[0002] A gas turbine is an internal combustion power machine that converts the energy of fuel into useful work. It is a rotary impeller heat engine. Its basic principle is to pressurize air through a compressor and then pass it into a combustion chamber, where the fuel burns to produce high-temperature combustion gas. Gas turbines play a very important role and are widely used in industry and transportation. Due to the large size and weight of gas turbine equipment, they are generally assembled in sections.
