Exactly right, I think Georgia Tech and another university in Maryland, I had and application filled to both of them to do grad study there, but eventually went somewhere else that was 30 years ago, California was more atractive for a young guy.
(Head of R&D at airbus helicopter is from that Maryland Campus)
Georgia Tech has a nice Video about the state of the art in helicopter CFD, check 25 minute mark to start to feel how involved it is and 54+ minute mark to see how messy it is on the tail.
14,000 compute hour per simulation run !!! ouch, cloud computing bill must be hot.
