The gas turbine unit GTK-10 was chosen as a prototype. In the course of the work produced: 1) calculation of the thermal scheme, after analyzing the results of which the optimal temperature is selected before entering the high-pressure turbine and the degree of pressure increase in the compressor;2) approximate calculation of the axial compressor, based on the results of which the number of stages in the compressor is assigned;3) calculation of an individual combustion chamber with obtaining the geometric dimensions of the flow part and the characteristics of the working process in it;4) 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;5) 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.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 20.2 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. |
