    Conceptual design of the training aerobatic airplane
    (University of Zilina, 2021) Klein, Vladimír; Škultéty, Filip
    Paper deals with the issue of conceptual design of a training aerobatic aircraft with a tandem arrangement of seats. The first part of the paper is devoted to the historical context of the construction and characteristics of training aerobatic aircraft. The work analyses the current state of training aerobatic aircraft together with the situation of aerobatic aviation in Slovakia. The practical part of the paper discusses the design of a training aerobatic aircraft in the software Rhinocerostogether with the determination of technical and operational parameters and analysis of aerodynamic and stress characteristics

    Design optimization of a compressor stage with counter-rotating rotors
    (University of Zilina, 2021) Šajbanová, Kristína; Čerňan, Jozef
    The paper deals with the design optimization of the compressor stage with counter-rotating rotors, especially in order to create a model which, due to its parameters in real operation, would achieve the maximum possible values of efficiency. The primary goal of this work is to create a design of a compressor stage with counter-rotating rotors from a theoretical point of view. The compressor stage model is created using Inventor modelling software and the subsequent design evaluation and optimization is based on airflow analysis of the compressor stage using Ansys Discovery Live software. The secondary goal is to point out the existence and application of innovative and progressive technology of rapid prototyping in the world of aircraft component production and at the same time to emphasize its benefits in comparison with conventional production techniques applied in the initial stages of aircraft component production.

    VYPRACOVANIE TECHNOLOGICKÝCH POSTUPOV ÚDRŽBY PRE LIETADLO ZLÍN Z 242 L PRE POTREBY LVVC ŽU
    (Žilinská univerzita v Žiline, 2020) Mariňak, Róbert; Braciník, Tomáš
    Aircraft maintenance is nowadays a very demanding and precise job that requires professional and qualified personnel. In order of carrying this job out efficiently, the maintenance staff needs high quality and up to date materials, to use while doing their work. The aim of this bachelor′s thesis is to create material that should guide, unify and facilitate the overall process of maintenance procedures of aircraft type Zlin Z 242 L, which recently became part of the fleet of the Aviation Training and Education Centre of the University of Žilina. In our study, we worked with official materials from ZLIN AIRCRAFT a.s. and together with legal norms and valid regulations we tried to create a basis for the design of the job cards for regular inspections. We were looking for a compromise between the standards and the specific requirements of LVVC ŽU. After a tough examination of all aspects, having an influence on the necessary technological procedures, we came to the final design of the job cards of regular inspections of type A, B and the design of job cards of special inspections. This job cards design should enable professional staff to carry out maintenance work directly and clearly and ensure that they can be checked at each stage of the inspection.
