AirfoilDefinitions.jl

AirfoilDefinitions.jl is a Julia package for generating two-dimensional, chord-normalized airfoil geometries using parametric airfoil definitions.

It supports the following parameterization methods:

The following methods are planned:

BezierCurves
HicksHenne
NACA5
NACA6
PARSEC

Install

AirfoilDefinitions.jl is not yet a registered Julia package. So to install it,

Download Julia version 1.10 or later.
Launch Julia and type

julia> import Pkg
julia> Pkg.add("https://github.com/gabrielbdsantos/AirfoilDefinitions.jl")

Quick start

using AirfoilDefinitions

# Step 1. Select an airfoil generation method.
airfoil = NACA4("0012"; open_trailing_edge = true)

# Step 2. Generate the coordinates
coords = coordinates(airfoil)

Coordinate convention

All airfoils are defined in a two-dimensional Cartesian coordinate system with the following conventions:

Chord length is normalized to unity.
The leading edge is located at x = 0, and the trailing edge at x = 1.
Airfoil surface coordinates are ordered clockwise, starting from the upper trailing edge.
