Hovering efficiency comparison of rotary and flapping flight for rigid rectangular wings via dimensionless multi-objective optimization
TL;DR: The proposed framework is capable of generating sets of optimal solutions and Pareto fronts for maximizing the lift coefficient and minimizing the power coefficient in dimensionless space, explicitly revealing the trade-off between lift generation and power consumption.

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.

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

Controlled Flight of a Biologically Inspired, Insect-Scale Robot
TL;DR: An 80-milligram, insect-scale, flapping-wing robot modeled loosely on the morphology of flies is built and demonstrated tethered but unconstrained stable hovering and basic controlled flight maneuvers, which validates a sufficient suite of innovations for achieving artificial, insects-like flight.
