Micro-structures, nanomechanical properties and flight performance of three beetles with different folding ratios [PDF]
Beilstein Journal of Nanotechnology, 2022 When beetles are not in flight, their hind wings are folded and hidden under the elytra to reduce their size. This provided inspiration for the design of flapping-wing micro aerial vehicles (FWMAVs).

Attentional Blink in Pilots and Its Relationship With Flight Performance [PDF]
Frontiers in Psychology, 2020 ObjectiveIn flight, military pilots need to monitor changes in the external environment and monitor the situation of the aircraft at the same time. Attentional blink (AB) reflects attentional blindness in time.

Extraordinary flight performance of the smallest beetles. [PDF]
Proc Natl Acad Sci U S A, 2020 Size is a key to locomotion. In insects, miniaturization leads to fundamental changes in wing structure and kinematics, making the study of flight in the smallest species important for basic biology and physics, and, potentially, for applied disciplines.

Enhanced flight performance in hoverfly migrants. [PDF]
iScienceMany animals undergo seasonal migrations in which they travel long distances aided by variations in morphology, physiology, and behavior. Here, we compare the flight characteristics, measured in a tethered flight mill, of autumn migratory and summer non-migratory morphs of the marmalade hoverfly Episyrphus balteatus (Diptera: Syrphidae), an ...

Feather holes and flight performance in the barn swallow Hirundo rustica [PDF]
Animal Cells and Systems, 2018 Feather holes are small (0.5–1 mm in diameter) deformities that appear on the vanes of flight feathers. Such deformities were found in many bird species, including galliforms and passerines. Holey flight feathers may be more permeable to air, which could

Experimental study of the wake interaction between two vertical axis wind turbines
Wind Energy, 2023 Wakes and wake interactions in wind turbine arrays diminish energy output and raise the risk of structural fatigue; hence, comprehending the features of rotor–wake interactions is of practical relevance.

On the wake deflection of vertical axis wind turbines by pitched blades
Wind Energy, 2023 Wake losses are a critical consideration in wind farm design. The ability to steer and deform wakes can result in increased wind farm power density and reduced energy costs and can be used to optimize wind farm designs.
