5. Analysis
Parametric cycle analysis is also called design point analysis or on-design analysis because each plotted engine is operating at its so-called design point.
The main objective of parametric cycle analysis is to relate the engine performance parameters (primarily thrust F and thrust specific fuel consumption S)
to design choices (compressor pressure ratio, fan pressure ratio, bypass ratio, etc.),
to design limitations (burner exit temperature, compressor exit pressure, etc.), and
to flight environment (Mach number, ambient temperature, etc.).
