▪ Abstract “What force does an insect wing generate?” Finding answers to this enduring question is an essential step toward our understanding of interactions of moving objects with fluids that enable most living species such as insects, birds, and fish to travel efficiently and us to follow similar suit with sails, oars, and airfoils. We give a brief history of research in insect flight and discuss recent findings in unsteady aerodynamics of flapping flight at intermediate range Reynolds…

The effect of air viscosity on the flow around an insect wing increases as insect size decreases. For the smallest insects (wing length $R$ below 1 mm), the viscous effect is so large that

Clap and fling mechanism with interacting porous wings in tiny insect flight

TLDR
The results of the study show that the porous nature of the wings contributes largely to drag reduction across the Re range explored, and was larger for some porosities when compared with solid wings.

Dynamics, Control, and Stabilization of Turning Flight in Fruit Flies

TLDR
This approach combines kinematic data from flying insects and aerodynamic simulations to distill reduced-order mathematical models of flight dynamics, wing actuation mechanisms, and control and stabilization strategies used by flying insects.

Flexible clap and fling in tiny insect flight

TLDR
The immersed boundary method is used to simulate clap and fling in rigid and flexible wings and finds that the drag forces generated during fling with rigid wings can be up to 10 times larger than what would be produced without the effects of wing–wing interaction.

The basic physical principles underlying flapping flight in insects, results of recent experiments concerning the aerodynamics of insect flight, as well as the different approaches used to model these phenomena are reviewed.

Leading-edge vortices in insect flight

INSECTS cannot fly, according to the conventional laws of aerodynamics: during flapping flight, their wings produce more lift than during steady motion at the same velocities and angles of attack1–5.

TLDR
Man manipulation of the translational and rotational aerodynamic mechanisms may provide a potent means by which a flying animal can modulate direction and magnitude of flight forces for manoeuvring flight control and steering behaviour.

TLDR
The results of flow visualization experiments on tethered insects are reviewed in an attempt to identify the high-lift mechanisms actually employed, including the fling/peel mechanism, which is clearly used by some insects and which is probably a general phenomenon for flapping insect flight.

Unconventional lift-generating mechanisms in free-flying butterflies

TLDR
Train red admiral butterflies to fly freely to and from artificial flowers in a wind tunnel, and use high-resolution, smoke-wire flow visualizations to obtain qualitative, high-speed digital images of the air flow around their wings, show that free-flying butterflies use a variety of unconventional aerodynamic mechanisms to generate force.

TLDR
The large lift forces measured during flight episodes elicited from dragonflies tethered to a force balance appear to be produced by unsteady flow-wing interactions, indicating the existence of a whole new class of fluid dynamic uses that remain to be explored.

The wake dynamics and flight forces of the fruit fly Drosophila melanogaster.

TLDR
The flow visualizations and instantaneous force measurements of tethered fruit flies found no evidence for the shedding of wing-tip vorticity during the upstroke, and it is argued that this is due to an extreme form of the Wagner effect acting at that time.

The Aerodynamics of Free-Flight Maneuvers in Drosophila

TLDR
The results show that a fly generates rapid turns with surprisingly subtle modifications in wing motion, which nonetheless generate sufficient torque for the fly to rotate its body through each turn.
