Modelling and Simulation of the Bipropellant Feedsystem and Engine. Use for tuning the operating point of the engine, sizing components and active controller design
For initial testing of the solver, a simplified network representing the engine and plumbing system is used (see below)

| 2 | Ox Tank Ullage |
| 3 | Fuel in Tank |
| 4 | Ox in Tank |
| 5 | Regulator Downstream |
| 6 | Combustion Chamber |
| 7 | Nozzle Exit |
