Re: [Flightgear-devel] Aircraft with "old" JSBSim specs in base package
I'll look into it, maybe i can make those plots for you using a vortex panel method on the profile of the airfoil. I'll keep you posted. Julien

I don't consider it a real high priority because there a is a pretty good YASim config in existence. It would be nice though to have a YASim and JSBSim version of the plane.

Josh what kind of data would you like to obtain from those profiles? Julien

They are the airfoil cross sections. (I actually used them to make the .ac model) I know that you can get polar data from them, I just don't think that it will realistically ever get done. I might be wrong, but hey. I originally considered doing some CFD on them, but I could not find any linux program that I could grok to do this (I never got x-foil to work right) and I didn't want to install windows just to run some of the easier software.

There is a specific Boeing airfoil used in the B-29 and it's variants, i think it's the 319. Anyway, there doesn't seem to be any freely available data on it, much like all Boeing airfoils.
