Ontogeny of aerial righting and wing flapping in juvenile birds [PDF]
, 2014 Mechanisms of aerial righting in juvenile Chukar Partridge (Alectoris chukar) were studied from hatching through 14 days post hatching (dph). Asymmetric movements of the wings were used from 1 to 8 dph to effect progressively more successful righting ...

Modeling and emergence of flapping flight of butterfly based on experimental measurements [PDF]
, 2012 The objective of this paper is to clarify the principle of stabilization in flapping-of-wing flight of a butterfly, which is a rhythmic and cyclic motion.

Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1909 This paper is supplementary to one by the same author published in the 'Proceedings of the Royal Society' in 1899, "On Flapping Flight of Aeroplanes," communicated by the late Prof. George F. FitzGerald, F. R. S. Towards the end of that paper, the author refers to the subject of hovering, and points out that the method of his paper does not apply, in ...

Animal Flight Dynamics II. Longitudinal Stability in Flapping Flight
Journal of Theoretical Biology, 2002 Stability is essential to flying and is usually assumed to be especially problematic in flapping flight. If so, problems of stability may have presented a particular hurdle to the evolution of flapping flight. In spite of this, the stability of flapping flight has never been properly analysed.

A linear systems analysis of the yaw dynamics of a dynamically scaled insect model [PDF]
, 2010 Recent studies suggest that fruit flies use subtle changes to their wing motion to actively generate forces during aerial maneuvers. In addition, it has been estimated that the passive rotational damping caused by the flapping wings of an insect is ...

On the Proper Treatment of Dynamics in Cognitive Science
Topics in Cognitive Science, EarlyView., 2023 Abstract This essay examines the relevance of dynamical ideas for cognitive science. On its own, the mere mathematical idea of a dynamical system is too weak to serve as a scientific theory of anything, and dynamical approaches within cognitive science are too rich and varied to be subsumed under a single “dynamical hypothesis.” Instead, after first ...

Research progress on the wind tunnel experiment of a bionic flapping-wing aerial vehicle
工程科学学报, 2022 “Flapping wing” is a mechanism observed in the flight of birds, insects, and bats. The lift and thrust for a flight are generated by the active movement of wings. It was first specifically designed by Da Vinci.
