    Design and construction of a UAV device with a fixed wing for the conditions of rescue services
    (University of Zilina, 2021) Petrík, Nikolas Michael; Pecho, Pavol
    The paper is focused on comprehensive design of an unmanned aerial vehicle with fixed wing, which would add efficiency to specific activities performed by rescue services. The current rapid development of unmanned aerial vehicles is slowly becoming part of many industries around the world. The aim of this paper is to design an unmanned aerial vehicle that could provide safe, reliable, and efficient operation. The overall design, construction, and installation of the proposed unmanned aerial vehicle should integrate several modern technologies. To make an ideal design of unmanned aerial vehicle it is required to possess the knowledge of current construction methods of additive manufacturing, understanding of legislation in operating conditions and, in addition to general knowledge of unmanned vehicles, also comprehensive skills in programming and configuration of autonomous control elements of autonomous unmanned systems. After the production of the unmanned aerial vehicle with fixed wing, very good technical properties were demonstrated during experimental ground tests. Achieved technical properties are comparable to those owned by the unmanned aerial vehicles that are currently on the market. The final design configuration using an infrared-sensitive optical device could perform activities such as: searching for missing persons in hard-to-reach and vast terrain or searching for forest fires.

    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..
