Insect-inspired, tailless, hover-capable flapping-wing robots: Recent progress, challenges, and future directions
Hoang Vu Phan,Hoon Cheol Park +1 more
TL;DR: The capability of free flight and flight endurance of the FWAVs, which are limited by current electronics and power technologies that severely constrain those vehicles using other driving actuators, rather than conventional electromagnetic motors, to freely take off, are discussed.

Unsteady aerodynamic and optimal kinematic analysis of a micro flapping wing rotor
TL;DR: In this paper, a novel flapping wing rotor (FWR) was developed by combining the above two types of wing motions, which offers an alternative configuration for micro air vehicles (MAV) of such high flight performance.

TL;DR: System identification of flower tracking reveals that moths also display reduced-order dynamics in wind compared with still air, and persistence of a stable LEV during decreased flower tracking demonstrates the interplay between hovering and maneuvering.

Extremely large sweep amplitude enables high wing loading in giant hovering insects.
TL;DR: The results indicate that the sweep amplitude as high as 190 deg is more beneficial for power requirements than the smaller amplitudes, which require higher frequencies resulting in higher inertial powers to produce the same vertical force.

Effect of wing-wing interaction coupled with morphology and kinematic features of damselflies.
TL;DR: The results reveal that a damselfly with the forewing in the lead can have an effective aerodynamic performance in flight, and as an application, in the design concept of a micro-aircraft, increasing the amplitude of the hindwing might enhance the wing-wing interaction, thus controlling the flight modes.

Wing rotation and the aerodynamic basis of insect flight.
TL;DR: In this paper, the authors show that the enhanced aerodynamic performance of insects results from an interaction of three distinct yet interactive mechanisms: delayed stall, rotational circulation, and wake capture.
Wing rotation and the aerodynamic basis of insect flight
TL;DR: A comprehensive theory incorporating both translational and rotational mechanisms may explain the diverse patterns of wing motion displayed by different species of insects.

Oscillating foils of high propulsive efficiency
TL;DR: In this article, the phase angle between transverse oscillation and angular motion is the critical parameter affecting the interaction of leading-edge and trailing-edge vorticity, as well as the efficiency of propulsion.

The Aerodynamics of Hovering Insect Flight. IV. Aeorodynamic Mechanisms
TL;DR: In this paper, a full derivation of the vortex theory of hovering flight is presented, which relates the lift produced by flapping wings to the induced velocity and power of the wake.
