Flapping-wing propulsion for a micro air vehicle
38th Aerospace Sciences Meeting and Exhibit, 2000 AIAA Paper No. 2000-0897, 38th AIAA Aerospace Sciences Meeting, Reno, Nevada, Jan. 2000. Recent interest in the development of micro-air-vehicles (MAVs) has led to a renewed interest in flapping-wing propulsion due to the relatively poor efficiencies of conventional propellers at these small scales.

Resonance Type Flapping Wing for Micro Air Vehicle
TRANSACTIONS OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, 2007 A resonance type flapping wing, which is suitable for an insect like Micro Air Vehicle, is presented. It utilizes the r esonance phenomenon of a two-degrees of freedom elastic system, that is, the wing is suppor ted by the spr ings for flapping and feathering motions, being oscillated, at the resonance frequency of the system, only by the torque in ...

Effect of Wing Corrugation on the Aerodynamic Efficiency of Two-Dimensional Flapping Wings
Applied Sciences, 2020 Many previous studies have shown that wing corrugation of an insect wing is only structurally beneficial in enhancing the wing’s bending stiffness and does not much help to improve the aerodynamic performance of flapping wings.
