12.4 Performance of the Gas Generator and the Single-Jet Engine
12.4.1 Analysis with Loss-Free Components
The cycle without component losses is sketched in Fig. 12.11. The parts are
0–01:
Inlet
01–02:
Compressor
02–03:
Combustion chamber
03–04:
Turbine
04–4e:
Nozzle (the symbol e denotes
the end of an ideal expansion)
States 0 and 4e are static. The other states are total (stagnation with respect to the
engine frame).
The total parameters of the oncoming air are
