The wing morphology of bats is very diverse, and may correlate with energetic, behavioural, and ecological demands. If these demands conflict, wing shape may reflect compromise solutions. In this study, we compared the ...

Both wing size and wing shape affect the flight abilities of birds. Intra and inter-specific studies have revealed a pattern where high aspect ratio and low wing loading favour migratory behaviour. This, however, have not ...

Changes in the environmental conditions experienced by naturally occurring populations are frequently accompanied by changes in adaptive traits allowing the organism to cope with environmental unpredictability. Phenotypic ...

Inverse methods are mathematical techniques by which the unknown input of a system is determined from a known or desired output. In this article, a new inverse method for the reverse design of deformable structures is ...

A methodology to simulate the unsteady, nonlinear aeroelastic behavior of a folding-wing concept in multiple flight configurations is presented. It is based on a partitioned or co-simulation scheme, which divides the ...

A large body of research has shown how avian morphology is shaped by specific behavioral repertoires and life history traits. Yet, the majority of such research has been conducted on birds breeding at north-temperate ...

Chiroptera is the only group of mammals capable of powered flight. The mechanical basis of bat flight is well established, but evolution of its constituent aerodynamic variables remains poorly understood. Here, we determine ...

Inverse methods are powerful design tools that allow engineers to obtain efficient designs at much lower costs than the ones normally involved in experimental and direct computational design. Here we present an inverse ...

Remotely piloted aircraft, RPA, have a growing variety of applications over the past decades. During flight, such aircrafts are subjected to distributed aerodynamic loads that act on the aerodinamic center, respectively, ...

Certain birds have been noted to fly in V-formation, an arrangement which may be used to conserve energy when migrating over long distances without stopping and feeding. The use of such grouping arrangement and organized ...
