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

Micro air vehicles (MAVs) have wide application prospects in environmental monitoring,
disaster rescue and other civil fields because of their flexibility and maneuverability …

This paper sets out to investigate the vortex flow of spinnaker yacht sails, which are low-
aspect-ratio highly cambered wings used to sail downwind. We tested three model-scale …

Waterfowl use webbed feet to swim underwater. It has been suggested that the triangular
shape of the webbed foot functions as a lift-generating delta wing rather than a drag …

From the perspective of aeronautical engineers, this paper gives a systematical summary of
the technical aspects of bird flight that should be considered in the analysis and design of …

This study investigates the flow structures and aerodynamic performance of a slender delta
wing that has a sweep angle of 65 degrees and is equipped with acicular vortex generators …

It has been suggested that a stable Leading Edge Vortex (LEV) can be formed from the
sharp leading edge of asymmetric spinnakers, which are high-lift sails used by yachts to sail …

The effects of using nature-inspired needle-shaped vortex generators (VGs) on the
aerodynamic features of a 65°/35° double-delta wing were investigated experimentally in a …

Understanding how extrinsic factors modulate genetically encoded information to produce a
specific phenotype is of prime scientific interest. In particular, the feedback mechanism …

Fins, wings, blades and sails can generate lift and drag in both attached and separated flow
conditions. However, the common understanding of the lift generation mechanism holds …
