With the addition of a wingtip fence, it has a significant effect on the shape of the vorticity magnitude behind the wing. From this study, it was found that the wingtip fence reduced the strength of vorticity magnitude on the x-axis and z-axis compared to plain wings. Two types of wingtips are used: forward and rearward wingtip fence. ![]() The model specimen is wing airfoil Eppler 562 with winglets. Reynolds number in this research was 2,34 x 104 with the angle of attacks are 0o, 2o, 4o, 6o, 8o, 10o, 12o, 15o, 17o and 19o. This research was done numerically by using the turbulence model k-ω SST. By increasing the lift as high as possible on the wing and lowering the drag as low as possible, it is expected that high aerodynamic efficiency will be achieved in air transportation. Today's aircraft designers tend to provide geometric modifications displayed in computational applications so that visualization of fluid flow can appear clearly. Therefore, aircraft designers pay great attention to wing modification. This is because most of the lifting force arises on the wing. By Newtons law, since there was a force which caused the air to be deflected downwards, an equivalent force in the opposite direction causes the wing to go. Wings on airplanes and Unmanned Aerial Vehicles (UAVs) have a very important role in the formation of lift forces.
