On the role of tail in stability and energetic cost of bird flapping flight.

ABSTRACT: Migratory birds travel over impressively long distances. Consequently, they have to adopt flight regimes being both efficient-in order to spare their metabolic resources-and robust to perturbations. This paper investigates the relationship between both aspects, i.e., energetic performance and stability, in flapping flight of migratory birds. Relying on a poly-articulated wing morphing model and a tail-like surface, several families of steady flight regime have been identified and analysed. These families differ by their wing kinematics and tail opening. A systematic parametric search analysis has been carried out, in order to evaluate power consumption and cost of transport. A framework tailored for assessing limit cycles, namely Floquet theory, is used to numerically study flight stabilit
