The thermodynamic cycle of the gas turbine 1000 according to the first embodiment may ideally follow the Brayton cycle. The Brayton cycle can be composed of four processes leading to isentropic compression (adiabatic compression), static pressure rapid heat, isentropic expansion (adiabatic expansion), and static pressure dissipation. That is, after sucking in air from the atmosphere, compressing it to a high pressure, burning fuel in a static pressure environment to release heat energy, expanding this high-temperature combustion gas to convert it into kinetic energy, and then releasing the exhaust gas containing the remaining energy into the atmosphere can That is, the cycle can be made in four processes of compression, heating, expansion, and heat dissipation.
