feedtwin.engine.chamber.ConstantCStar Class Reference

Public Member Functions
CombustionState	combustion (self, float pressure, float mixture_ratio)

Static Public Attributes
float	temperature = 0.0
float	gamma = 0.0
float	thrust_coefficient = 0.0

Detailed Description

One number, honestly labelled.

Right for a first pass and for testing the coupling itself, and wrong for
anything that cares about mixture-ratio drift -- with a constant ``c*`` the
O/F trace still moves but nothing downstream of it does, which reads as
"O/F drift does not matter here" when it means "this model cannot see it".
