Flying an unmanned aircraft is therefore based on a number of aerodynamic principles as described earlier in the chapter. However, there are also risks in aerodynamics. For the unmanned aircraft with rotors, there are two potential risks.
Downwash
The downward deflection of air that occurs after a wing profile has broken through the undisturbed airflow is also called downwash.
Ground effect
Vortex
