For coordinates that are not smooth, the NASA AFSMO smoothing code (airfoil smoothing code) can be used to smooth the points.The original airfoils/coordinates do not, e.g. The coordinates give smooth inviscid velocity distributions, but some of Von Doenhoff) courtesy of Ralph Carmichael, PDAS: Corrected NACA coordinates from Theory of Airfoil Sections (Abbott and.NACA Report 93 (1921) includes coordinates and wind tunnel data on.Model airplane site, mostly focused on flying wings:.Martin Hepperle's site, including airfoil coordinates (mostly listed here as well) and lots.The TraCFoil website has many airfoils that are not included below.

The spreadsheet also gives the spar heights needed, assuming that each spar is placed at the corresponding crease location and is oriented vertically. Again, these can be imported to other software as in the previous case. The user can also specify a chord length to generate a second set of coordinates that describe the airfoil at that chord length. These points can also be imported to software such as SolidWorks for modeling a wing. It generates a list of 100 points that can be imported into flow simulation software such as XFLR5 or ANSYS Fluent for analysis of lift/drag properties. I had been looking for an easy way to create an airfoil shape with foam board, and that fit the bill! I wanted to create other airfoils using a similar technique, so I created a spreadsheet that generates a flat bottom airfoil with creases on the top edge as specified by the user. Spars/spacers were inserted to keep the airfoil shape. A while ago I built the FT Bloody Wonder and loved how the airfoil was created: a flat bottom with creases along the top edge to approximate the profile of a curved-top airfoil.
