The purpose of this work is to design a gas turbine plant with a capacity of 170 MW based on the V94.2 prototype. Tasks that were solved during the work: 1. Calculation of the thermal scheme, based on the results of which the degree of pressure increase in the compressor and the temperature at the turbine inlet are selected; 2. Gas-dynamic calculation of axial compressors; 3. Calculation of the combustion chamber with obtaining its geometric dimensions and environmental characteristics; 4. Gas-dynamic calculation of a turbine; 5. Calculation of the flow twist for the last stage of the turbine; 6. Construction of a three-dimensional model of a working blade and disk of the last stage of turbine; 7. Strength calculation of turbine elements; 8. Calculation of vibration reliability of the rotor shaft and impeller of the last stage of the turbine; 9. Description of the gas turbine plant design; 10. Determination of the efficiency of the "last stage – diffuser" unit; 11. Modernization of the peripheral circumference of the annular diffuser in accordance with the shape of the profile of the power racks in order to increase the efficiency of the "last stage – diffuser" unit.
