Ambient air is drawn into the compressor, where it is pressurized—a theoretically isentropic process. The compressed air then runs through a combustion chamber, where fuel is burned, heating that air—a constant-pressure process, since the chamber is open to flow in and out. The heated, pressurized air then gives up its energy, expanding through the a turbine(s)—another theoretically isentropic process. Some of the work extracted by the turbine is used to drive the compressor.
