description: The theme of the final qualifying work: "Gas turbine unit with a capacity of 20 MW". The final qualifying work is devoted to the calculation and design of a gas turbine unit with a capacity of 20 MW. The prototype of the projected unit was the GTU-25, which is based on a converted aircraft engine. In the course of the work, the following tasks were performed: â calculation of the thermal scheme of the gas turbine unit; â calculation of an axial compressor; â calculation of the combustion chamber; â gas-dynamic calculation of the turbine; â study of the dynamics and strength of the elements of the last stage of the turbine; â construction of 3Dâmodels of some elements of the last stage of the turbine. â development of a longitudinal section of the engine; â study of converting an aircraft engine for use as a natural gas supercharger drive. As a result of the work, an axial two-stage compressor, an annular combustion chamber, a gas generator turbine and a power turbine were designed. Based on the results of the calculation, a longitudinal section of the engine was developed, the impeller of the last stage of the power turbine was profiled. As a result of calculating the static strength, a material for the rotor blade and disk was selected that meets the strength criterion. The calculation showed that the vibration reliability of the rotor blade and rotor is also ensured.
