The requirement to reduce the specific fuel consumption of future advanced transport aircraft, in order to achieve definite improvements in the areas of economy and ecology, has resulted in dedicated activities among others in two fields of aeronautics. In the area of propulsion the current trend in the development of turbofan engines is directed towards very high and ultra high bypass ratios with the objective to lower the specific fuel consumption and the noise level. In the area of aerodynamics the laminarization of extensive surface areas of the airframe wetted by the external flow aims at a reduction of the skin friction drag. Since the higher bypass ratios of the advanced powerplants are associated with a growth in the engine nacelle dimensions, not only the skin friction drag rises, but the problem of engine-airframe integration is also intensified due to negative engine-airframe interactions. Therefore there is a challenge to an efficient integration of.
