Just a heads up; I got messaged (nicely for the record) by a representative of Lockheed today, asking that the AIAA papers be removed for copyright reasons. I can't delete the posts because they're too old / other posts have since been made, but I've contacted the mods, so the documents / links to the non-paywalled versions should be deleted soon.
I imagine anyone reading this already has a copy of all of them, but if someone hasn't manages to read this, the documents will still be available at the links mentioned in this post: viewtopic.php?f=58&t=12237&start=310
If you work for a major aerospace company, or if you attend or work for a university, or if you just have access to a local library, check to see if they have free (legal and licensed) access to AIAA's library.
If not, and if you choose to buy some papers, get a membership if you plan on buying multiple; you'll likely save money (depending on the membership type) as members get decent discounts on papers.
