| description | Effectively decreasing induced drag is of important significance for the aircraft to reduce the fuel consumption and increase the flight range. Numerical simulation with CFD methods are carried out to obtain the aerodynamic characteristics, especially the drag reduction effect of the fuselage and wing configuration with the fusion winglet. The results show that tip vortex is decreased and drag coefficient is obviously reduced. The bending moment coefficient can be increased by 3.2% and drag coefficient can be decreased by 4.2% when specifying the lift coefficient to be 0.5. |
