Aerodynamic resistance against the motion of an object
Drag curve for a lifting body in steady flight
Parasitic drag, also known as profile drag,[1]: 254 [2]: 256 is a type of aerodynamic drag that acts on any object when the object is moving through a fluid. Parasitic drag is a combination of form drag and skin friction drag.[3][1]: 641–642 [4]: 19 It affects all objects regardless of whether they are capable of generating lift.
Total drag on an aircraft is made up of parasitic drag and lift-induced drag. Parasitic drag is named as such because it is not useful, whereas lift-induced drag is the result of an airfoil generating lift. Parasitic drag comprises all types of drag except lift-induced drag.[5]
