This paper addresses the unsteady aerodynamic mechanisms in the hovering flight of the DelFly II flapping-wing Micro Aerial Vehicle (MAV). Stereoscopic Particle Image Velocimetry (Stereo-PIV) were carried out around the wings at a high framing rate. Thrust-force was measured to investigate the relation between the vortex dynamics and the...

Historically, helicopters with four rotors (quad-rotors) have been very uncommon, mainly due to the fact that most of the common payloads could be lifted using one or two rotors. However, the quad-rotor possesses some special characteristics that make it attractive. One would be the superior payload capacity. Two, is the simplicity of the...

The design of a relatively new genre of aerial robots—a full-scale, bird-like flapping wing flying robot—is analyzed, modelled and validated through real experiments in this paper. Quaternions are used instead of Euler angles in the dynamical model to represent the flying robot orientation in 3D space in order to realize smoother rotational...

Hovering flapping flight is inherently unstable and needs to be stabilized actively. We present a control mechanism that modulates independently the wing flapping amplitude and offset by displacing joints of a flapping linkage mechanism. We demonstrate its performance by high speed camera recordings of the wing motion as well as by direct...

The concept of an aircraft capable of both hover as well as fast forward flight (hybrid) has recently been implemented on unmanned aerial vehicles (UAV). Hybrid UAVs combine hover capability with long range and endurance. As UAVs are often required to operate without human intervention, there is a call for autonomous guidance of hybrid UAVs....

Investigated is the ability of the usage of small height ducted fans in multicopters for increase in the hover time and protecting the propellers and surrounding. A set of numerical and experimental investigations concerning duct aerodynamics and efficiency of electrical part (drive, speed controller, accumulator) was conducted. The effects of...

As one of the most important components of a flapping-wing micro air vehicle (FWMAV), the design of an energy-efficient flapping-wing has been a research interest recently. Research on insect flight from different perspectives has been carried out, mainly with regard to wing morphology, flapping kinematics, and unsteady aerodynamics. However,...

This paper describes the design, build and fly University of Glasgow Singapore (UGS) flapping wing MAVs using fabrication method such as laser cutting and Rapid Prototyping. The first prototype was made from acrylic using a laser cutting machine. The material was strong however it was brittle. The wings were made up of carbon rods and kite...

Here we present a new design for humanfriendly UAVs (Unmanned Aerial Vehicles). Contrary to conventional UAVs like gyrocopters or quadrocopters, the so called eMotionSpheres feature high process stability, long endurance and furthermore allow for a safe human-machine interaction. Since these features are essential for UAVs used in a production...

In this paper, a steady 3D numerical study has been conducted on a 90 mm counter rotating lift fan to investigate its aerodynamic performance. The effect of axial distance between the fans and rotor speed are studied. A low thrust generation has been revealed from the simulation results due to the unfavourable working condition for the upstream...

This research employs ecological interface design to improve the human machine interface of an existing ground control station for the supervisory control of UAV swarms. As a case study, a general ground surveillance mission with four UAVs is envisioned. An analysis of the swarming work domain is performed to generate a reduced set of means-end...

Creating an autonomous flying vehicle the size of a honeybee presents a number of technical challenges because of its small scale. As vehicle wingspan diminishes, angular acceleration rates increase, necessitating sensing and control systems with high bandwidth. Hovering demonstrations have so far required feedback from highspeed motion capture...

This paper proposes a method to detect dynamic objects in the images obtained by a small UAV. Two geometric constraints in multi-view images are used to classify each of the extracted featurepoints as static or dynamic. The first constraint is the epipolar constraint which requires static points to lie on the corresponding epipolar lines in the...
