Heh, fair enough. OK, how about this: if someone can get me reasonable data on a real turbine, I'll do a model for it and check it in such that other engines can use the same interface, even if the numbers are wrong. It doesn't need to be really involved. Basically, what I'd need is stuff like: + What the RPM curve vs. time looks like the as you hold the starter button down. + The temperature curve vs. time, showing the points where control inputs were made. + The handbook procedures that tell me which numbers are important, and which ones I can fake. + The handbook descriptions of what the failure modes are, how they are caused, and (roughly) what the effects are. I don't think anyone cares if we get this exactly right -- it doesn't matter whether the over-temp condition is exactly the same temperature as you would see on a real engine, so long as the temperature is pointing at the red area of the gauge. Maybe just a video of the panel during a successful startup would be sufficient.
