Abstract
During landing flights, birds often perform a perching maneuver, which allows them to land smoothly. In this work, we investigated the effect of wing sweep on the evolution of the instantaneous forces and the flow field during the perching maneuver. Our results indicate that swept wing generates higher aerodynamic forces, which is contributed by a stable leading-edge vortex (LEV).
