What results from having a greater curve on the top surface of an airfoil compared to the bottom?

When an airfoil has a greater curvature on its upper surface compared to its lower surface, it typically results in increased lift. This aerodynamic principle is rooted in Bernoulli's principle, which states that as the speed of a fluid increases, its pressure decreases.

As the airfoil moves through the air, the greater curvature on the top surface causes the air above the wing to travel faster than the air below the wing. This difference in airflow speed leads to a decrease in pressure above the wing compared to the pressure below. The higher pressure beneath the airfoil pushes up against it, resulting in an upward lift force.

This lift generation is essential for flight, particularly during takeoff and landing, as well as for maneuvering in the air. In contrast, decreased lift, improved stability, and increased speed do not directly result from having a greater curve on the top surface of an airfoil. Instead, the curvature directly facilitates the aerodynamic conditions necessary for lift to occur.
