Flying insects are able to hover and perform agile maneuvers by relying on their flapping
wings to produce control forces, as well as flight forces, due to the absence of tail control …

Odonata (dragonflies and damselflies) are well-known but often poorly understood insects.
Their phylogeny and classification have proved difficult to understand but, through use of …

In the present work, we propose an optimization framework based on the active learning
method, which aims to quickly determine the conditions of tandem flapping wings for optimal …

This study integrates high-speed photogrammetry, 3D surface reconstruction, and
computational fluid dynamics to explore a dragonfly (Erythemis Simplicicollis) in free flight …

Animal wings deform during flight in ways that can enhance lift, facilitate flight control, and
mitigate damage. Monitoring the structural and aerodynamic state of the wing is challenging …

In this study, we investigated the backward free flight of a dragonfly, accelerating in a flight
path inclined to the horizontal. The wing and body kinematics were reconstructed from the …

Flying insects are of utmost importance in ecology and for human living conditions. Certain
species serve as indispensable pollinators to ensure the availability of food stuffs, while …

This paper presents the effects of wing kinematics on both normal forward flight and escape
flight of a dragonfly. A Navier–Stokes-based numerical model has been adopted, and results …

Flow control is the attempt to favorably modify a flow field's characteristics compared to how
the flow would have developed naturally along the surface. Natural flyers and swimmers …

Despite their enormous size, whales make their living as voracious predators. To catch their
much smaller, more maneuverable prey, they have developed several unique locomotor …
