Research on Transonic Aerodynamic Performance Impact of the Engine Nacelle

To achieve the purpose of raise the left and reduce the drag,the design of modern civil aircraft more and more concerns the impact between the various components of the aircraft.Aerodynamic interferences among components have considerable impact on the aerodynamic characteristics of complete aircraft.Favorable interferences which lead to satisfactory aerodynamic characteristics can be resulted from careful design integration of reasonable aerodynamic configuration.In this paper,the research which is based on CFD is presented on the impact of the aerodynamic interferences of wing-hanged nacelles to a supercritical wing during transonic flight.
