    Design and implementation of an alternative Rotax 915is engine management system
    (University of Žilina, 2023) Psárska, Vanesa Viktória; Čerňan, Jozef
    The content of this article is design and implementation of an alternative Rotax 915is engine management system. In my research, I worked with a wide-spectrum control unit ECU MASTER designed for the optimization of the injection time of spark-ignition engines and also the control of the ignition advance taking into account several sensors of engine input parameters. The article was created as part of research into the issue of optimal control of piston engines. Current methods of controlling engines and their systems, in principle, allow very precise control of important systems of modern piston engines, especially with regard to the ignition and fuel system. The inclusion of microprocessor units with multiple options for input parameters allow the control unit to take into account even less important parameters, which, however, help the control unit to keep the engine running smoothly while maintaining high combustion efficiency. The elaborated design of a possible alternative engine control system is subsequently connected with the practical realization of this control system. The result of the research is the design of the control system of the Rotax 915is engine and the subsequent practical production and adjustment of the control unit under the name ECU MASTER, which verifies the universal applicability of such a unit for various combustion engines.

    Increasing the safety of operation of unmanned aerial vehicles in adverse meteorological conditions
    (University of Zilina, 2021) Psárska, Vanesa Viktória; Ažaltovič, Viliam
    Primary obstacle in using unmanned aerial vehicles are adverse meteorological conditions. To allow more usage options in day-to-day life, it is neccesary to increase safety in such conditions. The topic of this paper is analysing possible solutions. First part discusses the current state of art and describes systems currently used. It defined meteorological conditions such as low temperature, wind, humidity and low visibility. It describes their influence on usage of remote controlled aircraft and change in their flight characteristics. Next part is devoted to analysing possible solutions and their applicability. The objective was to find out how to increase safety during adverse meteorological conditions and which technologies are best for achieving this result. Selected technologies have shown great potential and options for increasing safety are plentyfull.
