I have a couple questions. Accepting the premise that a flat belly pan is suboptimal due to the flow detaching as compared to an airfoil shape, what is the minimum curvature of the airfoil shape required to negate this effect? For example, if we take a vehicle 240” long, what minimum width of airfoil cross section would be required to prevent this effect? Are we talking neighborhood of 1”, 5”, 10”, or 20”?
Second question- when you say “airfoil” are you referring to symmetric or non-symmetric camber? (the teardrop shape or more like the top/bottom of an airplane wing shape) Would this lower airfoil generate lift/down force depending on the camber or lack thereof as compared to a flat shape, and would that introduce drag?
Thank you.
