Obtained abilities: The students remember basic concepts and definitions from the thermodynamic, theory and design of the gas turbines and turbo-compressors. The students describe proceeding of the thermal cycle turbo-compressor calculation, the radial compressor calculation, the multi stages axial compressor calculation and the one stage gas turbine calculation. The students learn the radial compressor thermodynamic calculation, the multi stages ax-ial compressor calculation and the one stage gas turbine calculation. The students explain the processes during compressor stall. The students characterize the basic method of the thermal, thermo-mechanical and me-chanical strain of the parts compressors, combustion chambers and gas turbines. The students briefly characterize the attributes of the gas turbines in the role energetic in-stallation and combined steam-gas cycle.
