This journal discusses specifically about aircraft winglets. Numerical modelling of winglets on airplane wings using CFD is the author’s main activity. The author’s focus is to find out the effect of adding winglets of the wingtip fence type to the wingtips of the TBM 700 A aircraft that have not used winglets on the aerodynamic characteristics of the aircraft. The use of the winglet itself is to reduce the drag force in the form of vortex drag that occurs at the wingtip of the aircraft due to air movement from the lower area of the aircraft to the upper wing area. Simulation will be carried out using ANSYS by entering the condition of the aircraft when cruising at a speed of 128.66 m/s. Winglets without and with winglets were simulated under the same conditions using the NACA 4415 airfoil. The simulation results showed that the addition of winglets reduced the drag coefficient by 21.7%. In addition, the CL/CD ratio has increased by 6% which indicates the aircraft’s ability to fly. Overall, the results of this study show that the performance of the aircraft increases with the addition of wingtip fence type winglets in the aerodynamic profile of the aircraft, which will affect the aircraft’s ability and even reduce fuel consumption.
