Hi,
It's pretty easy to enable, but I will warn it takes much longer to solve than a typical SUAVE case. So I would just use a cruise segment for experimentation.
Here's the options you need to enable in the aerodynamics analyses:
aerodynamics.settings.use_surrogate = False
aerodynamics.settings.propeller_wake_model = True
You'll also find more accurate results if you enable Fidelity One wake methods for the rotor when you setup the vehicle.
from SUAVE.Analyses.Propulsion.Rotor_Wake_Fidelity_One import Rotor_Wake_Fidelity_One
rotor.Wake = Rotor_Wake_Fidelity_One()
Remember to set the rotation direction as that does changed the results:
rotor.rotation = 1 #(clockwise from behind) or -1 (ccw from behind)
Let us know if you have any questions.
