What does a heavy curvature of a wing indicate?

A heavy curvature of a wing indicates high camber. Camber refers to the curvature of the wing's airfoil shape, which significantly influences aerodynamic performance. A wing with high camber has a pronounced curve that enhances lift at lower speeds, making it particularly effective for aircraft designed for takeoff and landing scenarios.

This characteristic is essential for certain aircraft, such as those that require short takeoff distances or greater lift capabilities in low-speed conditions. High camber wings typically result in an increased pressure difference between the upper and lower surfaces of the wing, thereby generating more lift.

In contrast, low camber wings have a flatter profile, neutral camber wings have a balanced contour that does not favor lift generation as effectively, and negative camber would have a curve that decreases lift, often used in specific maneuvers or configurations. Understanding camber is crucial in aerodynamics and aircraft design, influencing performance variables like stall speed and handling characteristics.
