    Koncept vrtuľového propulzora pre široký rozsah rýchlosti letu
    (University of Žilina, 2024) Ivan, Jakub; Čerňan, Jozef
    This thesis is focused on creation of propeller concept for wide range of flight speed. The part, which is discussed in the thesis is creation of design for blade motion mechanization, that can reach variable diameters. Apart of creation of this design, the thesis offers historic overview of propeller development throughout the years. Mechanization is designed in 3D environment. The software used for design is Autodesk Inventor. Design isn´t calculated of given engine. The outcome of this thesis is to give perspective for constructers, whoever would want to construct this idea in reality, not 3D environment only. The design in 3D environment is working as it should and when motion is launched, blades are really changing the diameter. In the design study, radius difference between extended and reduced blades is more than 300 millimeters. Desing complies with the task.

    Návrh hybridnej pohonnej jednotky pre experimentálny letún Straton D7
    (University of Žilina, 2024) Longauer, Oliver; Čerňan, Jozef
    The aim of this article is designing hybrid power unit for the needs of experimental aircraft Straton D7. Article describes different options of hybridization of power units on basis of their architecture and the function of electric component in relation to the whole power unit. Compares different designs of automotive and aircraft solutions of hybridization of power units. After that, article offers solution for hybrid engine of Straton D7 on basis of gained theoretical knowledge, comparison of shown conceptions and basic calculations, with the needs and predispostion of the original aircraft in its best interest.
