What is the main purpose of the camber in a wing's design?

The main purpose of the camber in a wing's design is to enhance lift by changing the airflow speed over the wing. Camber refers to the curvature of the wing's airfoil shape. When the wing is designed with a specific camber, it alters the distribution of air pressure around the wing.

As air flows over the wing, the shape and curvature created by the camber cause the air to travel faster over the top surface than it does along the bottom. According to Bernoulli's principle, this difference in airflow speed results in lower pressure on the upper surface and higher pressure on the lower surface, ultimately producing lift.

This aerodynamic feature is critical for maintaining efficient flight, especially during takeoff and landing phases when lift requirements are crucial.
