Dynamic soaring - flight of the albatross - Blogionik
2017年11月23日 · Abstract: The Coanda effect and Newtons laws of motion can explain dynamic soaring where albatrosses glide into wind almost effortlessly to gain altitude and airspeed. The physics is similar to how boats can sail into a wind.
2022年11月1日 · In this paper, we assume that albatrosses control their wing camber, taper, etc, so as to maintain a constant (usually the maximum) value for L/D. We will show that this assumption reduces the flight equations of motion to a simple differential equation that is straightforward to solve analytically in many cases of interest.
[2202.12822] A novel hypothesis for how albatrosses optimize …
2022年2月25日 · Abstract: The albatross optimized flight maneuver -- known as dynamic soaring -- is nothing but a wonder of biology, physics, and engineering. By utilizing dynamic soaring, the bird can travel in the desired flight direction almost for free by harvesting energy from the wind.
Experimental verification of dynamic soaring in albatrosses
2013年11月15日 · Experimental results from tracking 16 wandering albatrosses (Diomedea exulans) in the southern Indian Ocean show the characteristic pattern of dynamic soaring. This pattern consists of four flight phases comprising a windward climb, an upper curve, a leeward descent and a lower curve, which are continually repeated.

2009年1月1日 · Albatrosses can make use of the dynamic soaring technique extracting energy from the wind field to achieve large-scale movement without a flap, which stimulates interests in effortless flight...
(PDF) The enigma of Albatrosses’ dynamic soaring is explained …
Albatrosses can cross oceans without flapping their wings for the same reasons that boats can sail around the world into the wind. Newtonian mechanics (Force = ma) explains how albatrosses gain...
Optimal dynamic soaring consists of successive shallow arcs
2017年10月4日 · Dynamic soaring is the flight technique where a glider, either a bird or a machine, extracts its propulsive energy from non-uniform horizontal winds such as those found over the oceans. Wandering albatrosses (Diomedea exulans), the archetypal dynamic soarers, have been recorded to travel 5000 km per week while relying on wind energy alone [1–3].
Dynamic soaring: aerodynamics for albatrosses - Semantic Scholar
This analysis constitutes a general framework for dynamic soaring and more broadly energy extraction in complex winds, geared to improve the characterization of pelagic birds flight dynamics and habitat, and could enable the development of a robotic albatross that could travel with a virtually infinite range.
The Mechanisms of Albatrosses’ Energy-Extraction During the Dynamic Soaring
Then in the nineteenth century, Lord Rayleigh first used dynamics soaring to refer albatrosses’ soaring technique [2, 3], and divided dynamic soaring cycle into four parts: Windward climb, High altitude turn, Leeward descent, Low altitude turn, as shown in Fig. 1.
Dynamic soaring: aerodynamics for albatrosses - IOPscience
2008年11月6日 · Albatrosses have evolved to soar and glide efficiently. By maximizing their lift-to-drag ratio L/D, albatrosses can gain energy from the wind and can travel long distances with little effort. We simplify the difficult aerodynamic equations of motion by assuming that albatrosses maintain a constant L/D. Analytic solutions to the simplified ...
