The part of the airfoil that decreases airflow is known as what?

The trailing edge of an airfoil is the location where airflow is typically disrupted. This is the rear edge of the wing or airfoil that comes into play as air flows over the surface during flight. As the air moves past the leading edge of the wing, it travels across the cambered surface and ultimately converges at the trailing edge.

At this point, the airflow may become turbulent due to the changes in pressure and velocity as the air is released from the surface of the airfoil. This turbulence can lead to a decrease in effective lift if not properly managed. The design of the trailing edge is crucial in controlling airflow patterns and reducing drag, as it can influence the lift-to-drag ratio of the wing. Understanding how the trailing edge works helps in the aerodynamic design of aircraft for optimal performance.
