What is meant by the term "camber" in relation to aviation?

Camber refers to the curvature of the upper surface of an aircraft wing. This curvature plays a crucial role in the aerodynamics of the wing, influencing how air flows over its surface. A wing with a positive camber has a rounded top, which helps to create lift as air moves faster over the curved surface compared to the flatter lower surface. This difference in airflow speed leads to lower pressure on the top of the wing and higher pressure on the bottom, resulting in lift.

In the context of aviation, understanding camber is essential for aircraft design and performance. Different camber profiles can be used to optimize lift characteristics, control stall behavior, and enhance overall aircraft efficiency at various speeds and angles of attack.
