Gas turbine

OverviewTheory of operationTimeline of developmentTypesExternal combustionIn surface vehiclesMarine applicationsAdvances in technology

In an ideal gas turbine, gases undergo four thermodynamic processes: an isentropic compression, an isobaric (constant pressure) combustion, an isentropic expansion and isobaric heat rejection. Together, these make up the Brayton cycle, also known as the "constant pressure cycle". It is distinguished from the Otto cycle, in that all the processes (compression, ignition combustion, exhau…
