pyBEMT is an implementation of the Blade Element Momentum Theory in Python. The model can be used to estimate the thrust generated by a propeller or the power generated by a turbine.

Notable features:

  • A small and unified implementation for both propellers and turbines

  • A model for coaxial rotors

  • Optimization of rotor parameters
