Design a turbine blade profile within FreeCAD
You always start from an existing design. Then you just have to modify it. You can start from the original design nested in Beltrami or load an example that comes close to your goal.
A user manual can be found online
Note: All the documentation has been generated in French. However, your web browser translator works very well. MS Edge seems to have the best friendly translator.
