Numerical study of the aerodynamic characteristics of a “wing–fuselage–engine nacelle–pylon” three-dimensional layout of the engine for a wide-body long-range aircraft

The paper presents the numerical calculation results on the aerodynamic characteristics of a “wing–fuselage–engine nacelle–pylon” full three-dimensional layout for a wide-body long-range aircraft engine of optimal shape in a wide range of flight conditions. Aerodynamic analysis of the initial configuration is carried out using the OPTIMENGA_AERO_ANALYSIS software which is a computer system applied for a high-precision calculation of viscous flows near aerodynamic bodies of complex configuration. According to the analysis of numerical calculation results, the “wing–fuselage–engine nacelle–pylon of the engine” configuration for a wide-body long-range aircraft of optimal shape exposes significantly better aerodynamic characteristics compared to the baseline design in a wide range of Mach number and lift coefficient.
