Free Fluid CAD

Is there a freely available CAD that I could use to design a wing that will generate a specified force (perpendicular to the incoming air stream) with an optimal shape and size?

If not, would anybody care to point me in the direction of the math I'd need to do it manually?

Thanks. It would also be helpful to know the exact shape of the cross section so I could build it myself.
 
Given that you are asking for a professional level program, I would seriously doubt that you will find one free.

I used to knock around with some free CAD programs (google for them) and they weren't impressive.

Then I got Autodesk Inventor 7 Pro (includes mechanical desktop and autocad 2004) for free through my school's robotics program and have been happy. I don't know very much about autocad and mechanical desktop (i spent most my time in inventor) so I don't know if they do fluid mechanics. Mechanical desktop might do it, but I don't know.

Edit: You can probably get some time on a cool program through a university or something. Maybe your office has a seat or two you can borrow . . . .

Ask around, I doubt you will find a freeware one.
 
Well, I'm a geek. I should make one once I learn what's involved and post it on sourceforge or something.

Edit: First, I need to learn all I can about fluid mechanics. That's my essential problem now.
