Wingtip Vortices are a swirling vortex of air left by wings when it generates lift, but it also generates downwash that is the consequence of lift generation in three dimensions. Usually, winglets are used to alleviate this problem. But by observing and mimicking biological processes, many solutions might come out. One of them is by observing the shape of the wingtip of an Albatross bird that can change its wingtip angle or semi aeroelastic hinged wingtip. This is done with the hope that the shape of the wing increase lift/drag, decreases parking space needed for aircraft, and also increases stability and maneuverability. This idea of an adaptive wingtip might potentially be a beneficial design especially for aircraft that focuses on endurance like MALE UAV LSU 05. Therefore, further investigation is needed to study the effect of an adaptive wingtip, especially the aerodynamics with the help of computational fluid dynamics (CFD). But the positive effect generated by adaptive wing for the vortices are not conclusively seen in the case of LSU 05 UAV. This is because Lift/Drag value is lower than that of the conventional wing. It is possible that the use of winglets is superior than an adaptive wingtip.
