A Free-Flight Simulation of Insect Flapping Flight
Journal of Aero Aqua Bio-mechanisms, 2010 In insect flapping flight, non-equilibrium flight conditions such as takeoffs and uncoordinated turn are difficult to investigate with experiments or quasi-steady analysis. Here we develop a simplified rigid body dynamics solver with 6 degrees of freedom (DOF), by utilizing unit quaternions.

The effect of passive deformation of dragonfly wing on aerodynamic characteristics
Nihon Kikai Gakkai ronbunshu, 2016 Dragonflies can perform both of gliding and flapping flight and have high maneuverability in spite of small-size. The aim of this study is to develop Micro Air Vehicle (MAV) based on the flight of dragonfly.

Drones, 2021 Many drone platforms have matured to become nearly optimal flying machines with only modest improvements in efficiency possible. “Chimera” craft combine fixed wing and rotary wing characteristics while being substantially less efficient than both.

Uncovering the physics of flapping flat plates with artificial evolution [PDF]
, 2005 We consider an experiment in which a rectangular flat plate is flapped with two degrees of freedom, and a genetic algorithm tunes its trajectory parameters so as to achieve maximum average lift force, thus evolving a population of trajectories all ...

Biofluiddynamic scaling of flapping, spinning and translating fins and wings [PDF]
, 2009 Organisms that swim or fly with fins or wings physically interact with the surrounding water and air. The interactions are governed by the morphology and kinematics of the locomotory system that form boundary conditions to the Navier–Stokes (NS ...

Research on the Flight Performance of Biomimetic Moth Based on Flapping Function Control
Applied SciencesFlapping flight is an important mode of insect flight, and its unique flapping motion pattern enables it to fly efficiently in complex environments. This paper takes a biomimetic moth flapping-wing aircraft as the research object and proposes a periodic ...

Periodic and Chaotic Flapping of Insectile Wings
, 2015 Insects use flight muscles attached at the base of the wings to produce impressive wing flapping frequencies. The maximum power output of these flight muscles is insufficient to maintain such wing oscillations unless there is good elastic storage of ...

Can scalable design of wings for flapping wing micro air vehicle be inspired by natural flyers? [PDF]
, 2018 Lift production is constantly a great challenge for flapping wing micro air vehicles (MAVs). Designing a workable wing, therefore, plays an essential role. Dimensional analysis is an effective and valuable tool in studying the biomechanics of flyers.

Flight Dynamics of Flapping-Wing Air Vehicle [PDF]
AIAA Atmospheric Flight Mechanics Conference and Exhibit, 2008 The research and development efforts presented in this paper address the flight dynamics of a flapping-wing air vehicle (ornithopter). The 74-cm-wing-span ornithopter was equipped with an automatic flight control system that provides stability augmentation and navigation of the vehicle and flight data acquisition. Wind tunnel tests were conducted with
