Insects, birds, and bats that power and control flight by flapping their wings perform excellent
flight stability and maneuverability by rapidly and continuously varying their wing motions …

The morphological structure and airborne behavior of maple samaras have attracted
increasing attention due to their potential use in wind turbines and air vehicles. This study …

Unlike the tail of a bird, regarded as a separately controlled aerodynamic surface, the
membrane tail of a bat is operated as a dynamic trailing-edge flap. We investigate the effects …

Flying insects exhibit remarkable capabilities in coordinating their olfactory sensory system
and flapping wings during odour plume-tracking flights. While observations have indicated …

In recent years, physics-informed neural networks (PINNs) have shown potential as a
method for solving combustion physics. However, current efforts using PINNs for the direct …

Flying insects can achieve remarkable and robust flapping aerodynamic performance and
flight stability in various environments partially owing to the passive mechanisms of their …

To overcome the technical challenges of the multi-blade centrifugal fan, such as low
efficiency and insufficient total pressure, the blades of the fan were optimally designed in this …

To overcome the technical challenges of the multi-blade centrifugal fan, such as low
efficiency and insufficient total pressure, the single-arc blades of the fan were optimized and …

Biological flapping flights in insects, bast and birds are generally characterized by wave
phenomenon in terms of flapping-wing motions and body oscillation. Here we unravel a …
