This repo is alright, needs improvement, sys.path should not be used to run modules ect.

The aerofoil folder contains code to design aerofoils with bezier curves.

The Surface class takes the control nodes of the bezier and two surfaces are used to create the pressure and suction surfaces of an aerofoil.

The aerofoil class takes two surface classes and has the capability of plotting and writing to a file for Xfoil importing. An additional static method develop_aerofoil provides inputs to design an aerofoil with control points constrained.

main.py is a file that runs a simple plotting example

import os

import matplotlib.pyplot as plt

from aerofoil import *


# create an aerofoil class from the nodes
aerofoil = Aerofoil.develop_aerofoil(0.1, -0.1, 0.2, 0.5, 0.)

# create a file path to write the coordinates of the aerofoil to
dir_name = os.path.dirname(os.path.abspath(__file__))
file_name = os.path.join(dir_name, "aerofoil.txt")

# write to coords to file
with open(file_name, "w") as open_file:
    aerofoil.write(open_file)

# plot aerofoil
plot = aerofoil.plot()
plot.axis("equal")
plt.show()
