I've been reading through the 2009 paper and noticed that the simulated Cnalpha quantities are pretty far off of the wind tunnel data referenced. Does anyone know if that part of the aerodynamic model has been improved? If it hasn't, anyone have ideas for how to be confident in the dynamic stability of a rocket short of trying to tie OR into a CFD model or something? It looks like RasAero has a much better Cnalpha prediction, but we haven't been able to find as much detailed information about how the rest of the RasAero simulation operates. My team's funding is somewhat dependent on being able to describe exactly how our simulation works.
Thanks all,
Craig
