Measuring the costs of soaring, gliding and flap** flight in raptors is challenging, but
essential for understanding their ecology. Among raptors, vultures are scavengers that have …

For nearly a century Ludwig Prandtl's lifting-line theory remains a standard tool for
understanding and analyzing aircraft wings. The tool, said Prandtl, initially points to the …

Seabirds must often travel vast distances to exploit heterogeneously distributed oceanic
resources, but how routes and destinations of foraging trips are optimized remains poorly …

In this paper, we present a comprehensive and detailed review of dynamic soaring process,
and in particular, its application to unmanned aerial vehicles (UAVs). We start by explaining …

Dynamic soaring is a small-scale flight manoeuvre which is the basis for the extreme flight
performance of albatrosses and other large seabirds to travel huge distances in sustained …

Lockable joints are widely used in robotic systems and adaptive structures for energy
management and/or topology reconfiguration. However, it is still challenging to design a …

The pervasive use of unmanned aerial vehicles for both commercial and military operations
has undergone rapid development in the recent past. When designing unmanned aerial …
