Wing Aerodynamic Devices and Features ✈️
1. Vortex Generators:
Function: Small surfaces that create vortices.
Purpose: Energize airflow, delaying boundary layer separation and improving control at low speeds.
2. Notched Leading Edge:
Function: A notch on the wing’s leading edge.
Purpose: Helps delay stall and improve lift by redirecting airflow at high angles of attack.
3. Dogtooth Leading Edge:
Function: A serrated section on the leading edge.
Purpose: Generates vortices for stable airflow, enhancing performance in high-speed maneuvers and reducing flow separation.
4. Boundary Layer Fence:
Function: A vertical barrier on the wing.
Purpose: Prevents spanwise boundary layer flow, keeping airflow attached to the wing for better control and less drag.
5. Vortilon (Underwing Fence):
a) Vortilon:
Function: Small surface under the wing.
Purpose: Creates vortices, reducing stall and improving lift at high angles of attack.
b) Pylon:
Function: Support structure under the wing.
Purpose: Helps manage airflow and provides stability, often used to mount engines or equipment.
