About this document

Understanding NACA Airfoil Series by thomastan02 is a document available to read on EtoBox.

Five-digit NACA airfoils use a parabolic curve and straight line to define their camber, with digits indicating maximum camber percentage, position along the chord, and thickness ratio. For example, a NACA 23012 airfoil has 15% maximum thickness at 30% chord. The 6-series NACA airfoils were designed to maintain laminar flow over more of the chord for lower drag, identified with five digits like NACA 633-218.
