Abstract
An aircraft or aircraft body having an airframe structure, a pylon, a protrusion, and a nacelle. The airframe structure is a wing or a fuselage. The pylon has a first end, a second end opposite the first end, a first surface extending between the first end and the second end, and a second surface opposite the first surface. The first end is fixed to the airframe structure. The protrusion extends outward from the first surface and/or the second surface. The nacelle is located at the second end of the pylon and has a leading end, a trailing end, and a tapered boattail at the trailing end. The protrusion is located between the airframe structure and the tapered boattail. The protrusion is sized, shaped, and positioned between the boattail and the fuselage or wing to mitigate boundary layer separation.
