I'm playing devil's advocate a bit, but ... what if there is no such 
library that would give you the values you need regarding lift, etc. 
What if part of what you need to do in the simulation is to create these 
calculations? Then you must certainly know these arcane formulae.

Granted, if something is needed enough, you won't be the first person to 
do it and a solution will be available...
