> The goal of her work is to develop a method of obtaining the parameters of the airfoil boundary layer from an existing high-fidelity computational fluid dynamics code, without requiring any more effort from the code’s end-user than was required previously, she said.

So the goal is to make this a more generic computer model to avoid the cost of wind-tunnel testing using a fluid dynamics model. I don’t know from the article if any of this has actually unveiled anything - sounds like the goal of the work, which is progressing Ok.

EDIT: Link to the paper. Yours for $30. Ugh. Why is this costing something when I already paid for the research? https://vtol.org/store/product/computation-and-extraction-of...

From 2013 onwards, all (non-classified) work funded by the US government must end up in an open-access repository, either immediately or after a 6 or 12 month embargo period. Here's the policy memo: https://www.science.gov/docs/ostp_public_access_memo_2013.pd...

For this, I'd look in DTIC, though I couldn't find it yet: https://publicaccess.dtic.mil/padf_public/#/home

404 for me. Not sure whether that's because I'm not in the US or because I'm using a mobile browser or whether you messed up the link.

I blame the White House. Updated with a new link.
