Flying Toy Airfoil Design

mullindm · Jan 28, 2006

Hi;

I am working on a new type of flying toy. Does anyone know any groups or persons that can help with CFD calculations and foil designs, so we can make a prototype?

Thank you for your help.

I don't think you really want/need cfd for this. Reynolds number for toy flight is quite low, so the usual rules do not quite apply. Use something simple, like Clark Y. Cl vs alpha will be normal, but stall will occur at about Cl = 1.0. Cdo will be about 0.015, and will increase with Cl according to the usual rules.
