RE: [Flightgear-devel] Concorde
This ought to be easy (haven't I said that before?). If no one else gets to it, I'll give it a shot after the kids get to sleep - if _I_ am still awake... Which version of JSBSim do you have now? It makes a difference. Look in FGJSBBase.cpp at top to see.

It might be interesting to hav ea fly-off . :-) Does JSBsim handle lift generated by a vortex or a delta wing at low speeds - and does it handle the ground effect of deflected air? Giles Robertson It's all coefficient-based, so if you have (or can get or determine) the relevant aero coefficients, the answer is, yes. Note that we now have a version of Digital DATCOM (Which Bill Galbraith calls DATCOM+) that puts out aero coefficient tables in JSBSim format. So perhaps I could try to set up a DATCOM input file that represents the Concorde. That would be another way to get some pretty good estimates. I'm also trying to find a research paper featuring an SST so that we can get some good sanity-checking coefficients to compare against.

Unfortunately, we can't do tailless a/c in YASim and capturing the ogival planeform would be tricky too so it's probably better handled by JSBSim/uiuc.
