Application of Optimal Control Theory to Dynamic Soaring of Seabirds
- G. Sachs, P. Bussotti
- Environmental Science
- 2005
Optimal control theory is applied as a method for determining the minimum wind strength required for dynamic soaring of seabirds. Dynamic soaring is a flight technique by which seabirds extract… Expand

Optimal Wind Energy Extraction for Dynamic Soaring
- G. Sachs
- Environmental Science
- 1994
Dynamic soaring is a flight technique for extracting energy from a horizontal wind, whose strength varies with altitude. Optimal control theory is used for dealing with the problem of minimum wind… Expand
Dynamic Soaring in Shear Wind Regions Associated with Jet Streams
- G. Sachs, O. D. Costa
- Engineering
- 18 April 2012
Dynamic soaring enables an energy gain by transferring energy from the moving air in a horizontal shear wind region to the saiplane. There are shear wind regions associated with jet streams,… Expand
