Accurately modelling propulsion systems forces and moments is of paramount importance for both design and control of aerial vehicles. With the increasing interest on hybrid vertical takeoff and landing UAVs, methods for propellers forces and moments calculation must be reliable throughout the entire flight envelope, including high incidence angles. In this work we evaluate six different existing methodologies for propeller thrust calculation in two different ways: wind tunnel tests are conducted to evaluate numerical differences, and we also use closed loop dynamical simulations in order to compare the obtained control commands, allowing for an estimation of the impact of such differences in a simulated flight. The methodologies are also compared with respect to applicability considering different steps of the design process. We obtained similar results for all methodologies as they show an offset but yet good prediction capabilities for high incidence angles.
