    Possibilities of using unmanned aerial vehicles in forestry and agriculture
    (University of Zilina, 2021) Ďatko, Ondrej; Kandera, Branislav
    This work analyzes the penetration of the aviation, forestry and agriculture sector and aims to present forestry and agricultural activities where there is the possibility of using unmanned aerial vehicles. In the first chapter, the work deals with the characteristics of unmanned aerial vehicles, remote sensing, forestry and agriculture. The second chapter deals with a particular analyzes of scientific papers, articles and internet research, and on the basis of these analyzes presents examples of activities in which unmanned aerial vehicles can be used. The third chapter provides an overview of technological and software equipment needed to perform such activities or aerial work. In the fourth chapter, through the practical part, work focuses on examining the use of the mid-class unmanned aerial vehicle model for the plant health analysis, while providing justifications and findings from the results. As part of the practical part, it also provides practical information for the individual steps during the planning and operation of flight. In the fifth chapter, the work briefly summarizes the information and results collected, from which it suggests some possibilities for the use of unmanned aerial vehicles, such as their use in the vaccination of foxes, and the recommended procedures for operating flights or aerial work.

    Design of the reference model of the aero l-39 aircraft
    (University of Zilina, 2021) Staňa, Ján; Škultéty, Filip
    The object of the research of the paper is to design a reference model of an unmanned aircraft according to the model of the training jet Aero L 39. The work contains an analysis of the methods, procedures and typology used in the creation of reference models. Subsequently, the design of an unmanned vehicle was created using computer modelling, which was subjected to aerodynamic simulations and strength analysis. Aerodynamic performance was investigated on the airframe of the aircraft and strength analyses were determined on specific structural elements. After successful program tests, a functional model of the aircraft was built. The prerequisite was mainly aerodynamic analyses, which should determine with sufficient accuracy the basic structure of the model's flight. The result of solving the problem is a functional model of the aircraft, which is suitable for flight tests using appropriate hardware.
