Induced drag analysis of multi-winglets for aerodynamic performance on NACA 23015 / Zaim Ariefin Azwan Affendi Nual

An eagle can reach high velocities and stay airborne for hours. It is believed that the capability of an eagle to do so is due to the multi-winglets during its gliding and soaring flight without flapping its wings. Multi-winglets as a device for reducing induced drag in unmanned aerial vehicles (UAV...
