Martincová, AlexandraČerňan, Jozef2024-11-192024https://drepo.uniza.sk/handle/hdluniza/1170The thesis deals with the calculation and optimization of the stage of the gas turbine distributor vanes of an experimental engine. The aim is to create an experimental turboshaft engine by combination of the Saphir 5 auxiliary power unit and a free gas turbine with a gearbox, derived from the TS-21 turbine starter. Through calculations, it is necessary to determine the optimal geometric parameters and the resulting number of stator vanes in order to design a 3D model of the gas turbine stator shroud as a connecting element between the Saphir 5 and the free gas turbine, which consists only of the rotor blades. The results of the work and the evaluation consists of calculations of the thermodynamic circulation of Saphir 5 and calculations of gas turbines. It also contains the design of the stator ring of a free gas turbine, as an intermediate member or flange of two aggregates creating an experimental engine. The 3D model and optimization is created using the Creo 7.0 program, which are based on the calculation of the gas turbine itself. In the end, we will get to the answers and to the summary of the results that created the exact design of the experimental engine.othergas turbinefree gas turbine with gearboxauxiliary power unitturboshaft engineAPU Saphir 5Working Paperhttps://doi.org/10.26552/pas.Z.2024.2.2
