This paper presents an overview of the on-going research activities at Shrivenham, aimed at the design of an autonomous flapping-wing micro air vehicle. After introducing the problem of insect wing kinematics and aerodynamics, we describe our quasi-three-dimensional aerodynamic model for flapping wings. This is followed by a brief discussion of some aerodynamic issues relating to the lift-generating leading-edge vortex. New results are then presented on modelling of wing aeroelastic deflections. Finally, some brief observations are made on flight control requirements for an insect-inspired flapping-wing micro air vehicle. Overall, it is shown that successful development of such a vehicle will require a multi-disciplinary approach, with significant developments in a number of disciplines. Progress to date has largely been concerned with hover. Little is known about the requirements for successful manoeuvre.

Small hand-held micro air vehicles (MAVs) can serve many functions unsuitable for a manned vehicle, and can be inexpensive and easily deployed. MAVs for indoor applications are underdeveloped due to their demanding requirements. Indoor requirements are best met by a flapping-wing micro air vehicle (FMAV) based on insect-like flapping-wing flight, which offers abilities of sustained hover, aerial agility, and energy efficiency. FMAV development is hampered by a lack of understanding of insect-like flapping-wing aerodynamics, particularly at the FMAV scale. An experimental programme at the FMAV scale (Reynolds number on the order of 104) was undertaken, investigating: leading-edge vortex (LEV) stability, flapping kinematic effects on lift and the flowfield, and wing planform shape effects on the flowfield. For these experiments, an apparatus employing a novel flapping mechanism was developed, which achieved variable three-degreeof- freedom insect-like wing motions (flapping kinematics) with a high degree of repeatability in air up to a 20Hz flapping frequency. Mean lift measurements and spatially dense volumetric flowfield measurements using stereoscopic particle image velocimetry (PIV) were performed while various flapping kinematic parameters and wing planform were altered, to observe their effects. Three-dimensional vortex axis trajectories were reconstructed, revealing vortex characteristics such as axial velocity and vorticity, and flow evolution patterns. The first key result was the observation of a stable LEV at the FMAV scale which contributed to half of the mean lift. The LEV exhibited vortex breakdown, but still augmented lift as Reynolds number was increased indicating that FMAVs can exploit this lifting mechanism. The second key result was the identification of the trends of mean lift versus the tested kinematic parameters at the FMAV scale, and appropriate values for FMAV design. Appropriate values for lift generation, while taking mechanical practicalities into account, included a flat wingtip trajectory with zero plunge amplitude, angle of attack at mid-stroke of 45 degrees , rotation phase of +5:5%, and maximum flapping frequency and stroke amplitude.

This book introduces the topics most relevant to autonomously flying flapping wing robots: flapping-wing design, aerodynamics, and artificial intelligence. Readers can explore these topics in the context of the "Delfly", a flapping wing robot designed at Delft University in The Netherlands. How are tiny fruit flies able to lift their weight, avoid obstacles and predators, and find food or shelter? The first step in emulating this is the creation of a micro flapping wing robot that flies by itself. The challenges are considerable: the design and aerodynamics of flapping wings are still active areas of scientific research, whilst artificial intelligence is subject to extreme limitations deriving from the few sensors and minimal processing onboard. This book conveys the essential insights that lie behind success such as the DelFly Micro and the DelFly Explorer. The DelFly Micro, with its 3.07 grams and 10 cm wing span, is still the smallest flapping wing MAV in the world carrying a camera, whilst the DelFly Explorer is the world's first flapping wing MAV that is able to fly completely autonomously in unknown environments. The DelFly project started in 2005 and ever since has served as inspiration, not only to many scientific flapping wing studies, but also the design of flapping wing toys. The combination of introductions to relevant fields, practical insights and scientific experiments from the DelFly project make this book a must-read for all flapping wing enthusiasts, be they students, researchers, or engineers.

?Pub Inc Micro air vehicles (MAV) provide an attractive solution for carrying out missions such as searching for survivors inside burning buildings or under collapsed structures, remote sensing of hazardous chemical and radiation leaks and surveillance and reconnaissance. MAVs can be miniature airplanes and helicopters, however, nature has micro air vehicles in the form of insects and hummingbirds, which outperform conventional designs and are therefore, ideal for MAV missions. Hence, there is a need to develop a biomimetic flapping wing micro air vehicle (FWMAV). In this work, theoretical and experimental research is undertaken in order to reverse engineer the complicated design of biological MAVs. Mathematical models of flapping wing kinematics, aerodynamics, thorax musculoskeletal system and flight dynamics were developed and integrated to form a generic model of insect flight. For experimental work, a robotic flapper was developed to mimic insect wing kinematics and aerodynamics. Using a combination of numerical optimization, experiments and theoretical analysis, optimal wing kinematics and thorax dynamics was determined. The analysis shows remarkable features in insect wings which significantly improve aerodynamic performance. Based on this study, tiny flapping mechanisms were developed for FWMAV application. These mechanisms mimic the essential mechanics of the insect thorax. Experimental evaluation of these mechanisms confirmed theoretical findings. The analysis of flight dynamics revealed the true nature of insect flight control which led to the development of controllers for semi-autonomous flight of FWMAV. Overall, this study not only proves the feasibility of biomimetic flapping wing MAV but also proves its advantages over conventional designs. In addition, this work also motivates further research in biological systems.

Over the past decade, the promise of achieving the level of maneuverability exhibited in insect flight has prompted the research community to develop bio-inspired flapping-wing micro air vehicles (FW-MAVs) . Flying insects employ their wings to produce lift to perform complex maneuvers. Mimicking insect capabilities could enable FW-MAVs to perform missions in tight spaces and cluttered environments, otherwise unattainable by fixed- or rotary-wing UAVs. The inherent mechanism of flapping-wing flight requires periodically-varying actuation, requiring the use of averaging methods for analysis and design of controllers for flapping-wing MAVs. The main objective of this research is establishing a rigorous theoretical framework from a control theory point of view that combines averaging theory and robust nonlinear control theory towards the design of flight controllers for general models of FW-MAVs. The point of departure of this work is the adoption of Kane's method to obtain equations of motion for multi-actuated, multi-body flapping-wing MAVs. The first contribution of the present work is the formulation of a framework which investigates the effect of multiple actuation, including the presence of a movable appendage (abdomen), on vehicle controllability. The resulting formulation establishes a mathematically precise framework which lays the groundwork for the development of theoretically sound control design strategies.
