A twist of the tail in turning maneuvers of bird-inspired drones Sci. Robot. (IF 26.1) Pub Date : 2024-11-20 Hoang-Vu Phan, Dario Floreano
A banked turn is a common flight maneuver observed in birds and aircraft. To initiate the turn, whereas traditional aircraft rely on the wing ailerons, most birds use a variety of asymmetric wing-morphing control techniques to roll their bodies and thus redirect the lift vector to the direction of the turn. Nevertheless, when searching for prey, soaring raptors execute steady banked turns without exhibiting
