(Žilinská univerzita v Žiline, 2020) Butuk, Yosef; Ažaltovič, Viliam
This paper describes the current situation in the field of flying unmanned aircraft. It characterizes the legislative conditions in the Slovak Republic and the European Union and the areas of use of unmanned aerial vehicles. The main objective of the work is to analyze current trends that may affect the development of unmanned aircraft in civil aviation. The work also includes innovations in the field of unmanned aerial vehicles that could be implemented in the future. The conclusion of the bachelor thesis summarizes the results of the current analysis and predicting the future development of UAVs.
EFEKTIVITA VÝCVIKU PILOTOV NA DIAĽKU
(Žilinská univerzita v Žiline, 2020) Kandera, Branislav; Škvareková, Iveta; Ažaltovič, Viliam
Although the topic of unmanned aerial vehicles is very acutal, in most cases attention is paid to the safe integration of unmanned aerial vehicles in airspace, their uses and their reliability. But the safe operation of drones is based on the correct and effective training of drone pilots. The paper deals with the training of pilots of unmanned aerial vehicles, defining the scope of training and the possibilities of using UAV simulators for training. An important aspect is the complexity of knowledge about unmanned aerial vehicles, as training is not only a question of control skills, but also of theoretical knowledge of the UAV itself with which the flight is performed. Based on the measured data, it is clear that the simulator plays an important role during the training of piloting unmanned aerial vehicles, while providing a valuable basis for the transition to a type of fixed-wing flight configuration.
FMEA ANALYSIS OF AUTOMATIC RESCUE PARASCHUTE SYSTEM FOR CIVIL AVIATION
(Žilinská univerzita v Žiline, 2020) Pecho, Pavol; Gáborová, Miroslava; Škvareková, Iveta; Ažaltovič, Viliam
The article analyzes the topic of rescue parachute systems, with a focus on pilot parachutes used by civic aviation pilots in emergency situations. The work is in addition to pilot parachutes, focused and most ballistic rescue systems for aircraft and firing parachute systems, which fulfill an equally important role in aviation. The issue was analyzed by FMEA analysis, which was applied to the automatic rescue system. The outcome of this study is the evaluation criteria of current technical systems to reduce the risk number “R”. For each of the safety enhancement solutions, the article contains a separate proposal for technical improvements that are suitable for implementation in practice. Such solutions ultimately represent an increase in civil aviation safety as such.
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.
THE MEASUREMENT OF PILOT WORKLOAD
(Žilinská univerzita v Žiline, 2020) Škvareková, Iveta; Ažaltovič, Viliam; Pecho, Pavol; Kandera, Branislav
The article is focused on objective measurement of pilot workload during IFR flight. For the purpose of our research, we decided to use eye monitoring technology to record eye movements to determine the pilot's performance. Eye monitoring provides data on the number of eye movements,number of visual intakes, number of saccades, number of blinks, fixations and the durations of these. Our study incorporated overall six pilots divided into two groups: the experienced and inexperienced. The measurements were performed on the ELITE S923 flight simulator located at Žilina airport, Dolný Hričov. Measurement and analysis of the data showed that the pilots showed significant deviations when comparing the two pilot samples. We also demonstrated various scanning techniques during ILS and NDB approaches. The conclusion of our work summarizes the measurement results and the use of eye track technology in the future.
NÁVRH METODIKY VÝCVIKU A UDRŽATEĽNOSTI SCHOPNOSTÍ PILOTÁŽE BEZPILOTNÝCH LIETAJÚCICH PROSTRIEDKOV
(Žilinská univerzita v Žiline, 2020) Ažaltovič, Viliam; Škvareková, Iveta; Kandera, Branislav
While the density of UAVs operations grow in the airspace the demands on their safe operation are increasing. Nowadays, the risk of an unmanned aerial vehicle colliding with an aircraft with another unmanned aerial vehicle or object is high as ever before. It is this ever-increasing danger that is the reason for training remote pilots, who will be able to safely control unmanned aerial vehicles. The goal of this article is to propose a pilot training methodology for the multicopter configuration of UAV. In the future, the proposed methodology may contribute to the development of rules for the training of remote pilots. The proposed methodology can be used in the future as a guide for the safe operation of unmanned aerial vehicles for the general public.
PRAVDEPODOBNOSŤ NEHODY BEZPILOTNÉHO LETECKÉHO PROSTRIEDKU NA ZEMI V OBÝVANEJ OBLASTI
(Žilinská univerzita v Žiline, 2020) Ažaltovič, Viliam; Škvareková, Iveta; Pecho, Pavol; Kandera, Branislav
The study in this paper defines the amount of the possible ground casualty risk of randomly falling out-of-control UAV on a picked flight path, which was defined from the city of Žilina to the city of Martin, which were 29 km apart. For this area, the probability of a third party casualties caused by lose of control during the flight of UAV, was calculated. For these calculations was used the Equivalent Level of Safety approach. The conclusion provides recommendations for safety improvements during planning flight routes for unmanned aerial vehicles.
Use of artificial intelligence in unmanned aerial vehlice industry
(University of Zilina, 2021) Buday, Adam; Ažaltovič, Viliam
The aim of this paper is the analysis of the contemporary state of implementation of artificial intelligence in the area of unmanned aerial vehicles (UAV), and a proposal of further use of artificial intelligence systems in this area in the future. We analyse three essential areas in which artificial intelligence systems are currently being implemented to some extend – path following, object detection and tracking, and anti—collision systems. In each mentioned area we apply different solution methods, technical requirements, but also advantages and disadvantages of those solutions. We present an overview of artificial intelligence as a scientific branch. Finally, we present an overview of how artificial intelligence in the field of UAV could be implemented in the future, based on an analysis of the current state and direction of research and development in the present. We describe the possibilities of use artificial intelligence systems in two areas that are currently receiving the most attention at concept level, namely the flight of autonomous UAV swarms and the improvement of communication and data exchange between individual UAVs using artificial intelligence.
