description: Topic of the final qualifying work: Â«Gas turbine unit with a capacity of 25 MW to drive a natural gas blower at the compressor station of the offshore section of the gas pipelineÂ». The aim of this work is to design a gas turbine plant with a capacity of 25 MW. The gas turbine unit GTU-25 was chosen as a prototype. In the course of the work produced: -Â analysis and justification of the need to use a gas turbine unit with a capacity of 25 MW at the compressor station of the offshore section of the gas pipeline; -Â calculation of the thermal scheme, on the basis of the results of which the optimal degree of pressure increase in the compressor is selected; -Â an approximate calculation of the low-pressure compressor and high-pressure compressor, based on the results of which the number of stages in the high-pressure and high-pressure compressor is assigned; -Â calculation of the combustion chamber with obtaining its geometric dimensions; -Â a detailed gas-dynamic calculation of the flow section of the high-pressure turbine, the low-pressure turbine and the power turbine in order to obtain the geometrical dimensions of the flow-through part; -Â calculation of the flow swirling in the last stage of FT, on the basis of the results of which the velocity triangles of the considered stage are constructed and the blade is simulated; -Â analysis of the creep phenomenon, the course of creep deformation processes, methods for minimizing creep on the impeller and methods for calculating creep deformations in Ansys Workbench. Based on the above, a drawing of a longitudinal section of a gas turbine plant, as well as rotor elements of the last stage of the FT, is being developed. Calculation of the strength of these elements in the software package ANSYS Workbench 20.1 is carried out in order to check the vibration reliability of these elements with the subsequent choice of materials. According to the results of calculations the corresponding diagrams are constructed.
