OpenProp is free software for the design and analysis of marine propellers and horizontal-axis turbines. This software is coded as a suite of MATLAB m-files, so it does require MATLAB. OpenProp can be run using a simple graphical user interface, via the MATLAB command line, or with a user-created script.
As of 2012, the OpenProp project has moved from MIT to Dartmouth College. The legacy OpenProp URL (http://openprop.mit.edu) now redirects to this webpage.
The current version can be downloaded here: OpenProp v3.3.4
