The wing aspect ratio (AR), that is, the ratio of the wingspan to the mean wing chord, is the
most important geometrical parameter describing an insect wing. While studies have shown …

The presence of a stable leading edge vortex (LEV) on steadily revolving wings increases
the maximum lift coefficient that can be generated from the wing and its role is important to …

This paper reports a fundamental investigation on the aerodynamics of two-dimensional
flapping wings in tandem configuration in forward flight. Of particular interest are the effects …

The flexibility of insect wings and model wings in flapping-wing micro air vehicles (FWMAVs)
is crucial to guarantee an economic flight. Since the wing deformation is bilaterally coupled …

Uncoupling the effects of aspect ratio, Reynolds number and Rossby number on a rotating
insect-wing planform Page 1 J. Fluid Mech. (2019), vol. 859, pp. 921–948. c Cambridge …

The leading-edge vortex (LEV) is well known for its contribution to the high-lift generation in
a wide variety of biological organisms, such as flying insects, auto-rotating samaras, and …

Dual-stage radial–tangential vortex tilting reverses radial vorticity and contributes to leading-edge
vortex stability on revo Page 1 J. Fluid Mech. (2023), vol. 963, A29, doi:10.1017/jfm.2023.196 …

Reynolds number (Re) for miniature insects is in the range of 80–10. Here, we study how the
aerodynamic forces change in this Re range when the flapping mode commonly used by …

The wake structures generated by rotating wings are studied numerically to investigate the
complex vortex formation and evolution in both near-wake and far-wake regions. Flat …

Inspired by the high performance of rotary and insect flapping wings capable of vertical take-
off and landing and hovering (VTOLH), a novel flapping wing rotor (FWR) has been …
