ABSTRACT:
A "compression" pylon 10 for an aircraft with a wing-mounted engine, that does not cause supersonic airflow to occur within the fuselage-wing-pylon-nacelle channel 20. The chord length of the pylon 10 is greater than the local chord length of the wing 12 to which it is attached. The maximum thickness 45 of the pylon 10 occurs at a point corresponding to the local trailing edge 32 of the wing 12. As a result, the airflow through the channel 20 never reaches supersonic velocities.
