the open source parametric airfoil generator

About

ParaFoil is a declarative tool that parametrically generates turbomachinery and aircraft airfoils and passages with B-splines. The purpose is to generate airfoil shapes from different parameters during fluid simulation optimizations.

Example

Airfoil

import numpy as np
from parafoil import CamberThicknessAirfoil

airfoil = CamberThicknessAirfoil(
    inlet_angle=np.radians(40.0),
    outlet_angle=np.radians(-20.0),
    stagger_angle=np.radians(0.0),
    upper_thick_prop=[0.035, 0.14, 0.14, 0.035, 0.007],
    lower_thick_prop=[0.035, 0.14, 0.14, 0.035, 0.007],
    leading_prop=0.5,
    trailing_prop=0.5,
    chord_length=1
)

airfoil.visualize(include_camber_ctrl_pnts=True)

Passage

from parafoil import TurboRowPassage 

passage = TurboRowPassage(
    airfoil=airfoil,
    spacing_to_chord=1.0,
    leading_edge_gap_to_chord=0.25,
    trailing_edge_gap_to_chord=0.25,
)
passage.visualize()
