4. A regenerative two-stage gas turbine with reheat operating on
the standard-air Brayton cycle is illustrated in Figure 3. In an
ideal Brayton cycle, the processes in the turbines and compressor
are adiabatic and isentropic, and the air flows through the
combustor and heat exchangers at constant pressure.
