Abstract

The influence of upper wing mounted engines on the aerodynamic interference of the transport aircraft is investigated numerically, focussing on cruise flight conditions. The geometry of the configuration is identical to the existing VFW614 aircraft, but without tail and fin. It is shown that the main effects are dominated by the flow above the wing in front of engine and pylon. Further effects result from the fact that engine, pylon, wing, and fuselage form a channel inboard of the pylon. Therefore the development of remarkable transonic regions at moderate freestream Mach numbers is established.
