Design and construction of an autonomous ornithopter
… propelled by flapping wings, also known as ornithopters, has been an area of interest because of its application to micro aerial vehicles (MAVs). These miniature vehicles seek to mimic small birds and insects to achieve never before seen agility in flight. This renewed interest has raised a …

Flight And Symbolic Modeling Of A 3D Printed Ornithopter
… involved in the design and flight of hovering ornithopters as well as the measurement and analysis of lift forces produced by wings flapping in air. First, a method was developed to 3D print functional flapping wings. The use of 3D printing technology has greatly expanded the possibilities for …

Bat Inspired Lifesize Ornithopter with Passive Lateral Wing Retraction
… project: a to-scale simplified bat-inspired ornithopter that can be remotely controlled, sustain flight, and passively retract and extend its wings laterally. VALKRIE mimics the dimensions and size of its biological counterpart, Hipposideros diadema, a medium-sized bat; setting its …

Design and prototype of a hovering ornithopter based on dragonfly flight
… By adjusting the initial angle of attack of the ornithopter's wings, we can artificially recreate varying stroke planes. A comparison of the resultant lift generated from different stroke planes showed that greater lift forces were generated with non-zero stroke planes as demonstrated in normal …

A Study on the Control, Dynamics, and Hardware of Micro Aerial Biomimetic Flapping Wing Vehicles
… or other biological modes of flight is called an ornithopter and is the original design of the first airplanes. Flapping wings hold much engineering promise with the potential to produce lift and thrust simultaneously. In this research, modeling and simulation of a flapping wing vehicle is …

The aerodynamic and structural study of flapping wing vehicles
… The research is focused on the large scale ornithopter design of similar size and configuration to a hang glider. By means of Theodorsen’s theory the aerodynamic forces on a thin aerofoil subject to heaving, pitching, and combined heaving and pitching motions are carefully studied. The …

Unsteady Nonlinear Aerodynamic Modeling and Applications
… and planform shape of a Pterosaur replica ornithopter. The objective functions included minimization of the required cycle-averaged aerodynamic power and maximization of the propulsive efficiency. The results show that there is an optimum kinematic parameter as well as planform shape to …
