Anyone knows about the function of atmospheric drag in stock KSP games v.1.0.5 ?

[Lookerksy]

Has someone got the atmospheric drag function from game files, or an approximate function by fitting?

I want to try to simulate flight in mathematical software.

It's necessary.

Thanks.

I'm pretty sure drag is still quadratic. And they probably fixed lift to be quadratic as well. It's the drag and lift coefficients that are computed differently now.

If nobody has decompiled the binaries yet to take a look at how it does these estimates and how it gets occlusion, somebody should.
