Main Combustion Chamber

fullflow.MainCombustionChamber

Main combustion chamber mass-balance node.

MainCombustionChamber represents a lumped combustion chamber whose pressure is solved from steady-state mass conservation. The chamber pressure adjusts such that the total incoming propellant mass flow matches the mass flow leaving through the nozzle.
