Aerodynamics

The airflow physics that shape how a multirotor behaves: rotor downwash and propwash on dive exits, and how a duct changes efficiency and handling.

• Ducted Fans — Airflow, Efficiency, and Trade-offs
  A duct (shroud) around a propeller changes how air enters and exits the disk — …
• Propwash — Reversed Inflow, Blade Stall, and Dynamic Idle
  A propeller is a spinning wing, and like any wing it only makes clean thrust …
