A drag-reducing structure is provided on a pylon that suspends a wing-mounted engine. The structure reduces drag by preventing ambient airflow, in a region between the wing, pylon, and engine, from accelerating to supersonic velocities and causing shock waves resulting in excessive drag. In one embodiment, the structure is a broad fairing on the inboard vertical surface of the pylon. In another embodiment, the structure is a tapered bump mounted at the inboard intersection between the wing and pylon. |
