Газотурбинная установка

Abstract

Тема выпускной квалификационной работы: «Газотурбинная установка». Данная работа посвящена проектированию газотурбинной установки мощностью 16 МВт для привода газоперекачивающего нагнетателя на основе ранее разработанной газотурбинной установки НК-38СТ. В работе произведены расчеты тепловой схемы, приближенный расчет компрессоров низкого и высокого давления (КНД и КВД соответственно), расчет камеры сгорания (КС), подробный газодинамический расчет проточных частей турбин низкого и высокого давления (ТНД и ТВД соответственно), а также силовой турбины (СТ), расчет закрутки потока в последней ступени силовой турбины. На основании проведенных расчетов разработан чертеж продольного разреза газотурбинной установки (ГТУ) а также проведено моделирование элементов последней ступени силовой турбины (лопатка, диск, вал). Выполнен расчет данных элементов на прочность и вибронадежность в программном пакете ANSYS Workbench методом конечно-элементного анализа.

The subject of the graduate of qualification work is «Gas turbine power plant». The given work is devoted to the design of a gas turbine plant with a capacity of 16 MW to drive a gas compressor supercharger based on a previously developed gas turbine plant NK-38ST. This paper presents calculations of the thermal scheme, an approximate calculation of low- and high-pressure compressors (LPC and HPC, respectively), calculation of the combustion chamber (CC), a detailed gas-dynamic calculation of the flow parts of low- and high-pressure turbines (LPP and HPT, respectively), and also power turbine (ST), calculation of flow swirl in the last stage of the power turbine. Based on the calculations, a drawing of a longitudinal section of a gas turbine unit (GTU) was developed, and modeling of the elements of the last stage of a power turbine (blade, disk, rotor) was also carried out. The calculation of these elements for strength and vibration reliability in the software package was performed ANSYS Workbench by finite element analysis.
