Colloquium: Miniature insect flight

M Sun - Reviews of Modern Physics, 2023‏ - APS
Many of the existing winged-insect species are extremely small (wing length≈ 0.3–4 mm);
they are referred to as miniature insects. Yet, until recently much of our knowledge about the …

Novel flight style and light wings boost flight performance of tiny beetles

SE Farisenkov, D Kolomenskiy, PN Petrov, T Engels… - Nature, 2022‏ - nature.com
Flight speed is positively correlated with body size in animals. However, miniature
featherwing beetles can fly at speeds and accelerations of insects three times their size …

Aerodynamic performance of a bristled wing of a very small insect: Dynamically scaled model experiments and computational fluid dynamics simulations using a …

D Kolomenskiy, S Farisenkov, T Engels, N Lapina… - Experiments in …, 2020‏ - Springer
Aerodynamic force generation capacity of the wing of a miniature beetle Paratuposa

Flight efficiency is a key to diverse wing morphologies in small insects

T Engels, D Kolomenskiy… - Journal of the Royal …, 2021‏ - royalsocietypublishing.org
Insect wings are hybrid structures that are typically composed of veins and solid
membranes. In some of the smallest flying insects, however, the wing membrane is replaced …

Flow over a radiating multi-filamentous structure with various opening angles: From disk-like to cone-like shape

S Li, D Pan, L Zeng, J Li, X Shao - Physics of Fluids, 2024‏ - pubs.aip.org
Flow over a radiating multi-filamentous structure with various opening angles has been
investigated numerically at low and moderate Reynolds numbers. The opening angle, as the …

[HTML][HTML] Aerodynamic interaction of bristled wing pairs in fling

VT Kasoju, A Santhanakrishnan - Physics of Fluids, 2021‏ - pubs.aip.org
Tiny flying insects of body lengths under 2 mm use the “clap-and-fling” mechanism with
bristled wings for lift augmentation and drag reduction at a chord-based Reynolds number …

Stabilized motion of a freely falling bristled disk

M Lee, SH Lee, D Kim - Physics of Fluids, 2020‏ - pubs.aip.org
Several tiny insects have peculiar porous wings composed of many bristles and perform an
interesting passive flight known as parachuting. Despite numerous studies on the freefall of …

Aerodynamic response of a bristled wing in gusty flow

SH Lee, D Kim - Journal of Fluid Mechanics, 2021‏ - cambridge.org
Some microscopic flying insects have evolved bristled wings. In the low-Reynolds-number
regime they reside in, these porous wings perform like membranous wings because the …

M Lee, E Mahravan, D Kim - Journal of Fluid Mechanics, 2024‏ - cambridge.org
Although poroelastic clusters in nature, such as bristled wings and plumed seeds, exhibit
remarkable flight performances by virtue of their porous structure, the effects of another key …
