description: The aim of the work is the design and calculation of a gas turbine unit with a capacity of 18 MW, the prototype of the NK â 16 â 18ST gas turbine engine is taken as the basis. Calculations of the GTU thermal circuit, calculation of low-and medium-pressure compressors, detailed gas-dynamic calculation of the gas generator turbine and the power turbine in characteristic cross-sections were performed. The calculation of the average diameter and the calculation of the flow twist for the working blade of the power turbine stage is carried out. On the basis of the obtained calculations, a drawing of the longitudinal section of the flow part of the GTU is made. 3D models of the main parts of the power turbine are obtained: the rotor, the disk and the working blade. With their use, strength calculations were performed, the stress and vibration states were analyzed, and materials that meet the reliability condition were selected. The article describes the design of a gas turbine unit and its main components: a compressor, a gas generator turbine and a power turbine, a combustion chamber, supports, bearings, and seals. Methods of protection against GTU surge are given, a method of increasing the efficiency of the installation by injecting water into the combustion chamber and regenerating the heat of the exhaust gases is considered.
