RE: [Jsbsim-devel] Airfoils at high alpha

[Bill G. <bi...@ao...>]

Yeah, I knew that you'd bring that up. Okay, EXCEPT for that =
aircraft....
What is your return on your investment?  Would those efforts be better =
spent
somewhere else, such as adding helicopters to your modeling...   (Oooo,
sounds like a challenge from the new kid on the block!)

It's Pugachev's Cobra, and it goes to 120 degrees. With fly-by-wire =
aircraft
that are neutrally or negatively stable, and where the FLCS can have =
pitch
limits overridden, modeling high alpha becomes important.

One can also ask the question, what can we do better?
