Library for working with C81 airfoil data
Project description
c81utils
A Python module for working with C81 airfoil tables.
Usage
c81utils implements a C81 class that handles the C81 data for each airfoil. A few example usages are shown below:
import c81utils
import numpy as np # Works with numpy arrays too
# Use 'load' to obtain data from a C81 formatted text file
with open("NACA0012.C81", "r") as f:
naca0012 = c81utils.load(f)
# Use the 'get' commands to obtain bilinearly interpolated data
desiredAlpha = 5.0 # in degrees
desiredMach = 0.3
desiredCL = naca0012.getCL(desiredAlpha, desiredMach)
desiredCD = naca0012.getCD(desiredAlpha, desiredMach)
desiredCM = naca0012.getCM(desiredAlpha, desiredMach)
# Combine 'get' commands with the 'map' command to operate on lists
desiredAlpha = np.linspace(0, 10, 6)
desiredMach = [0.0, 0.1, 0.0, 0.3, 0.5, 0.8]
desiredCL = list(map(naca0012.getCL, desiredAlpha, desiredMach))
# Data may also be input using arrays
alpha = [0, 2, 4, 6]
mach = [0.0, 0.5, 1.0]
Cx = [[0.0, 0.0, 0.0],
[0.2, 0.2, 0.2],
[0.4, 0.4, 0.4],
[0.6, 0.6, 0.6]]
CL, CD, CM = Cx, Cx, Cx
myAirfoil = c81utils.C81('myAirfoil', \
alpha, mach, CL, \
alpha, mach, CD, \
alpha, mach, CM)
Installation
c81utils is written in Python 3. Use pip to install.
pip3 install c81utils
1.0.0 (2020-04-25)
Initial release.
1.0.4 (2021-07-21)
Ensure mach and alpha arrays are strictly increasing.
