Low Reynolds number aerodynamics is important to a number of natural and man-made flyers. Birds, bats, and insects have been of interest to biologists for years, and active study in the aerospace engineering community, motivated by interest in micro air vehicles (MAVs), has been increasing rapidly. The primary focus of this book is the aerodynamics associated with fixed and flapping wings. The book consider both biological flyers and MAVs, including a summary of the scaling laws-which relate the aerodynamics and flight characteristics to a flyer's sizing on the basis of simple geometric and dynamics analyses, structural flexibility, laminar-turbulent transition, airfoil shapes, and unsteady flapping wing aerodynamics. The interplay between flapping kinematics and key dimensionless parameters such as the Reynolds number, Strouhal number, and reduced frequency is highlighted. The various unsteady lift enhancement mechanisms are also addressed, including leading-edge vortex, rapid pitch-up and rotational circulation, wake capture, and clap-and-fling.

This is an ideal book for graduate students and researchers interested in the aerodynamics, structural dynamics and flight dynamics of small birds, bats and insects, as well as of micro air vehicles (MAVs), which present some of the richest problems intersecting science and engineering. The agility and spectacular flight performance of natural flyers, thanks to their flexible, deformable wing structures, as well as to outstanding wing, tail and body coordination, is particularly significant. To design and build MAVs with performance comparable to natural flyers, it is essential that natural flyers' combined flexible structural dynamics and aerodynamics are adequately understood. The primary focus of this book is to address the recent developments in flapping wing aerodynamics. This book extends the work presented in Aerodynamics of Low Reynolds Number Flyers (Shyy et al. 2008).

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.

Insect-scale flapping wing flight vehicles can conduct environmental monitoring, disaster assessment, mapping, positioning and security in complex and challenging surroundings. To develop bio-inspired flight vehicles, systematic probing based on the particular category of flight vehicles is needed. This Element addresses the aerodynamics, aeroelasticity, geometry, stability and dynamics of flexible flapping wings in the insect flight regime. The authors highlight distinct features and issues, contrast aerodynamic stability between rigid and flexible wings, present the implications of the wing-aspect ratio, and use canonical models and dragonflies to elucidate scientific insight as well as technical capabilities of bio-inspired design.

"Flapping wing vehicles (FWVs) have unique flight characteristics and the successful flight of such a vehicle depends upon efficient design of the flapping mechanisms while keeping the minimum weight of the structure. Flapping Wing Vehicles: Numerical and Experimental Approach discusses design and kinematic analysis of various flapping wing mechanisms, measurement of flap angle/flapping frequency, and computational fluid dynamic analysis of motion characteristics including manufacturing techniques. The book also includes wind tunnel experiments, high-speed photographic analysis of aerodynamic performance, soap film visualization of 3D down washing, studies on the effect of wing rotation, figure-of-eight motion characteristics, and more. Features: Covers all aspects of FWVs needed to design one and understand how and why it flies; Explains related engineering practices including flapping mechanism design, kinematic analysis, materials, manufacturing, and aerodynamic performance measures using wind tunnel experiments; Includes CFD analysis of 3D wing profile, formation flight of FWVs, and soap film visualization of flapping wings; Discusses dynamics and image-based control of a group of ornithopters; Explores indigenous PCB design for achieving altitude and attitude control This book is aimed at researchers and graduate students in mechatronics, materials, aerodynamics, robotics, biomimetics, vehicle design and MAV/UAV."--

This intriguing book breaks new ground on an emerging subject that has attracted considerable attention: the use of unmanned micro air vehicles (MAVs) to conduct special, limited duration missions. Significant advances in the miniaturization of electronics make it now possible to use vehicles of this type in a detection or surveillance role to carry visual, acoustic, chemical, or biological sensors. Interestingly, many of the advances in MAV technology can be traced directly to annual student competitions, begun in the late 1990s, that use relatively low cost model airplane equipment. The wide variety of configurations entered in these contests and their ongoing success has led to a serious interest in testing the performance of these vehicles for adaptation to practical applications. MAVs present aerodynamic issues unique to their size and the speeds at which they operate. Of particular concern is the aerodynamic efficiency of various fixed wing concepts. Very little information on the performance of low aspect ratio wing planforms existed for this flight regime until MAVs became of interest and the proliferation of fixed wing designs has since expanded. This book presents a brief history of unmanned air vehicles and offers elements of aerodynamics for low aspect ratio wings. Propulsion and the basic concepts for fixed wing MAV design are presented, as is a method for autopilot integration. Three different wing configurations are presented in a series of step-by-step case studies. The goal of the book is to assist both working professionals and students to design, build, and fly MAVs, and do so in a way that will advance the state of the art and lead to the development of even smalleraircraft.

Modern Flexible Multi-Body Dynamics Modeling Methodology for Flapping Wing Vehicles presents research on the implementation of a flexible multi-body dynamic representation of a flapping wing ornithopter that considers aero-elasticity. This effort brings advances in the understanding of flapping wing flight physics and dynamics that ultimately leads to an improvement in the performance of such flight vehicles, thus reaching their high performance potential. In using this model, it is necessary to reduce body accelerations and forces of an ornithopter vehicle, as well as to improve the aerodynamic performance and enhance flight kinematics and forces which are the design optimization objectives. This book is a useful reference for postgraduates in mechanical engineering and related areas, as well as researchers in the field of multibody dynamics. - Uses Lagrange equations of motion in terms of a generalized coordinate vector of the rigid and flexible bodies in order to model the flexible multi-body system - Provides flight verification data and flight physics of highly flexible ornithoptic vehicles - Includes an online companion site with files/codes used in application examples
