I've been writing a jet engine simulator (because why not)

A few things I've got going so far:
- GCS (ground control station): A UI setup that will plot engine controls, thrust, engine speed, EGT (exhaust gas temp), fuel consumption, Fuel flow to thrust ratio
- Engine Model: a simple 1-D turbojet engine model that wraps the steady-state engine, with dynamics for RPM, temp, and response, models: Inlet -> Compressor -> Combustor -> Turbine -> Nozzle
- Simulator: that runs a very simple physics / thermodynamics model
- A simple FADEC (Full Authority Digital Engine Control): which is a fancy PID controller currently, that does the controls for the engine model itself (everything is a pid controller? always has been) 

Anyway, lots to add but now it can run simple 'scenarios' like:
- engine startup and stop
- simulating the engine in a flight

pretty cool

This is seriously impressive! The 1-D turbojet model with dynamics for RPM/temp sounds particularly interesting. Have you considered adding compressor stall modeling or exploring more complex thermodynamic cycles? The FADEC as PID controller approach seems practical - curious how it handles extreme scenarios like rapid throttle changes. Keep us posted on your progress!
