    Analysis of alternative control options fot the ROTAX 915 is engine
    (University of Žilina, 2023) Plochová, Jana; Šajbanová, Kristína
    This article focuses on analyzing the possibilities of alternative management of the ROTAX 915 IS aircraft engine using the ECU MASTER electronic control unit. The article examines how the use of ECU MASTER could become a beneficial alternative to the traditional manufacturer's control system. The new control system would ensure lower costs for purchasing ECU and reduce the number of sensors required to operate the engine. This would achieve a lower weight of the entire system, which is very important for aircraft in terms of fuel efficiency and cost savings.

    Inovácia sústav tubínového motora Safír 5 – palivová a mazacia sústava
    (University of Žilina, 2025) Plochová, Jana; Čerňan, Jozef
    The thesis focuses on the innovation of the fuel and lubrication systems of the Safír 5 turbine engine, which was used as an auxiliary power unit (APU) as a compressed air generator in the L-39 Albatros aircraft. The main objective of the thesis is to analyse the technical possibilities of modifying this engine to change its original purpose, ensure smooth power regulation, simplify start-up, and increase its reliability. The theoretical part provides a detailed analysis of the operation of turbine engines, the principles of the fuel and lubrication systems of the Safír 5 engine, and their importance for the engine's smooth operation. In the practical part, technical modifications of the fuel and lubrication systems are proposed and implemented, including the construction of a new stand, the design of a fuel tank, and the electrical wiring. The functionality of the modified engine was subsequently verified through a series of tests. The result of the work is a functional and reliable Safír 5 engine with improved parameters, which can serve as a teaching aid or as a basis for further experiments.
