interference drag


interference drag
Drag caused by flow interference at the wing/fuselage, wing/nacelle, and other such junctions. This interference leads to the modification of boundary layers and creates a greater pressure difference between the fore-and-aft areas on the surfaces concerned. This, in turn, leads to greater total drag. Fairings or additional fillets are used to streamline these intersections and decrease interference drag.
