WebOct 9, 2024 · Induced and Parasitic Drag. In aviation, induced drag is a phenomenon where moving objects that redirect airflow (an example being F1 cars’ wings) create aerodynamic drag as a side-effect of generating lift or downforce. In F1 cars, this effect is most apparent at the wings, which are the components that generate the most downforce. WebThe meaning of PARASITE DRAG is the portion of the drag of an airplane that does not include the induced drag of the wings.
