Well... and naming the eq. that you use is that so much classified that you can't even do it?

There is no single equation behind it and it's not a FEM program if that is what you mean. The C++ code is an extension of the code I wrote for my masters thesis (In Simula!) which was to access the influence of external stores like missiles etc on the performance of jet fighters. This meant I had to convert it to C++ and add some functions to handle prop performance and ram effect on engine. The prop function is dependant not only on advance ratio and density effects but also includes Mach effects due to prop tip speed. The same goes for the drag which rises steeply at typical dive Mach like 0.7 and upwards. Not much use in simulating dive performance otherwize. This shortcoming not to model compressibility effects is a major flaw in both IL2 and CloD IMHO.
