Compressible aerodynamics calculator in Python

Project description

Latest version LICENSE travis

A python package for compressible flows. A dynamic toolkit which enables you to make use of the formulae governing compressible flows.


  • Python 2.7, >=3.4

  • pylab (numpy, scipy and matplotlib)

  • ashwinvis/scikit-aero >= 0.2

  • PyQt5 / PySide (optional, but recommended for GUI)

  • pandas (optional: for making tables)

  • colorlog (optional: for coloured log)


To install from PyPI:

pip install -e git+

# Any of the following
pip install caeroc
pip install caeroc[pyqt]
pip install caeroc[pyside]

To install development versions of caeroc and scikit-aero

pip install -e git+ --process-dependency-links --trusted-host

If the current configuration of the GUI does not work for you, regenerate it by running:

cd caeroc/gui


Simply run in your terminal



Development mode will install caeroc using soft links.

git clone --recursive
cd caeroc
python develop
cd ../scikit-aero
python develop


  • [x] Command-line tool which opens a Qt based GUI calculator

In development <figcaption>

In development

  • [ ] Save data as a database

  • [ ] Plotting graphs

  • [ ] Generate gas tables

  • [ ] Calculate flow characteristics: Coefficient of pressure, lift and drag for basic profiles.


  • The idea for a compressible aerodynamics calculator in the form an online JS tool had been implemented by William Devenport here. This project is pushing more functionalities as an offline tool and allowing users to dynamically use the formulae for specific cases.

  • Thanks to the scikit-aero team for being the backend
