    Letecké multispektrálne snímkovanie v poľnohospodárskom odvetví
    (University of Žilina, 2024) Šmidt, Marco; Veľký, Patrik
    This thesis focuses on the possibilities of applying airborne detection in many bands. Possibilities of multispectral detection in direction of use such as animal monitoring or scarecrow placement. In another direction of using thermal imaging for finding temperature anomalies or obtaining information from UAV sensors to improve economics in agriculture, light reflectance, electromagnetic spectrum, comparing satellites and UAVs in agriculture, and vegetation indices. The analysis of the studies was based on simulations and calculations followed by laboratory tests and external measurements. Using certain sensors operating in the corresponding regions of the frequency spectrum, the detection ranges of the drones were used to find the outputs derived from the calculated and simulated values, where a comparison of the studies followed.

    New trends in UAV construction
    (University of Žilina, 2023) Iakovlieva, Anastasiia; Bugaj, Martin
    Aviation is one of the fastest developing segments of transport, the development of which did not bypass the construction of unmanned aerial vehicles. The main purpose of this paper is to analyze current trends that may affect the development of unmanned aircrafts in civil aviation. For the purpose of researching new trends in the construction of unmanned aerial vehicles, is needed to define today's state of development and also to divide UAVs by the type. In conclusion, the goal of the article is to define the direction in which the development of construction solutions is currently going and what the potential development in the use of UAVs new trends can bring.

    Analysis of alternative control options fot the ROTAX 915 is engine
    (University of Žilina, 2023) Plochová, Jana; Šajbanová, Kristína
    This article focuses on analyzing the possibilities of alternative management of the ROTAX 915 IS aircraft engine using the ECU MASTER electronic control unit. The article examines how the use of ECU MASTER could become a beneficial alternative to the traditional manufacturer's control system. The new control system would ensure lower costs for purchasing ECU and reduce the number of sensors required to operate the engine. This would achieve a lower weight of the entire system, which is very important for aircraft in terms of fuel efficiency and cost savings.

    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.

    Analysis of new progressive diagnistic methods in the area of aircraft maintenance
    (University of Zilina, 2021) Supuka, Matej; Hrúz, Michal
    In the area of aircraft maintenance, we commonly meet with the problem of corrosion, detection of which is one of the primary obstacles. Implementation of modern sensing techniques has a potential to bring many benefits. The objective of this work is to analyze technologies, their potential applications, and viability of switching to autonomous detection using computer aided sensing. Primary source of information were research articles from science databases such as ResearchGate and ScienceDirect. Available documents were analyzed and subsequently, useful information was extracted. First part deals with theretical knowledge about corrosion, based on which potential technologies were chosen. Those were then described, and their viability was analyzed, based on how well they could achieve our goals. Selected technologies have shown potential, however necessary solutions could not be found to enable fully switching tou autonomous computer detection. Although data acquired show many potential benefits that could arise from partial implementation of these technologies combined fith old fashioned visual inspection.
