The basic operation o the gas turbine is the Brayton cycle wi air as the wirkin fluid. Fresh atmospheric air flows throu the compressor that brings it tae higher pressure. Fuel is then sprayed intae the air, an ignited, sae the combustion generates a heich-temperature flow. This heich-temperature heich-pressure gas enters a turbine, whaur it expands doun tae the exhaust pressure. The turbine drives a shaft which drives the compressor an the load, sic as an electric generator. In jet engines, the energy that is nae uised tae drive the compressor produces thrust tae power the aircraft forwards. The fowert step o the Brayton cycle (cooling o the wirkin fluid) is omeetit, as gas turbines are open seestems that dae nae uise the same air again.
Gas turbines are uised tae power aircraft, trains, ships, electric generators, pumps, gas compressors an tanks.
