propellers in meteorological conditions suitable for icing and others.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 Inspecting activities with unmanned aerial vehicles in the energy industry(University of Zilina, 2021) Beszédes, Vladim; Kandera, BranislavThe paper acquaints the reader with the use of unmanned aerial vehicles in the energy industry. The first chapter is devoted to the distribution of unmanned aerial vehicles and the distribution of energy as a sector where, according to individual categories, the activities of UAVs in a specific category are described. The second chapter discusses in detail the situation in Slovakia, what legislative acts are subject to inspection activities and to what extent the use of UAV is represented in individual categories of energy in Slovakia. In the following pages, we performed an exemplary high-voltage inspection flight and described the necessary steps to perform a safe flight. In the last fourth chapter, the findings and findings related to the paper and the final summary are evaluated.Item The use of unmanned aerial vehicles in the mountain rescue service(University of Zilina, 2021) Gánovský, Martin; Kandera, BranislavThe theme of paper is the use of unmanned aerial vehicles in the Mountain rescue service. At the beginning, a brief summary about the history and development of unmanned aerial vehicles is made, starting from the very beginning to their gradual integration into the rescue systems all around the world. This part is followed by an analysis of the currently valid Slovak legislation regulating the rules of flying with unmanned aerial vehicles on the territory of Slovak Republic, which also affects the flight operations of mountain rescuers. Author also included an analysis of the European legislation, which should gradually replace the currently valid Slovak legislation and unify the rules of operation of unmanned aerial vehicles on the territory of the member states. The third chapter describes the use of specific types of unmanned aerial vehicles used by the Mountain rescue service of Slovak Republic and also of other European countries. We focused on the operational advantages and disadvantages compared to other types of aircraft technology used in the mountain rescue systems. The last part consists of an analysis of available equipment used in conjunction with unmanned aerial vehicles during avalanche accidents. Part of the work is also researching the possible extensions of mountain rescue operations by the implementation of modern avalanche beacons attached on the unmanned vehicles. In a research we focused mainly on the possible interference caused by the operation of unmanned aerial vehicle in close vicinity of an avalanche beacon.Item Anti-collision systems of unmanned aerial vehicles(University of Zilina, 2021) Višnai, Kristián; Kandera, BranislavThe main goal of the paper is to summarize the knowledge about anti-collision systems of unmanned aerial vehicles. In the work are also described currenly used anti-collision systems of unmanned aerial vehicles. The work contains practical research in which we tested anti-collision systems of DJI Mavic 2 Pro. The purpose of the research was to find out how this unmanned aerial vehicle can avoid static obstacles. The second part of practical research is the analysis and comparison of systems that provide anti-collision actvity between unmanned aerial vehicle and aircraft in the vicinity. Part of the work is also the evaluation and selection of a cooperative anti-collision system for DJI Inspire 2. The conclusion of the papercontains a summary of the findings that we have obtained based on the analysis of available facts and using operational experience.
