*Airfoils* is a small *Python* library for object-oriented airfoil modelling. The library provides tools to easily instantiate airfoil objects and to query geometric information. An airfoil object is defined by upper and a lower surface coordinates.

Features
--------

* Airfoil generation with a *NACA-4* series definition

* Import from files

    * Full support for airfoils from the `UIUC Airfoil Coordinates Database <https://m-selig.ae.illinois.edu/ads/coord_database.html>`_

* Interpolation or computation of airfoil geometry parameters

    * Upper and lower surface coordinates
    * Camber line coordinates
    * Chord line coordinates (TODO)
    * Thickness distribution (TODO)
    * Maximum thickness (TODO)

* Linear interpolation between two different airfoils (*MorphAirfoil*)

* Plotting of airfoils

Example
-------

.. code:: python

    >>> from airfoils import Airfoil
    >>> foil = Airfoil.NACA4('4812')
    >>> foil.plot()
