Abstract

Abstract Winglets are equipment that must be used by aircraft and unmanned aerial vehicles (UAV) in the modern era. The function of the winglet is to block the fluid flow jump from the lower side to the upper side on an aircraft wing. With the reduction of fluid flow jumps, it is expected that the wing's aerodynamic performance will increase. The researchers mostly made geometric variations of the winglets to obtain maximum results, namely the increase of lift and decreasing drag. This research was conducted using Ansys Fluent 19.0 with a turbulent model k-w SST. The freestream flow rate to be used is 10 m/s (Re = 2.34 x 104) with the angle of attack (a) = 0°, 2°, 4°, 6°, 8°, 10°,12°, 15°, 16°, 17°, 19° and 20°. The model of the specimen is an Eppler 562 airfoil with forward and rearward wingtip fence. From this study, it was found that a winglet with fence height equals the chord line length resulting in better aerodynamic performance than winglet with fence height equal to half the chord line length. It this shows that the winglet with fence height equals the chord line length which can reduce the fluid flow jump from the lower side to the upper side. It was also found that the use of the wingtip fence reduced the strength of vorticity magnitude on the z-axis compared to plain wings. This is due to the vorticity effect of the plain wing and wingtip fence on the flow of fluid passing through it.
