A modern airfoil is designed on the basis of the desired pressure distribution over the chord length of both sides. In some cases, only a single angle of attack is relevant while in others the airfoil must be a compromise of the pressure distributions over a range of angles and flap deflections. Two parameters can be used to tailor the desired pressure ...

There are lots of answers on this site regarding "how is lift produced" etc. but this post asks about the determination of a typical wing profile, so it might be appropriate to follow through on that aspect. Determine the chord (length from wing leading edge to the trailing edge). Decide on your camber line, for a flat bottom surface wing, this is the ...
