Aerodynamic interference effects of jet engines installed at the tail of a generic business configuration are investigated using numerical flow simulations based on the solution of Euler equations. It is demonstrated that the channel contour formed by fuselage tail, pylon and nacelle dominates the flow behavior and also the resulting interference drag. A simulation based optimization process chain is then used to minimize the interference drag in cruise flight by applying the freeform deformation method for re-shaping of the fuselage tail.
