Edit the example script again, this time setting SmoothingPasses to 1. Delete the geometry (you could use the SelAll command to select all objects and then press Delete).Ħ. These fluctuations are not visible to the naked eye, but the curvature analysis tool lays them bare.ĥ.
This is an interpolating curve, i.e., it goes through all the data and, as a result of small numerical errors and the difference between the analytical formulation of the NACA 4-digit foil and the spline we fitted here, the spline snakes significantly between the points. It should look something like this (adjust the density and the scale if needed): Use Rhino’s Curvature Analysis tool (you’ll find it in the ‘Analyze’ menu) to generate a porcupine plot of the curvature of the airfoil curve you have just fitted. AirCONICS has a routine for generating 4-digit NACA airfoils analytically, but for the purposes of this experiment this slightly noisy legacy dataset is ideal.Ģ. Set the value of AirfoilSeligName to 'naca2408'. In fact, it is worth sticking with airfoil_example_SeligCoord.py for a simple experiment.ġ. The goal here is to consider some issues around fitting a curve to legacy airfoil data. Once you have checked that your installation works correctly (i.e., you were able to run airfoil_example_SeligCoord.py), you can start conducting experiments similar to that shown in Figure 5.4.

The first step here is to download AirCONICS, if you haven’t done so already.

This is a good place to start experimenting with building some airfoil geometries based on legacy data and here we offer two ways to do this: via the AirCONICS tool set in Rhino/Python and via the Matlab code included here (scroll down for a first set of airfoil experiments with the latter). Lissaman’s thoughts quoted above, several chapters of the book are dedicated to airfoil geometry description, the first of which is Chapter 5, which discusses some of the fundamentals of designing and using airfoil geometries.
