This Python module provides core functions and scripts to create useful airfoil models and files from engineering specifications. These base models can then be used to create useful designs and implementations (VR and 3D models, 3D printer components, etc).
Wing selection and design can be very complex. From the choice of starting airfoil specs (custom or existing), to cost analysis, and finally to construction, the spectrum of both choices and pitfalls at each stage can become overwhelming pretty quickly, especially to someone whose primary interest is what comes after the wings are bolted on.
The goal behind this software is very straightforward: To give everyone, from the basic hobbyist to the serious (semi)professional, the ability to go quickly from theory and specs to design to real- or virtual-world production of airfoils and wings.
$ pip install wingwalkerExamples of performing various operations are included in the examples directory. Each example is a self-contained demonstration of that feature, from reading the input specification to generating the targe or displaying the products.
The process too generate an STL file for processing or sending to a 3D printer is very simple. This script, located in the examples directory, shows the entire process.
In this example, the requirements for the wing STL file are stored in elliptical_left_wing_256mm.json. This python script
parses the request, parses the designated airfoil specs, and then steps through the process to generate an elliptical wing
of the given dimensions.
