The term "airfoil" often conjures images of the wing of an airplane, and indeed, these shapes are critical components of most fixed-wing aircraft. For engineers designing airplanes or aerodynamic models, the NACA Airfoil designation (where 'N' stands for National Advisory Committee for Aeronautics) plays a significant role in specifying the desired characteristics of such shapes. The acronym can be found in the titles of airfoils designated with a number between four and five digits. Here are a few details to get started with learning about this: The first two figures in an NACA airfoil designation tell us that the thickness distribution for that airfoil has been based on tests which resulted in its specific pressure coefficient. This can range from 0.00 up to at least 18.0; therefore, you could end up using 1800 different numbers. The middle figures give information about the angle of attack or slope and this angle can also be known as an angle between chord and wing (usually measured clockwise), but in this particular scenario I am looking for it so called camber line slope with relation to chordline. You're getting ready for the real NACA Airfoil stuff, which begins now. This 3-figure sequence represents thickness or rather percentage thickness along chord. In essence these represent height differences on chord from zero degrees angle at trailing edge to zero degrees at leading edge
