Dear all CFD Web friends,

Would you please give me a help?

Now I need to get a free or low price CFD or engineering estimate software about micro air vehicle. I don't and needn't deeply research Aerodynamic discipline. But when I research micro air vehicle's control probelm, I must learn the plane's pneumatic parameter, include all compeletly plane pneumatic parameters, such as lift coffient,moment coffient,oprate coffient,and various dynamic differential coefficient. Espicially, I must insert this software compute result into my program, that is to say, when I chang some plane geometry parameters or structure parameters or control scenario, this software must auto recompute pneumatic parameters in order to my program auto redesign.

In addition, I must explain: Micro air vehicle's speed is rather low(<110m/s), its volume is small and its weight is lightly(<=10kg), but its aerodynamic outline might be rather complex.

if you know about some infomation, You can tell me how i get the simple and very valuable software.

thinks.

(1). Look like that you are designing a model airplane. (2). If so, checkout the model airplane companies. (3). Or, you can try to learn the basic aircraft design, try the book on " Aircraft Conceptual Design" by Dan Raymer, or visit "www.aircraftdesign.com" (4). Or it could be a model for the Star Wars type Holywood movies, GPS guided, high resolution, high zoom power camera epuipped, and possible a micro bomb capability? Then try model shops in Holywood.

Dear Fred.

Think you very much!I have look at the web you gived me.but i need the program running on the Pc windows 95/98/nt platform, not system 7.Please give me another information.
