As the angle of attack of a symmetrical airfoil increases, what happens to the center of pressure?

For a symmetrical airfoil, the center of pressure is defined as the point at which the total lift force can be considered to act. As the angle of attack increases, particularly for symmetrical airfoils, the behavior of the center of pressure is quite stable compared to cambered airfoils.

When the angle of attack of a symmetrical airfoil is increased, the lift generated does increase, but the center of pressure does not shift significantly along the chord of the airfoil. This is because a symmetrical airfoil produces lift primarily due to its shape and the flow characteristics around it, rather than relying on geometric camber.

In the case of a symmetrical airfoil, as the angle of attack increases, the airfoil's performance changes, but the point where the lift acts remains relatively constant, particularly until significant changes in angle of attack lead to stall conditions. This makes the assumption that the center of pressure remains unaffected a valid interpretation for small to moderate angles of attack in symmetrical airfoils.
