    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.

    Proposal and realisation of a modification to Al-9 engine for installing a free gas turbine
    (University of Žilina, 2023) Supuka, Matej; Čerňan, Jozef
    This paper focuses on the creation of a prototype connection of the AI-9 engine with a free turbine for creation of an experimental turboshaft engine. We go through theoretical knowledge about the issue in which we work on the basis of which we created solutions. We worked with the teaching aids of the Department of Aviation at the airport in Žilina. We prepared these tools for work in the workshop and we made minor adjustments to the engine to make it possible to carry out our work. In our work, we used a procedure called high-fidelity prototyping. This means that we created a digital model on which we applied solutions. We decided to transfer our prototype to the digital environment due to low financial and time costs. We faced several design problems, including the need for a stator, the gap between the guide tunnel and the rotor, or how to connect to other components. We managed to find preliminary solutions for these problems and created a digital prototype of the resulting assembly. Subsequently, we presented the positives of our results and the method of their application in practice.
