Subject of the graduate qualification work: "6,3 MW gas turbine" This paper, the calculation of a gas turbine unit with a capacity of 6,3 MW is carried out. The GTU is based on the NK-12 ST engine. To achieve these goals, the following calculations and studies were carried out: 1) Calculation of the thermal circuit with hands and using the a2gtp program; 2) Calculation of the flow part of the compressor turbine (TC) and power turbine (ST); 3) Calculation of the flow twist in the last stage; 4) Strength calculations of the last stage of the turbine; 5) Briefly described the general concepts of the main elements and nodes of the prototype NK-12 ST; 6) Design of a cooled turbine rotor blade. As a result of thermal calculation, optimal parameters for the turbine and compressor were obtained. The result of gas-dynamic calculation is the parameters used to build a 3D model of the blade of the last stage of the turbine. The result of the strength analysis is the determination of the safety factor of the blade and disk, as well as the frequency analysis of the rotor and blade of the last stage of the turbine. In a special part, a study of the working cooled blade of a gas turbine plant was carried out, a model of this blade was constructed and the results of its study in the Ansys program were presented.
