    Digitalization of the maintenance process for the needs of the CAO organization
    (University of Zilina, 2022) Mariňák, Róbert; Braciník, Tomáš
    Digitalization and automation are unstoppable processes that are linked to the present and have a significant impact on the efficiency of the work carried out in aviation or any other industry. The aim of this article is to create a digital maintenance environment for the needs of the Combined Airworthiness organisation (CAO), which is part of the Air Training and Education Centre of the University of Žilina. Such software would unify and facilitate the overall maintenance process performed by the CAO. In this article we have evaluate the requirements of the CAO organisation and the legislation in force. During the development process, we communicated extensively with both the experts and the maintenance staff for whom we were developing the program. Then, based on what we learned, we created a basic structure of the required software and hardware needed to create a digital maintenance environment and started building it. We have then described all the processes involved in the program and its components to the extent that this article can partially serve as a guide for the creation of such a program. Methods of drawing on software and hardware resources have been purposely limited in the article to free products or to those, that are commonly available in price. The work has resulted in functional software that contains all the necessary documents, job cards and forms to carry out maintenance and substantially replaces the more paper-intensive form of data entry and storage.

    Methods of implementation PIV system in the wind tunnel of the department of air transport
    (University of Zilina, 2022) Remiaš, Matej; Pecho, Pavol
    In the early days of aviation, wind tunnels were developed to investigate whether an aircraft is capable of flying, and how capable it was of doing so.They are mainly used as a part of research of aerodynamic forces applied to a model of an aircraft or its parts. There are several methods of measuring the airflow inside a wind tunnel, however this manuscript is concerned with implementation of Particle Image Velocimetry (PIV), especially the software part, in the conditions of the wind tunnel of the Department of Air Transport. The functions of the software were investigated on the basis of a simple experiment. The poppy seeds were blown on white paper and the images were captured by the camera in slow motion as it moved from side to side and then the images were processed and analyzed. The amount of poppy seeds used varied.The results showed successful use of PIV software and it’s application directly in the wind tunnel of the Department of Aviation for research of the effects of aerodynamic forces in aviation, but also in other areas.

    Electronization of a modern flight school
    (University of Zilina, 2021) Dvorščák, Dávid; Novák, Andrej
    This paper deals with the selection of a specific solution for the electronic management system of the Aviation Training and Educational Center of the University of Žilina in Žilina. The selection is based on an analysis of system properties and research using a pair of questionnaires in which we found out the preferences of instructors and students in flight training. We identified the basic functions and components of the systems and compared them with the research findings. We fulfilled the basic goal of this paper by selecting three systems, that meet the requirements of students, instructors and flight school. The introduction of one of these systems would simplify flight training for students in the future and increase the overall efficiency of the flight school.
