Biomimetic Wings for Micro Air Vehicles
BiomimeticsIn this work, micro air vehicles (MAVs) equipped with bio-inspired wings are investigated experimentally in wind tunnel. The starting point is that insects such as dragonflies, butterflies and locusts have wings with rigid tubular elements (corrugation) connected by flexible parts (profiling).

Development of an Insect-like Flapping-Wing Micro Air Vehicle with Parallel Control Mechanism
Applied Sciences, 2022 Most traditional flapping-wing micro air vehicles (FMAVs) adopt a serial control mechanism, which means that one drive corresponds to one degree of freedom.

The Energy Benefits of the Pantograph Wing Mechanism in Flapping Flight: Case Study of a Gull [PDF]
, 2015 Bird wings generally contain a 4-bar pantograph mechanism in the forearm that enables the wrist joint to be actuated from the elbow joint thus reducing the number of wing muscles and hence reducing the wing inertia and inertial drag.

Design of Wing Root Rotation Mechanism for Dragonfly-Inspired Micro Air Vehicle
Applied Sciences, 2018 This paper proposes a wing root control mechanism inspired by the drag-based system of a dragonfly. The previous mechanisms for generating wing rotations have high controllability of the angle of attack, but the structures are either too complex or too ...
