What type of drag results from an airfoil developing lift?

Induced drag is the type of drag that arises when an airfoil generates lift. This phenomenon occurs because of the pressure difference between the upper and lower surfaces of the airfoil, leading to the formation of vortices at the wingtips, which affect the airflow around the wing. As lift increases, so does induced drag, making it directly related to the amount of lift being produced. This is distinct from other types of drag, which are not directly tied to lift generation.

Profile drag, on the other hand, is related to the shape of the airfoil itself and the friction between the airfoil and the air moving over it, while parasite drag encompasses all other forms of drag not associated with lift, including form drag and skin friction. Form drag pertains specifically to the shape of an object moving through a fluid, contributing to the overall resistance experienced but does not directly correlate to the lift produced by an airfoil.
