    VYUŽITIE AUTONÓMNYCH SYSTÉMOV UAV PRE PODMIENKY ZÁCHRANNÝCH ZLOŽIEK
    (Žilinská univerzita v Žiline, 2020) Leitner, Martin; Pecho, Pavol
    The use of drones is slowly becoming an integral part of our lives. They are used every day and new ways of use are constantly emerging in various areas. One of the easiest way is to use them for entertainment, but there are also a large number of professional users. Their largest users include the military, but they are also used for aerial monitoring, mapping and various other services. As in civil aviation, as well as for UAV users, it is necessary to correct the current legislation, which is also included in the work. In the paper we will investigate the use of UAVs by armed force and rescue units. In this area, they have the opportunity to make full use of their main advantage, and that is how to get to places where access is difficult. In addition, their use does not require a pilot on board and does not endanger his life, as is the case with helicopters. In this work, we will design a flight path for a drone to cover the area as effectively as possible and thus help the rescue services to be more efficient in the search for missing persons. The flight path design will be created in the Dronedeploy program and will be planned for three types of terrain at different initial settings to allow comparison of these flights. Tables and figures are added to each flight to help the reader better understand the flight suggestions.

    OPTIMALIZÁCIA VYHĽADÁVANIA OSÔB ZA POMOCI TERMOVÍZNEHO SKENU PROSTRIEDKOV UAV
    (Žilinská univerzita v Žiline, 2020) Nosál, Ľubomír; Pecho, Pavol
    The main aim of the paper is to optimalize person search by using UAV with infrared camera. Author’s goal is to confirm experiment which he came up with and to also confirm theoretical knowledge about the discussed matter. The objective of the paper is to look at the problem from as many views as possible. Every point of view has to be analyzed and optimal solution for the problem should be found. In order to use technical devices one has to understand how the machines work and understand the basic pricinples which the machines are based on. Working principles of infrared cameras are interpreted also the radiation which every object emits and which the camera scans is described. In the master paper are analyzed study cases from real search and rescue missions. The solutions of these study cases are proposed by using UAV with infrared camera. The most important part of the paper is the experimenthal phase. The optimal angle which the camera is mounted under the UAV is solved and discussed. Also the factors which affect the camera during the flight are evaluated. At the end of the paper one can find concept how to fight COVID-19 by using knowledge acquired from the paper.

    RIEŠENIE VTOL PRE UAV S FIXNÝMI NOSNÝMI PLOCHAMI
    (Žilinská univerzita v Žiline, 2020) Sisák, Tomáš; Škultéty, Filip
    This paper focuses on solving the problem of vertical takeoff and landing of an unmanned aerial vehicle with fixed bearing surfaces. The introduction describes the two most commonly used types of UAVs, emphasizing the positive and the negative properties of the UAVs. Furthermore, the work describes vertical takeoff and landing of aircraft and the design of the arrangement of airfoils and fuselage for individual UAV. The next chapter focuses on the selection of correct material and the process of building a UAV. The following chapter is devoted to the used electronics, describing each component separately, but at the same time, describing the electronic components necessary for the vertical takeoff and landing of the so-called pixhawk precisely. The main idea is to introduce the functioning of the sole component and the correct setting using a computer program. At the end of the work, there are calculations that are necessary to determine the operating values such as the speed range and the multiples for safe operations of the UAVs. These calculations are obtained computationally but also by simulation, using the XFLR5 program. With the help of this paper, reader can build, set up and fly with an unmanned aerial vehicle with fixed surfaces and vertical takeoff and landing by himself..
