A parametric study of flapping wing performance using a robotic flapping wing

2009 IEEE International Conference on Robotics and Automation, 2009
Flapping wings have the potential to revolutionize the field of Micro Aerial Vehicles (MAVs), however the effect of flapping motion on the performance of such wings has not been studied in detail. This paper presents a parametric study of flapping wing propulsion, using two types of passive flapping wings and three flapping motions. Each combination of

Design, aerodynamic analysis and test flight of a bat-inspired tailless flapping wing unmanned aerial vehicle

, 2021
This paper provided a design of bat-inspired tailless flapping wing unmanned aerial vehicle (UAV) based on the biological data of the large flying fox. The wing span of the UAV is 1.68 m and the total mass is 289 g.

Unsteady aerodynamic model of flexible flapping wing [PDF]

Aerospace Science and Technology, 2018
Bio-inspired flapping wing has potential application to micro air vehicles (MAV). Due to the nature of lightweight and flexibility of micro flapping wing structures, elastic deformation as a result of aeroelastic coupling is inevitable in flapping motion.

Wing Analysis of Bionic Flapping-Wing Flying Robots

2023 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2023
Flapping-wing flying robots, as a newly emerging research hotspot, have attracted more and more researchers' attention. Compared with traditional aircraft, flapping-wing flying robots have the characteristics of high flight efficiency, good concealment, and have a wide range of application prospects.

Influence of wing camber on aerodynamic performance of flapping wing rotor

, 2021
The flapping wing rotor (FWR) is a new type of micro aerial vehicles (MAV), which generates lift through active flapping and passive rotation of antisymmetric wings.

Optimization Design of Flapping Mechanism and Wings for Flapping-Wing MAVs

2008
In this paper, a lightweight flapping-wing MAV (micro air vehicle) was built which can successfully fly in the sky. However, this flying MAV often pitches toward left or right and crashes during flight. It is mainly caused by the incomplete symmetry of the wings' movement.

A review on flapping-wing robots: Recent progress and challenges

Int. J. Robotics Res.
This paper analyses the methods and technologies involved in flapping-wing flying robots (FWFRs), where the actuation of the flapping wing produces thrust and lift force that mimics birds’ and insects’ flight.

Mechanisms of collision recovery in flying beetles and flapping-wing robots

Science, 2020
Protection in the wings Beetles have hardened forewings for the protection of their bodies and hindwings, and their use during crawling or burrowing is well understood.

The modeling and numerical solution for flapping wing hovering wingbeat dynamics

, 2021
The production of wingbeat motion of flapping wing hovering flight are determined by the actuating, aerodynamic and inertia forces/moments, which influence the dynamic unsteadiness and controllability of flapping wing flying.
