## Main Question or Discussion Point

My question is kind of simple, does the calculus of variations find its way into the design of the shape of an airfoil?

I'm interested in what kind of mathematics gets used in basic airfoil design. I suspect the calculus of variations must be involved, but I know nothing about deriving the shape of a plane wing.
