This paper, the calculation of a gas turbine unit with a capacity of 12 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 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. Analysis of the use of blades with a curved axis and their comparison with radial blades for the last stage of a power turbine. 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 the special part, the analysis of blades with different types of tangential inclination, their influence on the flow and on the efficiency of the gas turbine unit, as well as the relationship between the use of blades with tangential end wall contouring and the efficiency of the turbine stages is established.
