To develop next generation aircrafts, the remarkable improvement of the economic efficiency such as fuel burn, environmental performance and the comfortability for passengers has been requested. The one of ideas for the next generation aircraft is the one which has a wide fuselage with upper mounted engines. This kind of aircraft has possibility to improve the aerodynamic performance by the optimum inlet flow. In this paper, the aerodynamic performance of the wide fuselage aircraft was investigated with deforming the fuselage geometry and displacing the engine nacelle. The intake/ exhaust flow is also simulated. According to investigation results, the design knowledge which achieved higher lift-to-drag ratio could be found out. In addition, it was also found that the lift was increased by the intake flow. These results suggested that the over-the-fuselage engine concept has possibility to be next generation civil aircraft which could improve the fuel economy and the environmental performance.
